SNIPEFEST 99 
... Valda Dedman 


This was a great success. The 
weather and the snipe co-operated 
most wonderfully and the kids and 
helpers had a great time. We sang 
the snipe song and turned children 
into ‘stripey’ snipe with face paint and 
masks, found lots of snipe food in the 
water and were rewarded with 17 
snipe on view, one of which flew right 
over the watchers’ heads. 


My sincere thanks to all of you who 
came along to help. You made my 
task of organisation so easy. Thanks 
to the golf club too for making their 
clubhouse available for the mask 
activity. 


Next year | would like to apply for a 
grant to provide buses to help less 
fortunate schools to attend, as well 
as extending an invitation to those 
who have already experienced 
Snipefest to come back for more.

Leaders: Barry Lingham and 
Margaret MacDonald. 


Margaret will be our guide on this 
day as we visit the heathlands at 
Anglesea and other areas to view 
wildflowers. After lunch we will 
probably walk along the ridge at 
Mogg's Creek. 


A bus has been booked and names 
will be taken at the meeting. We 
will be leaving from Karingal at 
9.00a.m. and should return mid 
afternoon. 


As many of you know, Margaret

OUT AND ABOUT WITH VALDA 


-.. Valda Dedman 


Biodiversity and Belmont Common 
(again!), morning magpie, slugs 
and snails, new babies, the 
strangest bird | ever did see, orchid 
hunting with the new book, 
woodswallows and... 


National Biodiversity Month has 
just finished. We didn't have time 
to celebrate it, because all our 
efforts were directed towards trying 
to save the biodiversity of Belmont 
Common. One of the main points 
of the GFNC submission to 
Amendment R243 of the Greater 
Geelong Planning Scheme was 
that a watersports complex across 
the Barwon River floodplain in 
Belmont would result in a loss of 
ecological values and regional 
biodiversity. We have been fighting 
this battle for nearly four years and 
“we do hope that the end is in sight. 


There have been some amazing 
submissions from objectors. 
Thousands of Geelong people 
have poured their hearts out on 
paper. Now we just have to hope 
that Council will heed their cry, will 
not be influenced by mere 
numbers, or think their concerns 
can be accommodated. 


The matter comes up before 
Council on 13th October. at 7.30 
pm at the Council Chambers. Join 
me there in a show of solidarity. 
But be early if you want a seat! 


So | haven't been out and about as 
much as | would have liked. There 
is still lots of interest in the home 
garden though. For months great 
flocks of Rainbow Lorikeets have 
been noisily feeding in the 
flowering eucalypts across the 
road. At long last the magpie has 
given up calling over and over and 
over for at least half an hour before 
the dawn chorus. To my pre-dawn 
brain it seemed to be saying, 
“That's incredible. No it is not!” 


The rain brought out the snails, 
those voracious European imports. 
My garden snail population has 
changed over the years. When we 
first came to Highton, there were 
also some ‘stripey’ dune snails and 


GEELONG NATURALIST Vol 35 No. 6 October 1999 


tiny conical ones, smaller than my 
little finger nail. My favourite snails 
are the Black Otway Snails, shiny 
black and found in the forest litter. 


Strangely, | have never seen a 
European snail in my vegetable 
garden at Pollocksford. There are 
lots of fat juicy slugs (they love my 
compost bin too) and bright yellow 
flatworms. In winter when the soil is 
moist earthworms as thick as a 
pencil and up to 15 cm long are 
common. | think they retreat further 
down in the soil in summer, 
because | never see them then. 
We turned over a plank that had 
been outin the weather for months. 
Lurking underneath were lots of 
lovely centipedes. 


Lily Sherwood has another lot of 
babies in her Westringea. The 
Masked Lapwing that lives opposite 
the caravan parks in Barrabool 
Road was out feeding with a chick 
the other day. Another successful 
breeding. 


The strangest bit of biodiversity for 
the month was the Black-tailed 
Yellow Cockatoo (no that is NOT a 
misprint) | saw in Clarke's Road 
Anakie. And | was perfectly sober 
at the time. And | had witnesses - 
my U3A students. Practically the 
whole of the upper half of the bird 
was bright yellow. It was perched in 
a eucalypt with 22 normal Yellow- 
tailed Black-Cockatoos. They had 
been feeding on pine cones. 


We had stopped to admire a 
beautiful creamy froth of flowers on 
a stand of Hazel Pomaderris. The 


Fairy Waxflower was looking 
beautiful too, just round the corner 
in De Motts Road. Clarke's Road is 
a good spot for Waxlip orchids 


Orchids are flowering very early 
this year but don't let that deter you 
from setting off to Anglesea, new 
field guide in hand, to see what's 
still about. The new book is, of 
course, Orchids -of the Anglesea 
District, by Everett Foster and 
Margaret Macdonald ($25 and 
available from Angair). It's fully 
illustrated, spiral bound for ease of 
use in the field AND It has all the 
new botanical names, with 
reference to the old ones, as well 
as a name derivation, which | find a 
great aid to memory and a help in 
identification. Flowering time, local 
habitat and local conservation 
status are added bonuses. 


I've just had a few days in the 
Sunset Country (again). The honey 
flow was strong in the White 
Mallees and flocks of White- 
browed Woodswallows were 
systematically dipping into each 
nectar filled flower cup, just like 
honeyeaters. 


And... it’s Ibis time again. Look up 
for those lovely vee-formations. 
Look up, too, if you hear an 
enormous twittering. It could be 
that the woodswallows are in town. 
Charles Belcher said they arrived 
“on the wings of the north wind” 
about the end of October. Most will 
be White-browed, but the odd one 
or two with the white underbelly 
will be Masked Woodswallows, 
really dark ones will be Dusky. 
Look around you for butterflies. 
Cabbage Whites have been out 
and about for months, and it will 
soon be time for Common Browns 
and Wanderers, Imperial Whites, 
Grass Blues and others. Will 
anyone see the Club emblem, the 
Small Ant Blue? It's rare and 
protected under the Flora 8 Fauna 
Guarantee Act. Is it really locally 
extinct, only occurring now in 
Victoria at Mt Piper near 
Broadford? Is there a hilltop near 
you with wattles and coconut ants, 
where males might congregate 
prior to mating in late spring or 
early summer? What should the 
Club be doing about its loss from 
Geelong?

PRESIDENT'S REPORT 


. Barry Lingham 


October 1999 


The future of the Belmont Common 
is looking more promising, thanks 
„to the efforts of the thousands of 
Geelong people who took the time 
to make a submission opposing 
changes to the Planning Scheme 
that would have allowed the 
construction of a Water Sports 
Complex. 


Valda Dedman and Trevor Pescott 
submitted a comprehensive report 
on behalf of the GFNC and Valda 
has been kept busy checking the 
submissions as they were received 
at the Planning Department. The 
recent election results have also 
added extra pressure to the issue. 
Coupled with this is the damning 
submission from the Corangamite 
Catchment Authority noting the 
problems of blue-green algae 
growth that would occur in a rowing 
course. 


It will be interesting to see how the 
City of Greater Geelong councillors 
react to all this; hopefully they will 
respond to the overwhelming 
evidence against the proposal and 
vote against the Water Sports 
Complex. 


Simon Birrell from the Otway 
Ranges Environment Network 
warned us of the many problems 
caused by logging in the Otway 
State Forests at our September 
meeting. Graeme Tribe and | will 
be making a submission on behalf 
of the GFNC concerning the 
Regional Forest Agreements 
related to the Otways. We have 
purchased several copies of the 
Research Report published by 
OREN and it is hoped that 
members familiarise themselves 
with these issues. 


Many of our members enjoyed a 
morning with local Primary school 
children involved in the Snipefest 
on the 14" of September. From 
the letters of thanks sent by the 
children, they all had a great time 
as well as learning about the 
importance of wetlands and the 


October 1999 


wildlife that inhabits them. 
thank you to Valda and all her 
helpers for making this occasion a 
great success. 


Next March, the Geelong Field 
Naturalists Club will be hosting the 


Victorian Field Naturalists Club 
Campout on the Bellarine 
Peninsular. This will involve a 


range of excursions, activities and 
workshops. We will be looking for 
assistance with a range of tasks 
that will be necessary if this long 
weekend is to be a success. 
Please note the dates of March 11- 
13 on your diary so you can 
become involved. 


| have been given several 
suggestions for possible speakers 
or excursion sites for next year’s 
program. These suggestions are 
much appreciated - if you have 
some ideas please let me know or 
pass on a message to a committee 
member. |

A list of current GFNC Office and 
Duty Holders has been prepared. | 
will attempt to confirm all positions 
with those concerned before it is 
published - if you perform a duty on 
behalf of the Club could you please 
check with me to see that you have 
been included on the list. 


The annual Publications Review 
Meeting will be held on Thu 28" 
October. We are very proud of our 
publication which has been praised 
by many other Field Naturalists 
Clubs, and we are keen to maintain 
a relevant and interesting 
publication for our members. 
Please pass on any items that 
could be discussed to Alban Lloyd- 
Jones or Barry Lingham. We are 
also keen to hear from anyone who 
could assist in the compiling and 
editing of the Naturalist.

BIRD GROUP REPORT 


-.. Barry Lingham 


September 21° 1999 


Trevor Pescott is well known to 
members of the GFNC and the 
Geelong public, being an 
acknowledged expert on many 
aspects of local natural history. 
Trevor is a resident of Belmont, but 
he also has a second home near 
Forrest where he can indulge in his 
love of the Otway Ranges. 


Trevors Otway home lies at 
Yaugher, a small hamlet that is 
about 2 kilometres north of Forrest 
on the road to Barwon Downs. The 
river flats of the West Barwon 
River form the main habitat of the 
site, but heathy woodlands border 
the one acre property and the wet 
sclerophyll forests surrounding 
Forrest lie a short distance away. 


Low lying wetlands fed from the 
East Barwon River occur past the 
Seven Bridges Road intersection 
on the road to Barwon Downs. 
This range of habitats gives rise to 
a wide variety of species visiting 
Trevor's property. 


When first observing the birds of 
Yaugher, Trevor made a decision 
to rely on visual observation and to 
avoid any banding program. Two 
watering places were established to 
allow closer observation and 
photographing of the birds. The 
sandy soils made this a difficult 
task and eventually concrete was 
required to prevent seepage of 
water in the main water hole. 


Swans frequent a large paddock 
nearby where potatoes are grown 
in summer. Australian Shelduck 
also use this paddock. Other 
paddocks nearby appear to offer a 
similar habitat type but are not 
used - the reason for this remains a 
mystery. 


Other ducks seen include Pacific 
Black Duck, Chestnut Teal and 
Wood Duck. Australian and Hoary- 
headed Grebes frequent the 
wetlands along with Little Pied 
Cormorants and White-faced 
Heron. Cattle Egrets arrive around 
March to April each year. 


GEELONG NATURALIST Vol 35 No.6 October 1999 


Raptors included Black-shouldered 
Kite, Swamp Harrier, Wedge-tailed 
Eagle and the magnificent white 
phased Grey Goshawk. 


Although rarely seen, Trevor 
believes the Painted Button-guail is 
probably reasonably common in 
the heathland. Common and Brush 
Bronzewings are both observed in 
the area. 


Many parrot species can be seen. 
Yellow-tailed Black-Cockatoo are 
present in summer. Other parrots 
include the Gang-gang and 
Sulphur-crested Cockatoo, Long- 
billed Corella and Crimson Rosella. 
Blue-winged Parrots nest in the 
Peppermint/Stringybark forest. 
King Parrots are rarely seen 
although they are common only 
two kilometres away at Forrest. 


Similarly, Forrest residents often 
note Satin Bowerbirds, Pied 


Currawong and House Sparrow, yet 
they are rarely noted at Yaugher. 


Boobook Owl are reasonably 
common and hunt insects attracted 
to lights at the house. A Barn Owl 
was noted from a road kill. Trevor's 
photo of a Tawny Frogmouth 
perched on a white roadside 
guidepost in the middle of the day 
was most unusual. 


Some of the “bush birds” include 
Kookaburra, White-throated 
Treecreeper, Superb Fairy Wren, 
Striated Pardalote (occasional), 
and White-browed  Scrubwren. 
Thornbill species were Brown, 
Yellow-rumped and Striated. 


The Noisy Miner is common at 
Barwon Downs and is slowly 
extending its territory northwards. 
Other honeyeaters are Yellow- 
faced (resident breeder), White- 
naped, White-eared, Brown- 
headed (which makes a fur nest 
shaped like a tennis ball), 
Crescent, New Holland and 
Eastern Spinebill. 


Jacky Winters prefer the open 
farmland, Flame Robins nest in the 
wet forest and Yellow Robins are 
very approachable. A juvenile 
Olive-Whistler ate bird seed from a 
feeder from December till August. 
Golden Whistlers and Grey Shrike- 
thrush are commonly seen. 


Grey Fantails in summer have 
slightly different markings to the 


winter birds. Other species seen 


were Dusky Woodswallow, Grey 
Butcherbird (in open forest), 
Australian Magpie, Grey 
Currawong, Forest Raven (with a 
massive beak) and Little Raven 
(from Jan. to March) 


Red-browed Firetail are fairly 
common, but the Beautiful Firetail 
is rarely seen. Welcome Swallow, 
and Tree Martin are seen chasing 
insects. Silvereyes are present for 
most of the year. 


Bassian Thrush nest in the wetter 
months whilst a single pair of 
Blackbirds is established at the 
site. Starlings favour one particular 
spot on the property. Emu Wrens 
and Bristlebirds are restricted to the 
wet heathlands. 


The observations showed a 
contrast between the species found 
at Yaugher and those found a short 
distance away at Forrest, due to 
changes in habitat type. 


Trevor has had his photographs 
included in many publications and 
he showed us some superb 
examples of his skill during his 
interesting talk. Thank you Trevor. 


Next Month's Speaker 


lan Morgan is a farmer from 
Rupanyup in the Wimmera. He 
has been observing and 
photographing birds for more that 
forty years and he will speak to us 
on the “Birds of the Wimmera”

BIODIVERSITY NOTES 


... Dennis Greenwell 


Our excursion on 12th September 
had an unusual start to say the 
least. As it turned out in the end, we 
all had the benefit of a good laugh, 
whereas, we may just as a easily 
have ended up being 
detained by the local 
constabulary on an 
extremely serious charge. 
But let me explain. 


The handful of ‘regulars’ 
turned up as arranged, 
outside the Green Grub at 
Waurn Ponds Shopping 
Centre, prior to our 
departure to the Iron Bark 


October 1999 


We hurriedly established that Helen; 
from the Geelong Bushwalkers’ Club 
had arranged to meet them at either 
the Green Grub or later at either 
Point Addis or Iron Bark Basin, so 
rather than turn back, we drove on 
to the Point. When we arrived, 
there was nobody there, so Mary 
tried to ring Helen on the mobile, but 
there was no reply so we invited 
them to join us exploring Ironbark 


Orchids from the Anglesea area. 


Found by Biodiversity Group of GFNC - 12/9/99. 
... Compiled by Dennis Greenwell 


All were in flower at the time. Listed only for the first 
place we saw them.

Apart from that interesting incident, 
we had a very rewarding day, first at 
Ironbark Gorge as previously 
mentioned and then at the Anglesea 
Heathland bordering Forest Road. 


The most outstanding feature was 
the 21 species of orchid in flower at 
the two places, which surely must be 
some kind of record. We were also 
rewarded with the appearance of an 
Echidna which was spotted 
by our youngest group 
member Gabriel Scheeling 
and the first Australian 
Admiral Butterfly this Spring. 


A list of orchids is included..

A BRIEF LOOK AT PLANT VASCULAR SYSTEMS 


by Dave King 


nk 
DRR 


Unit 216/86 Church Street, Grovedale, 3216. 
Introduction 


As a result of conducting an illustrated talk at the August meeting of the Plant Group the writer was requested to 
produce an article on the subject. Of necessity it is to be brief, - the subject being a wide one, would involve 
something approaching a book. To fully appreciate the extent of a plant's vascular system it is vital to view the 

` tissues under a microscope, which was the basis of the talk by the writer. It is a very revealing activity, even when 
using the simplest equipment. 


General Description 

The plant vascular system is the means by which water, that contains nutrients from the soil, is conducted from 
the roots to all parts of the plant. By the same means food, produced by photosynthesis in the leaves, is 
distributed throughout the plant. Two principle tissues are involved. Xylem is the principal water conducting 
tissue, phloem the principal food conducting tissue. Spatial relationship between these tissues varies according to 
whether a dicot or monocot, and in this context only angiosperms are considered. Gymnosperms are not here 
considered. 


In all cases, between the xylem and phloem tissues, a meristematic tissue is present. This tissue is referred to as 
the vascular cambium. Its function is the production of new cells by repeated division. They are small closely 
packed cells with large nuclei and thin walls. 


Differentiation of the cambium cells produces the xylem cells toward the stem centre, and phloem cells toward the 
stem periphery, Fig. 1. The difference is shown between the dicot and monocot vascular systems. In the 
monocot, the system consists of discrete vascular bundles. With the dicot they form bundles closely connected in 
the form of a cylinder, the continued growth forming the familiar growth-rings of arboreous or woody plants. In 
many arboreous plants an additional tissue is initiated in the cambium, this tissue is observed as rays radiating 
from the centre of the stem. Ray tissue is instrumental in the lateral distribution of water and food products. 


The xylem and phloem as they mature become elongated vertically to become vessel cells. Xylem cell walls 
progressively become lignified with spiral and annular thickening as they extend in length. Eventually with 
dissolution of the end walls they become continuous vertical tubes. At maturity these cells are dead, thus forming 
the woody interior of the stem, Fig. 2. By contrast phloem cells, as they mature, form sieve tubes. The end walls 
become perforated, known as sieve plates, thus forming a continuous vertical tube interspersed with sieve plates. 
Phloem at maturity forms the circular bark tissue, remaining basically a living tissue, Fig. 2. 


Interpretation 

To interpret the vascular system it is necessary to produce transverse and longitudinally cut sections, i.e. sections 
cut at right angles and cut parallel to the long axis of the stem respectively. These sections need to be as thin as 
possible in order to observe the cellular tissues clearly. In order to master the process it is advisable to choose a 
specimen that is relatively soft and not too woody. A number of sections should be cut, then choose those that 
appear most satisfactory, before proceeding further. Cutting should be done with a razor blade having a single 
edge (Gem or similar), a "cut-throat" razor or a scalpel. 


The cutting instrument and plant sample must be kept moist with water in order to make a clean cut. Transfer the 
cut sections to a water bath with a fine paint brush. Sort sections for the most suitable, and using the brush, 
transfer the section to a microscope slide. Remove excess water from the section with a tissue. To enhance the 
difference between types of tissue it is necessary to stain the section. In this particular exercise the stain used was 
toluidine blue. The stain is applied to the section on the slide using a brush and allowed to remain for one to two 
minutes. Apply a drop of water to dilute the stain and soak up with a tissue. Apply a drop of clean water and 
carefully cover the section with a glass cover slip, avoiding air bubbles being trapped. 


The section is now viewed under a compound microscope, using medium power, say 80x to 100x. If the section 
has been carefully prepared the various tissues will be easily distinguished. Toluidine blue reacts with the various 
chemical compositions of tissue to produce a variety of colour. Pectic substances, found in the ground tissue stain 
pinkish blue. Lignin and tannin stain greenish blue to bright blue. Cellulose and starch are not stained, the latter 
often found in tissue of the bark region. What this means is the vascular bundles will stand-out from the ground 
tissue, xylem with thick cell walls stains blue, cambium cells a band of greeny-blue, and phloem cells with a 
mixture of pink and blue. 


Many other stains, such as eosine (red ink) can be used to obtain specific differentiation affects. For further 
information on their use the literature should be consulted.

BACKYARD BIRDS IN BACCHUS MARSH, AUGUST 1999 


by Marilyn Hewish 


97 Grey St., Bacchus Marsh, 3340 


| have been too busy lately to spend much time in the bush, but have still had some rewarding bird-watching 
experiences. The records in the Geelong Bird Report attest to the many native bird species which are just as 
at home in towns as in the bush. Some of our most valuable collections of records come from the 
conscientious people who keep detailed records of birds in their back gardens and suburbs in Geelong. We all 
know who they are! 


Following their example, | present here a list of some interesting birds which | have noticed in or over our 
garden on the outskirts of Bacchus Marsh in August. 


White-necked Heron 
A single bird was seen flying over the garden on 12/8 and 21/8. This species is rather uncommon here as in 
most parts of the Geelong region, and | haven't seen any locally in the past few years. 


Galah 

In 1998 we played host to 2 Galahs from July to December. They spent each day in the garden digging out 
bulbs of Thread Iris with their bills, leaving large bare pits in the grass and chewed bulbs over the surface. 
Occasionally they were joined by friends, and a flock of 13 was present on 7/11. It was fascinating to watch 
them digging vigorously and with great determination, covering their bills and faces with dirt. Over the months 
their excavations destroyed the ground cover at the end of the garden. They left early this year, probably 
because the ground was bone-dry and as impenetrable as concrete. We were delighted to see that 7 birds had 
re-appeared on 15/8, working over ground that had been softened by rain. We don't object to their activities; 
its a small price to pay to have such endearing visitors. 


Purple-crowned Lorikeet 

Small flocks are feeding in flowering eucalypts in the carpark of one of our local supermarkets at present. On 
the morning of 7/8 | could hear flocks flying past our house just after sunrise, probably moving out from their 
night-time roosts. They are usually more common here in spring and summer; for instance, up to 25 birds 
were feeding in flowering eucalypts nearby in November-December 1998. 


Eastern Rosella . | 
A record of a bird during a dawn watch on 7/8 was the first for several months. A pair has been seen regularly 
in the garden for two weeks since then, feeding in our grass. 


Striated Pardalote 
These birds occur occasionally here, usually as single birds passing through or staying for a few days in our 
trees. One bird was heard calling persistently on the morning of 7/8. 


Superb Fairy-wren 

A small family group has lived here year-round since November 1993, dividing their time between 3 adjacent 
gardens. The gardens are large with stands of dense shrubs and expanses of short grass, and are separated 
by wire fences so that the Wrens can move freely between them. This area was developed for housing in 
1988, previously consisting of open fields. It seems the shrubs and trees planted by the new home-owners 
took 5 years to develop enough to support the wrens. 


Yellow-rumped Thornbill 

These occur in small numbers here, and can turn up at any time of year. They feed on our ‘lawn’ in small 
flocks, busily fossicking and hopping about with their soft trilling calls. | love to see the flash of their bright 
yellow rumps in the brown grass. During most of August there have been 2-3 birds hanging around, 
occasionally we get flocks of up to 15. 


Grey Shrike-thrush 

Shrike-thrushes occur regularly in our garden during autumn-winter, generally April-August. They are often 
heard calling (in 1999 on 3/4-5/4, 20/4, 5/6, 3/7, 1/8, 7/8, 15/8) and single birds or pairs occasionally feed in 
the grass under our trees. Most of my records are on weekends because on weekdays in winter | leave the 
house in the dark and arrive home in the dark.

(Continued from page 8) 


Zebra Finch 

Our house is on the edge of town close to extensive dry grasslands. Small flocks of Zebra Finches can be 
recorded here at any time of year. They are probably resident in the general area, moving around to feed on 
seeding grasses. The grassland began on the other side of our street when we moved here in 1992, and flocks 
of 10-20 Finches fed on our ‘lawn’ (which is not real lawn but mown dry grassland). This area has since been 
covered with high-density housing with smooth green lawns, and the Finches now occur in smaller numbers 
(e.g. 1-2 birds on 15/8), usually flying over. 


Common Myna ` 

It seems a pity to lower the tone, but Mynas are impossible to ignore in our garden at the moment. They have a 
roost nearby so we hear their raucous calling every morning and evening. | first noticed them on 1/3/99, when 
about 100 birds went into a roost in a eucalypt next door. They made a huge racket and the gathering and 
calling took an hour before the birds disappeared into the roost tree. It must have been a new roost - | would 
have noticed them before. At first they gathered in a line of tall poplar trees, but they were continually disturbed 
by 4 Australian Magpies. The Magpies were not directly harassing the Mynas, but simply flying over. The 
Mynas seemed nervous, perhaps because they were trying out a new roost in unfamiliar territory. They soon 
gained access to the poplars however. By 7/3, the flock was divided between the eucalypt and the poplars and 
by 20/3 most were using the poplars. But then the poplars began to lose their leaves for winter. The flock 
decreased to 55-60 birds by 3/4, with the roost moving away from the poplars and circulating between various 
eucalypts. At present, | can still hear the birds each morning and evening but the roost is out of sight from our 
garden. 


Common Starling 

There is also unfortunately a roost of Starlings near our house. | counted 210 birds gathered on the telegraph 
wires by our house on the evening of 5/4, and they eventually roosted in the Myna eucalypt and a nearby 
Hakea bush. They shared both roosts with Mynas, apparently peacefully. By 18/4 they had taken over the Myna 
tree. Whether the Mynas were forced out or moved voluntarily | don’t know. At present about 100 Starlings fly 
through our garden each morning before sunrise as they leave the roost; but the roost location is not known. 


This is an interesting tally of native birds for a suburban garden. There are other species which | haven't 
mentioned, such as the ubiquitous Red Wattlebirds, White-plumed and New Holland Honeyeaters, Australian 
Magpies, Magpie-larks and Willie Wagtails, and other rarer visitors. 


We have a good and varied garden bird list. We have the advantage that all the houses on our side of the road 
are on large blocks. The owners have planted many native trees and shrubs but not replaced the grassland with 
lawns. Now that the taller vegetation has developed we attract birds which are foliage-feeders (honeyeaters, 
pardalotes, lorikeets), but retain enough open unrestricted space for ground-feeders (Eastern Rosellas, Grey 
Shrike-thrushes, Yellow-rumped Thornbills), seed-eaters (Zebra Finches) and birds which prefer a mosaic of 
shrubs and open areas (Superb Fairy-wrens). Across the road, the houses on smaller blocks with tall fences, 
exotic plants, and fertilised, watered and mown lawns attract fewer native birds. Unfortunately the growing trees 
also attract Starlings and Mynas. 


There are some distinct differences in the bird populations seen by Geelong bird-watchers and Bacchus Marsh 
observers. Zebra Finches are regularly recorded in Bacchus Marsh. They are largely confined to the Werribee 
Plains and surrounding towns, not reaching as far south as Geelong. It would also be unusual in Geelong to 
have Superb Fairy-wrens resident in a suburban garden, and Yellow-rumped Thornbills and Grey Shrike- 
thrushes which are regular and probably always in the general area (Shrike-thrushes in autumn-winter only). 
We also often get bush birds visiting the garden, probably from nearby forests and woodlands (e.g. Brown 
Thornbills, Scarlet Robins, Restless Flycatchers, Brown-headed Honeyeaters, Rufous Whistlers) and birds from 
grasslands which surround the town (raptors including Black Falcons, Black Kites and Spotted Harriers, Barn 
Owls, Richard's Pipits, Golden-headed Cisticolas, Flame Robins). Spiny-cheeked Honeyeaters spend the winter 
here. 


Geelong bird-watchers can see several species which we don’t have, such as Rainbow Lorikeets, Grey 
Butcherbirds, Crested Shrike-tits, Pink Robins and Pied Currawongs, and others which are rare or in low 
numbers here, such as Grey Fantails, Gang-gang Cockatoos and Yellow-tailed Black-Cockatoos. | wonder why 
the Pied Currawongs which live in the Wombat Forest north of Bacchus Marsh have not yet discovered the 
town. In their daily dispersal in winter they come within 1-2 km of the town fringes. City living agrees with them, 
as they have invaded Geelong and now breed there. | enjoy them in the forests but would rather they didn’t 
come into the town to drive away our other native birds. 


In both Bacchus Marsh and Geelong, the bird-watchers and the native birds unfortunately have to endure the 
ever-present Starlings and Mynas. í

EXCURSION REPORT 


... Roy Whiteside 


Report of excursion to Brisbane 
Ranges on 15 Aug 1999 


This excursion was attended by 


about 20 persons and was led by 
Dick Southcombe and Roy 
Whiteside. 


GEELONG NATURALIST Vol 35 No. 6 October 1999 


The object of the excursion was to 
explore the circuit to be known as 
the Ted Errey Circuit in order to 
identify the main features 
(particularly plants) at various points 
so that appropriate details can be 
included on signs to be displayed at 
strategic points along the track. 


This circuit combines existing 
walking tracks and includes parts of 
Aqueduct Track, Nelson's Track, 
Anakie Gorge Walk, Outlook Walk 


Due to the length of the circuit the 
members divided, with each group 
covering parts of the whole circuit. 


The weather was fine and views of 
Mt. Anakie, Corio Bay and the You 
Yangs were quite clear. Lunch was 
taken at the Stony Creek Picnic 
Area with the accompaniment of a 
colony. of nine White-winged 
Choughs, some Brown 
Treecreepers and Crimson Rosellas. 
The excursion concluded at 4.15pm.

UNUSUAL CUTTLEBONE BEACH-CASTE AT OCEAN GROVE 


by Chris Gray and Lachlan Sinnott 


Chris Gray, Unit 2 87 Ocean Throughway Ocean Grove. Vic. 3226 
Lachlan Sinnott, 7 Constellation Court, Taylors Lakes. Vic. 3038 


Two specimens of the cuttlefish Sepia whitley and (Iredale 1926) Sepions found beach-caste on 2/1/99 at Ocean 
Grove Victoria probably drifted from their known habit range waters in Eastern Australia — from the Gulf of 
Carpentaria to northern New South Wales. It is usually caught as a ‘bycatch’ in the prawn and mixed species 
trawl fisheries at water depths of 23 — 160 metres. (Carpenter and Niem 1998) 


Both specimens had a cartilaginous shield posteriorly on the dorsal side. The reduced spine on the larger 
specimen suggested that the spine grows with the outer cone as it becomes prolonged similar to that reported 
for Sepia Apama. Bell 1979. 


The unusual number of easterly wind systems that occurred over the summer period was probably the reason 
for the drift of the two specimens so far south into Bass Strait waters. 


Special thanks to Dr. Amanda Reid Melbourne Museum for identification of the cuttlebone.

LYMANTRIIDAE 


THE TUSSOCK MOTHS 
by Ade Foster 


8 Hazel Street, Belmont, 3216 
ade 
The specimen table at the last meeting held an interesting wingless female moth, a Tussock moth, 
Lymantriidae. The family Lymantriidae contains 2500 species worldwide in about 200 genera. Although they 
are found on all continents except Antarctica, their strongest representation is in the tropical regions of Africa 
and Asia. Australia has 70 species in 16 genera, mostly across the north and down the east coast. 


They are robustly built moths with broad wings and wingspans from 16 - 100 mm, although the wings are 
sometimes reduced or entirely absent in females. Many have prominent labial palpi giving a characteristic- ` 
‘peaked’ appearance. Adults are usually densely hairy. 


Eggs are usually laid in batches and often covered by a tuft of a furry substance, in fact special deciduous" 
scales from the base of the female's abdomen. These are a camouflage mechanism and protect the eggs 
from discovery by predators. Sm 
The young larvae spin long strands of silk, which are picked up by air currents, and carry the little caterpillars 
sometimes surprising distances. This method of dispersal is extremely important for those species with 
wingless females. 


The caterpillars have dense and long secondary setae, or hairs, often arranged in four tufts on the back, like 
toothbrushes. Hence the common name - tussock moths. These hairs are often urticareous and can cause 
severe reactions in humans. In some cases larval hairs are incorporated in the cocoons and even carried on 
the bodies of adults causing severe rashes and eye and throat irritations. In some susceptible people, even 
wind-blown hairs can cause severe reactions. 


The larvae feed on a variety of native and introduced plants including Acacia, Eucalyptus, and Exocarpus as 
well as introduced fruit trees such as apple, pear, cherry, apricot, and other agricultural crops - passionfruit, 
broad bean, lupins and dahlias. They are also known to feed on Pinus radiata and various Cupressus and 
many others. Pupation takes place in a loosely spun silken cocoon, usually placed in the foliage of the food 
plant, or under loose bark. 


Wingless females do not leave the cocoon but attract males with pheromones. The males of these species are 
active day flyers. Wingless females have no gut and barely functional legs, they are basically big sacs of 
genitalia and eggs. Males of the winged female species come readily to lights at night. 


The specimen on our table was the female of a common local species, Teia anartoides, the males of which 
are quite small, orange and brown day fliers. The larvae of T. anartoides feed primarily on Acacia.

Report of talk given by Dave King at members night on 3 August 1999 
on the subject of the Rail Trail on the Bellarine Peninsula. 
-.. Roy Whiteside 


The overall trail is a State initiated project to put a trail completely around Port Philip Bay, starting at Queenscliff 


and ending at Portsea. The only gap in the trail would be across the sea between Queenscliff and Portsea which is 
serviced by ferries. : 


The Council of the City of Greater Geelong and National Parks, Victoria have put some money into the project 
which will cover from the border of the Queenscliff Shire through the Bellarine Peninsula and Geelong to Little 
River. The route through the Bellarine Peninsula is via the old railway track between Queenscliff and South 
Geelong. After 1972 the Steam Preservation Society took over the section of the railway between Queenscliff and 


Drysdale. The rails have been removed from the remaining sections of the old railway track between Curlewis and 
South Geelong. 


STAGE 1. Drysdale to Moolap Station Road. 


It is intended that the present railway route be extended from Drysdale to Curlewis when funding becomes 
available. This would reguire flashing lights and boom gates at crossings near Drysdale (ie. at Portarlington and 
Jetty Roads). The proceeds from the sale of removed rails has been ploughed back into the rail trail. There. are 
sections of the trail from Drysdale to South Geelong that need to be developed. The section between Drysdale and 
Moolap Station Road is fully developed for the use of walkers, cyclists and horse-riders. There is a proviso that 
horse-riders keep off the walking track. Road crossings have been completed with the highest safety incorporated 
and notices have been placed to suit the habitat. At Moolap Station Road there will be a node point where a 
simulated railway platform will be built with interpretation boards, car parking , picnicking area, tree planting (which 
has already started) and toilets. It will be a place where all cycling and walking events are planned to take place. 
Further tree planting will occur between there and Drysdale. It is proposed that "friends of the trail" groups be 
responsible for various sections of the trail. Schools' groups from Drysdale are already involved. The old Bellarine 
Shire Nursery in Drysdale is a good base for developing seedlings for tree planting. 


STAGE 2 Moolap Station Road to South Geelong. 

Part of this section has been surfaced and tree planting has taken place. Hepner's Funeral Services have become a 
sponsor and they are doing planting along the Bellarine Highway where the trail crosses. These trees are a 
memorial to deceased persons whose funerals have been conducted by Hepners and other funeral services. 
Beyond Coppards Road and as far as Breakwater Road the old rail is suitable for walking but reguires grading for 
cycling. 


STAGE 3. Drysdale to Queenscliff. 


Tenders have been let for the walking track development and the result will be known shortly. At "the narrows" near 
the former Queenscliff High Schoot they will pick up the existing track. In the region between Portarlington Road 
and Queenscliff Roads there is a fair amount of work to be done. This is probably the best area for natural history 
as there is more natural vegetation of the Bellarine Peninsula (eg. the native raspberry). Itis also a very scenic 
area with a spectacular view across the bay to the You Yangs. Interpretation boards will be erected where major 
drainage channels enter the creek and also at Suma Park. 


In the Geelong urban area, existing roads will have to be used and designated to pick up Eastern Park and then 
follow the bay via Steampacket Gardens, Rippleside, St Helens, Cowies Creek, Hovell's Creek to Lara (details of 
this latter area still have to be worked out). 


Much further work needs to be done on the overall project and it is hoped that further sponsors can be found from 
major fifms. If this is achieved then the trail should be of "world class" standard. 


Barry Lingham gave a' vote of thanks to Dave for all the work he has put into the scheme.
