FIELD OBSERVATIONS

Dr. Martin Edwards of Kingston, Ontario, discovered a male oldsquaw
on San Francisco Bay near Fort Baker on March 13. Between that date
and March 31 many members of Golden Gate Audubon observed the old-
squaw at close range near Fort Baker (east of the Golden Gate Bridge),
Marin County. We found him a very cooperative photographer’s model.

Highlights for the Mt. Diablo Audubon SocieL^’s Christmas Count
held December 27 were 18 cliff swallows, 1 European widgeon, 1 prairie
falcon, and 2 chipping sparrows — reported in the the April Quail by Lynn
Farrar. Ed. Note: A prairie falcon was perched on a bare tree limb near the
summit of Mt. Diablo on March 7 and allowed me to aproach within 40
feet of him, but he flew off as I was setting up my camera tripod.

FOR THE CHILDREN

The next meeting will be on Saturday, May 22, at the Rotary Natural Science
Center at Lake Merritt, Oakland, and will be led by Mr. Paul Covel. It is open to all
children, but those under eight years of age must be accompanied by an adult, and all
adults must be accompanied by children. The trip starts at 10:30 a.m. and will be
over a httle after 12. Bring your lunch.

Directions for reaching the waterfowl refuge, duck feeding area, and Rotary
Natural Science Center in Lakeside Park: From San Francisco, after leaving the Bay
Bridge Toll Plaza, take the Mac Arthur Freeway — Highway 50 to the Harrison Street
exit, turn right on Harrison to Grand Avenue, then left on Grand for a long block to
the Lakeside Park entrance. Drive tlrrough the park to the “Duck Pond.” The B bus
from San Francisco stops at Grand Avenue and Perkins St. — one block from tire
“Duck Pond” and Natural Science Genter.

Goslings and Ducklings

Goslings are baby geese. You will be sure to see on Lake Merritt a large gray^ brown
goose with a black head and neck and a white neckband. This is the Canada Goose.
It builds its nest on the shores of Lake Merritt hr a safe place, usually on the islands
in tire lake. Here several feet from the water a large nest is built out of sticks arrd leaves
and well hned with goose down plucked from tire bird’s breast. The eggs, as many as
nine, are large measuring 3/2 mches in length, and 2% wide. They are a duU yellowish-
white. After laying the eggs the mother goose sits on them for about 28 days until the
goslings hatch. At this time they are about as large as a three-week old deciding. Soon
after hatching, the baby birds are taken to the water and then across to the lawns on
the other side. Here wlrile the parents feed upon seeds and grass the young ones find
tiiry insects to gobble up. At iright the mother takes them back to the irest and broods
them or keeps them warm and safe. When Ganada Geese goslings hatch they are tannish
in color but after 10 days they turn gray. Since they have not yet exchanged their
nestling down, or first feathers, for real featliers it is probable that the grayness appears
as the feathers begin to grow out.

You will also be seeing plenty of baby ducklings too. Motlier and Father Mallard
look quite different, for he has a splendid green head and a white necktie and a tail
with a saucy httle curl at the end, while she is a streaky brown and never has a curly
tail. The way you can tell that tliey are both mallards is by what is known as the specu-
lum or shoulder pad of deep purple bordered along the edges with black and white. A
mallard builds its nest nearer to the water than a Ganada Goose does. This nest is
hidden in the weeds or grasses and is built of leaves and grasses and also very warmly
lined with down. Duck eggs are only a httle larger than hen’s eggs and are yellowish
or pale greenish white. A mother mallard may lay anywhere from 5 to 14 eggs, and it
is not unusual to find a brood of 11 or 12 following her around on Lake Merritt. She
sits on the unhatched eggs for 23 to 24 days and the baby ducklings when hatched are
dark brownish with a stripe through the eye. Mother Mallard calls to her young from
time to time when they are swimming on the lake because she wants to keep them
near her. One wonders whether she can count them all and sometimes it is true that
one duckhng wanders off and she seems to lose track of him — at least for a while. She
too takes her ducklings back to the nest at night to keep them warni. It isn’t long before
they begm to sprout real feathers and when they do the young look like their mother
and not their father, though they do have the same wing markings as both of tlieir
parents.

You should have a wonderful time with Mr. Covel. He takes lots of cliUdren on
field trips and knows the best places to go and the finest things to see. Have a good
time! - JANET NICKELSBURG, Education Chairman
