MARYLAND BIRDLIFE jButtztin oj- ths <^A/[arij[anA (Dmitfiotocj ica[ 52li, was banded by Mrs. James Downes on September 21, 1961 at South Londonderry, Vermont, and was recaptured there on September 27. Eleven days later this bird was caught at Rock Run Sanctuary. A Black-capped Chickadee, number 101- 9921*5, which was banded by Burton Whitman at Brunswick, L&ine, on October 2, 1961, was captured at the sanctuary on November 26 and repeated on December 3 and 9. Twenty-five other birds of this species were banded at Rock Run during the influx of this species in the 1961-62 winter. An Operation Recovery Station was manned in cooperation with the U.S, Fish and Wildlife Service for seventeen days during September and October. Over this period 1*98 birds of 1*9 species were banded. A spring banding program has been started at the sanctuary and will he operated during MArch, April, and May, March 1952 MARYLAND ' BIRDLIFE 13 Banders plan to make a breeding -bird census at Rock Run during the summer months of 1962, and there is hope that the Operation-Recovery Station at Rock Run will be in operation during the months of August, September, and October with much better coverage than was possible in 1961 * The information collected by the banders at the sanctuary is available to ornithologists who are studying such things as the relationship between wing length and age and sex, the relationship of fat deposits to departure of migrants, and the color of eyes and plumage characteristics as they relate to the age and sex of certain species. As soon as any new data on determining age or sex is dis- covered it is used by other banders in their studies. A male Indigo Bunting, number 6U-18U29 , banded at Rock Run on August 7* I960, returned on May 26, 1961. The season ahead is awaited most anxiously by all the banders. Will any of the ten Ruby- throated Hummingbirds banded in 1961 be recaptured after spending the winter in Mexico or Panama? Will any of the birds that passed through the sanctuary boundaries on their way south be recaptured traveling to northern breeding grounds? Perhaps, Indigo Bunting number 6I4-I8U29 will return to the sanctuary again in 1962, We wait, but while we are waiting more birds are banded and more information is being collected at the Maryland Ornithological Society *s Rock Run Wildlife Sanctuary. 36 Burke Ave, Towson COMING EVENTS Apr. 1 Apr. 3 Apr. 5 Apr. 5 Apr. 7 Apr. 8 Apr. 8 Apr. 8 Apr. 10 Apr . 13 Apr. 14 Apr. 15 Apr. 15 Apr. 15 Apr. 17 Apr. 18 Apr. 18 Apr. 20 TALBOT breakfast hike, 7 A.M.
