FOR OR FROM YOUNG OBSERVERS 



BIRD-STUDY AT HOME 



Many people are discouraged in starting a bird-list because it seems such an 

 undertaking. They have to walk two or three miles and then only see a few 

 birds, but if you keep your eyes open and use your ears you need not go out of 

 your own yard to see such birds as will start you well on your list. My yard is 

 such a yard as you would find in the residence section quite near the heart of 

 any large city. It is about 50 feet long by 25 feet wide. It is surrounded by a 

 cherry, an elm and plum trees, together with a clump of large lilac bushes on 

 one side, a poplar tree, lilac bushes and a flowering quince and shrubbery on 

 the other. I try to protect the birds from their enemies and I have two baths to 

 which have come Robins, English and Song Sparrows, Flickers, and Gold- 

 finches. I also have four feeding-devices which have been patronized by Robins, 

 Slate-colored Juncos, House Wrens, Ruby-crowned Kinglets, English, Song, 

 Chipping, White-throated, and White-crowned Sparrows. 



I had many interesting experiences in observing some of the birds. In the 

 morning of May 18 I saw a Brown Creeper on a telegraph pole in another yard 

 and went nearer to be sure of its identification. Coming back I scared up an 

 Oven-bird. When I came home from school it was raining but that did not 

 prevent me from seeing a Black-throated Blue Warbler, House Wren, and Wood 

 Thrush. In the afternoon it stopped raining and I saw four Canada Geese. I 

 had an interesting time with a Nashville Warbler in the quince bush. He would 

 always keep on the other side from me and it was rather hard to identify him. 

 When I saw some Pine Siskins eating the dandelion seeds I ran back for my 

 camera, but while I was adjusting it they flew away. When I was dressing one 

 morning I heard a Wood Pewee and looking out of the window found him 

 perched on a telegraph wire. 



Forty different kinds of birds were seen in the garden between March and 

 August. — Richard M. Chase (age 12 years), Rochester, N. Y.
