64 THE AUDUBON BULLETIN 
good protection for dozens of small birds, who hopped among the willow- 
twigs, bathed repeatedly in the small stream below the willows, and 
explored its shores. Miss Newton and Mrs. Baldwin sat with me on a 
low bank opposite the willows, and listed species just about as fast as we 
could write. In three-quarters of an hour, from one spot, we listed these 
birds: Red-shouldered Hawk (soaring low, just above the tree-tops), 
Chimney Swift, Red-headed Woodpecker, Yellow-bellied Sapsucker, 
Downy Woodpecker, Crested Flycatcher, Blue Jay, Crow, Catbird, Robin, 
Wood Thrush, Olive-backed Thrush, Gray-cheeked Thrush, Black and 
White Warbler, Tennessee, Orange-crowned, Nashville, Yellow, Mag- 
nolia, Cape May, Black-throated Blue, Myrtle, Black-throated Green, 
Blackburnian, Chestnut-sided, Bay-breasted, and Palm Warblers, Oven- 
bird, Grinnell’s (?), and Louisiana Waterthrushes, Connecticut Warbler, 
Redstart, Baltimore Oriole, Bronzed Grackle, Scarlet “Tanager, Cardinal, 
Rose-breasted Grosbeak, Indigo Bunting, Eastern Goldfinch, and White- 
throated Sparrow—thirty-nine species in all, and of course many more 
individuals. 
The rest of these notes will be, not accounts of single days, but a 
resume of some of the interesting species listed near the Museum. 
An American Bittern, taken in the Skokie Valley, September 21, was 
brought to me. “The wrist of one wing had been hurt by a stone. I kept 
the bird nine days, until its wing was quite well; in that time it ate 4 dozen 
full-grown leopard frogs, 15 crayfish, 10 skinks, a number of small sun- 
fish, 6 young watersnakes, and a large number of earthworms. It absolutely 
refused toads, and took no chopped beef. All food was swallowed whole, 
and usually alive. The bird fought the cage very little and I would have 
kept it longer, had its appetite been more moderate. Wearing band 34- 
548010, it was freed October 1. 
We saw very few ducks on the Des Plaines River; one Mallard was 
observed April 15, a Green-wing Teal April 28, and female Lesser Scaups 
April 19 and 27. 
Hawks of several species were seen near the Museum, during migra- 
tion periods, a Sharp-shinned April 29 and May 8, a Cooper’s October 21, 
and Red-tails on April 14 and October 21. On this last date seven were 
seen at once above Thatcher Woods, slowly circling south. They were quite 
low, so that on the turns and against the gray and windy sky, the red tail 
could be clearly seen. At least four were adults. 
Red-shouldered Hawks were observed May 10, 12, 24, ard September 
16; Broad-winged Hawks April 28, May 19, May 24 (on this occasion 
three were seen at once, very close, flying near a group of us as we ate 
lunch, either playing or fighting with each other, and often giving voice to 
their Killdeer-like cry). 
Rough-legged Hawk May 19 (a late date for this hawk). We watched 
with 8-power glasses from just across the Des Plaines, seeing clearly the 
light head and breast, and the very dark band across the lower breast and
