great blue heron, sharp-shinned hawk, marsh hawk, king rail, 

 woodcock, great-horned owl, nighthawk, red-breasted nut- 

 hatch, solitary vireo, yellow palm warbler, bay-breasted war- 

 bler, northern parula warbler, Nashville warbler, blue-winged 

 warbler, blue grosbeak, and Bachman sparrow. 



The nineteen species of most general distribution, as evi- 

 denced by the fact that they were observed by all the parties in 

 the field, may be listed as follows : turkey vulture, bob-white, 

 flicker, chimney swift, crested flycatcher, brown thrasher, cat- 

 bird, southern robin, wood thrush, house wren, tufted titmouse, 

 red-eyed vireo, yellow-breasted chat, scarlet tanager, cardinal, 

 chewink, song sparrow, chipping sparrow, and English spSr- 

 row. 



In addition, the following twelve others were noted by every 

 party except one : kingbird, Carolina wren, Carolina chickadee, 

 blue jay, southern crow, white-eyed vireo, American redstart, 

 Maryland yellow-throat, oven-bird, purple grackle, field spar- 

 row, and American goldfinch. 



An analysis of the various lists shows that a number of 

 species, in addition to those of usually special distribution, 

 such as water birds and shore birds, were confined on this 

 date largely or wholly to the valleys of the rivers and the 

 larger streams. Such species were : barn swallow, bank swal- 

 low, rough-winged swallow, American redstart, hooded war- 

 bler, Maryland yellow-throat, northern water-thrush, prairie 

 warbler, black-poll warbler, black-throated green warbler, 

 black-throated blue warbler, cardinal, song sparrow, and white- 

 throated sparrow. 



Two species which have been increasing in numbers about 

 Washington during the past few years were noted on this oc- 

 casion — the mockingbird, which was common, and the 

 migrant shrike, which was tolerably common. 



Of the rarer birds of the District of Columbia there were 

 found the king rail, red-bellied woodpecker, great horned owl, 

 Cape May warbler, blue-winged warbler. ^Bachman sparrow, 

 and Henslow sparrow.
