19. Dafila acutu (pintail). Given in 1881 list of Michener. 



20. Air upon.m (wood duck). Rather common on migrations and probablj- breeds 

 rarely. Barnard says, "Frequent:"' Warren, " Occasional," and Michener, " So far as I 

 have I)eeu informed, this is the only *i-ild duck that has deigned to ne.st and breed in this 

 county; unlike its kin, it prefers a hollow tree for a nesting place."' During the spring 

 of 1886 two broods of Wood Ducks were found in Chester comity. 



21. Aythya americana (redhead). "Occasional winter visitant." (Warren. (M.) 



22. Aythya valliftneria (canvass-back). Probably a casual visitor on the migra- 

 tions. (M.)

 small flocks in spring and fall.

 migrating. 



28. Clanijiila hyemalis (old-squaw). Occurs but rarely. (M.) 



29. Erimnatura ruhida (ruddy duck). I have known of several instances uf the 

 capture of this species in our county. " Rare," (B ); "Frequent," (W.) 



30. Branta canadensis (C-anada goose). Common in spring and fall flying on its 

 migrations, but rarely stops in our limits. 



31. Olor columbinnus (whistling swan). Rare migrant. Given by Michener in 

 later l^^t. Not given by B. or W. I have never seen it in Chester county. 



32. Tantalus loculator (wood ibis). A very rare sti'aggler. One specimen was 

 taken a number of years ago by the late Vincent Barnard. 



33. Botaurns lentiginoses (American bittern). Common in some parts of the coun- 

 try. M. gives it "resident; common." I have found no positive record of its nest hav- 

 ing been found, but specimens have been shot throughout the summer months. Warren 

 has a specimen taken December 8, 1879. 



34. Botaurvs exilis (least bittern). Given in Michener's later list. Not given by B. 

 or W. Probably of rare occurrence. 



35. Ardea herodias (great blue heron). Rather common in spring and fall as a mi- 

 grant; may breed, but I have never met with its nest nearer than the borders of the Dela- 

 ware river, twenty miles di.stant. 



36. Ardea egretta (great white egret). Of accidental occurrence. Given by Bar- 

 nard, who says "seldom found." Warren had a .specimen taken in adjoining county of 

 Lancaster. I have never .seen it here. 



37. Ai'dea candidissima (snowy heron). Rare; occurs as a straggler only. 



38. Ardea viresc£ns (green heron). An abundant summer resident; frequently 

 breeds in colonies of six to ten pairs; nest in trees and bushes, a few sticks loosely put 

 together sufficient to hold the three or four pale-blue eggs. Food, fish, frogs and insects 

 from mansh-land mainly. 



39. Nycticora.r ruivius (black-crowned night heron). Common in spring and fall; 

 probably breeds; nesting similar to that of green heron. 



40. Orus canadensis (little brown crane). Given by B. and M. Both these records 

 are based on the same occurrence, as I am informed, by the venerable Dr. Michener, 

 who tells me that about 1840 a flock of about five individuals passed along the west 

 branch of the White Clay creek, flying northward, and one was shot and mounted by 

 him. This bird was in the doctor's collection for years. Later it went to Swarthmore 

 college and perished in a fire a few years ago. 



41. Rnllas virgiaianus (Virginia I'ail). Breeds occasionally; two nests have been 

 taken within a mile of Kennett Square, one about 1878, by A.sher Palmer; the other by 

 some boys in 1883. Both nests were in swamps near streams. I have an egg in my col- 

 lection from the latter nest. 



42. Porzana Carolina (sora). Rather common migrant. 



43. Porzana noveboracensia (yellow rail). Given by Michener in his 1881 list. I 

 have never .seen this bird in our county.
