Ruffle-head, CInt)-itonetla albeola. — Frequently associated with the 

 preceding, and even bolder. Usually, as the last, in- mixed flocks, the 

 females outnumbering the males. 



Ruddy Duck, Rrisinatnra rubida. — November 13, 1897, April 23, 

 i8g8. I found them much like the Grebes — diving when alarmed and 

 loth to leave the water. 



Blue Goose, Chen cccndesccns. — October 28th, 1896, two were cap- 

 tured. They were not at all timid, and permitted a near approach. A very 

 rare occurrence for so large a bird and so small a body of- water. 



Canada Goose, Branta Cdnadensis. — Single individuals soar about 

 the reservoir nearly every spring. But one was ever known to light. 



Thus 13 out of the 23 species which have been found in the county 

 have visited this small and seemingly unfavorably situated body of 

 water at one time or another. 



To this list should be added the other "Water Birds," but they can 

 perhaps better wait until another time.

"SOME REMARKS ON THE BIRDS OF CHESTER 

 COUNTY, PENN."* 



Following the publication of the paper of which the above is the title, 

 I received several communications calling my attention to facts of which 

 I had previously been ignorant. In order that no one may be misled 

 through my misunderstanding of the true state of affairs, I make the fol- 

 lowing statements: 



ist. The responsibility of so many of the remarkable statements in 

 the "list" referred to, should not rest wholly on the shoulders of the os- 

 tensible author, whose experience had been limited to two or three years 

 of field work. 



2nd. Our local ornithologists seem very loth to adopt the records 

 given by my correspondent for the reason that memory is a very unsafe 

 thing to depend upon especially when one has collected in many parts of 

 the country. It is said that it is no uncommon thing for some men who 

 have collected in various places and whose intentions may be perfectly 

 honest, to get certain experiences mixed up in their memory and state 

 with great certainty that a kind was killed at such a time and place, 

 when the specimen they were thinking of was something quite different. 

 Unfortunately my correspondent cannot refer to his cabinets of skins and
