This is not now one of the more couinion of the dneks. althon,i,'h 

 it may still be i)roi)erly designated common. There have been rej;- 

 nlar visitations of small s^ronps. composed of males and females, 

 the latter usually predominatin.u. to the Oberlin Water Works res- 

 ervoir since its establishment. In the marshes it is usually found 

 in the companies of Baldpates, where it can be readily distin- 

 guished by its color pattern. During the period of my studies at 

 Cedar I'oint I have never seen any large companies of this species. 

 The groups are more often composed of less than twenty individ- 

 uals than more. The earliest migration date is March 4, 1!»04, 

 and the latest spring record is April 23; the median spring arrival 

 is March 12. and the usual time of departure is near the middle of 

 April. My only fall record is October 21, 1907, when two were 

 seen.

My records indicate irregular occurrence, but there are doubtless 

 some individuals among the host of ducks in the marshes each mi- 

 gration season. Judging wholly from my own records I would call 

 this duck unconnnon and irregular. From April 13 to 20, 1903, 

 there were four males and one female on the Oberlin Water Works 

 reservoir, and on November 19 and 21 of the same year one vis- 

 ited the siinie place. Migrations seem to take jtlace at the same 

 time as the Redhead, and the birds seen liave usually been mem- 

 bers of the company of Baldpates. Redheads, etc. Fishermen and 

 hunters state that this is a fast disapiiearing species at the 

 marshes.

 spring, and latter part in fall. The spring migrations occur dur-
