i888.] Merrill 07i Birds of Fori Klamath, Oregon. lAI 



surrounded by water too deep to permit approach by wading. The only 

 nest I found was on a floating but almost submerged cow 'chip,' a rather 

 unusual place for a bird's nest; it was at the edge of a grassy pond in the 

 middle of which several Terns were nesting, and it had probablj' drifted to 

 where I found it. On the top of the 'chip,' a large one, were a few water- 

 soaked grass and tule stalks, and the lower half of the egg was wet, though 

 the bird was on it when found.* 



Phalacrocorax dilophus cincinatus .'' A Cormorant which I took to be- 

 long to this subspecies, but of which no specimens were obtained, was quite 

 common during summer on the lake and Williamson's River. Several 

 small flocks were also seen in August at Diamond Lake, the head of the 

 south fork of the Umpqua River, and about fifty miles north of the Fort. 



Pelecanus erythrorhynchos. Common on the lake, a part of which is 

 called Pelican Bay, from the abundance of these birds which breed on cer- 

 tain islands. 



Merganser americanus. 



Merganser serrator. Both of these species are quite numerous. 



Lophodytes cucullatus. Several pairs seen on the lake and in the 

 marsh; a resident species. 



Anas boschas. Very common at all seasons, breeding in great numbers 

 in the marshes and in suitable places along the streams. They begin to 

 lay late in March, but the middle and latter part of April is the usual time 

 for incubation to begin. So many nests are destroyed by the Indians, 

 who have an annual egging, by coyotes, and by high water, that fresh 

 eggs may be found until early in July. A nest found June 22 contained 

 eight eggs, out of each of which the duckling was beginning to break its 

 way, making a constant peeping noise. It is, perhaps, uncommon for so 

 many young to hatch at exactly the same time, though I was told that 

 this is often the case with Mallards and other Ducks. 



Anas strepera. Not common in winter nor during the migrations. A 

 pair was seen in the marsh on May 27, and from their actions doubtless 

 had a nest near b_y. 



Anas americana. Common during winter. 



Anas carolinensis. Common in winter, especially in the smaller 

 streams which are always open, even in the coldest weather. A few pairs 

 remain to breed. 



Anas cyanoptera. Early in May several flocks of this beautiful Teal 

 arrived, and before the end of the month it was common in the marsh, 

 mostly paired and not at all shy. As I waded about the shallow pools of 

 water which are their favorite resort, they would often allow me to 

 approach within a few feet. A nest found June 3 contained eight fresh 

 eggs, and was placed on a tussock of dry grass, the new green blades sur- 

 rounding it. When found the female was on the nest, which she left hur- 

 riedly; on my return later she had covered the eggs with dry grass stems 

 and blades, completely concealing both nest and eggs. Two nests found 



* A small white Tern, probably .S'. antillarum, was occasionally seen among the 

 Black Terns, but none were secured for positive identification.
