oqo Merrill, Birds of Fort Sherman, Idaho. foct' 



* Podilymbus podiceps. — Common on the lake in spring and autumn. 

 Urinator imber. — Resident and quite common except in ^vintel•. 



* Larus argentatus smithsonianus. — Several taken on the lake during 

 fall and winter. 



* Larus delawarensis. — An adult taken January 6, and several young in 

 September; not rare during winter. I saw no Gulls on the lake during 

 summer. 



* Larus Philadelphia. — One taken and several seen in November. 



A small white Tern breeds about the lake, but I did not succeed in pro- 

 curing any specimens for positive identification. 



Phalacrocorax dilophus cincinatus. — Several Cormorants, probably of 

 this form, were seen on September 19. 



* Merganser americanus. — Common during fall and winter. 

 Merganser serrator. — A single specimen taken. 



* Lophodytes cucullatus. — The most abundant of the Mergansers, fre- 

 quenting especially the rivers, and in the autumn collecting in flocks of 

 forty and fifty individuals. 



Anas boschas. — The most common Duck in this vicinity, a few remain- 

 ing throughout the winter. 



Anas americana. — During the latter part of September this is one of 

 the most common Ducks in the marshes at the southern end of the lake. 



Anas carolinensis. — Qiiite common, especially during the migrations. 



Anas cyanoptera. — Rare. A female with several joung two or three 

 days old seen June 11. 



Spatula clypeata. — Common. Said to have been unusually abundant 

 in the autumn of 1S94. About twenty-five were seen about the fort on 

 June I ; they were mostly paired and had perhaps been driven out of the 

 St. Joseph marshes, where they breed, by the unusually high water. 



* Dafila acuta. — Common in migrations. 



* Aix sponsa. — Common summer visitor, especially abundant at the 

 southern end of the lake during the early autumn. 



* Aythya collaris. — Seems to be more common than the other 'Blue- 

 bills,' one or both of which occur, but were not certainl3' identified. 



* Clangula islandica. — Abundant throughout the Avinter. All the Golden- 

 eyes seen by me were of this species, although the other doubtless occurs. 



*Charitonetta albeola. — Common during winter. 



* Histrionicus histrionicus. — Rare, but occasionally taken on the St. 

 Joseph and Coeur dWlene Rivers. 



* Erismatura jamaicensis. — Not uncommon in spring and autumn. 

 Branta canadensis. — Common in spring, rare in autumn. The most 



abundant species of Goose, especially on the prairie and at the southern 

 end of the lake. I have seen them as early as February 22, although the 

 middle of March is the more usual time of their arrival. A few pairs 

 nest near the lake, but much less frequently than a few years ago, owing 

 to the increase of settlers. Verv few Geese are seen during the fall flight
