SIXTH ANNUAL REPORT. 157 



Helodromas solitarius ciniiaiuoiiieus, (Bre-ui'ster). 

 WESTERN SOLITARY SANDPIPER. 

 At our base camp several pairs were seen ; they were nesting. 



Actitis macularia, (Linn.). SPOTTED SANDPIPER. 



One seen at our base camp. I whistled to it, and it lighted on 

 the gtmwale of the boat. 



^g'ialitis sp.? PLOVER. 



On a flat in the river-bottom^ about thirty-five miles from its 

 mouth, we saw a pair of plovers about the size of Killdeer. They 

 were stouter, and had a black band across their breasts. 



Canacliites canadensis osgoodi, (Bishop). ALASKA 

 SPRUCE GROUSE. 

 During the latter part of April and May ist I found these 

 grouse not uncommon in the timber back of Tyonek. They 

 were not as tame as a person would expect; in fact, I found it 

 rather difficult to approach them before they took wing. No 

 flocks were seen, they evidently having mated. At our base camp 

 we saw several. One which an Indian killed, May loth, con- 

 tained large ovaries. 



Lag-opus leucurus, (Sz.mns & Rich.). NORTHERN 

 WHITE-TAILED PTAR^^IIGAN. 

 In the high mountains at our upper camp, about thirty-five 

 miles from the mouth of the river, White-tailed Ptarmigan were 

 common. They were found in pairs, and were very tame. I ap- 

 proached to within six feet of one and photographed it. 



Circus liudsonius, (Linn.). MARSH HAWK. 



Several were seen about Tyonek and the lowlands along Knik 

 River. One was noted May ist. 



Accipiter velox, (Wils.). SHARP-SHINNED HAWK. 

 Several were seen in the river-bottom. 



Hali?eetus leucocephalus alascanus, (Tozvn.). ALAS- 

 KA BALD EAGLE. 



Several seen at Tyonek and on the Knik River, where a pair 

 was nesting but a short distance from one of our camps.
