Bald Eagle: Halicaetus leueoce phalus leu- 

 cocephalus. — No bald eagles were seen by us 

 in the park except the mounted specimen at 

 Lewis's, on Lake McDonald. Mr. Stevenson 

 says he has seen only one or two adults in 

 the park, but that the birds are known to 

 nest on the rocky buttes out on the plain?, 

 east of the park. Mr. Bryant says the}' 

 also nest on the North Fork of the Flat- 

 head. In 1887 three or four adults were 

 seen by Dr. Grinnell in the St. Mary Lakes 

 regiQ^. 



As^^the bald eagle lives largely on fish, 

 taken dead or alive, Mr. Gird says they 

 class him with the vulture. As he said, "lie's not the hunter 

 the roj'al eagle is." 



Family FALCONID^: Falcons, etc. 



I*KAiRiE Falcon : Ilierofalco mexicanus. — 

 Near Kootenai Pass, as we rode along tlie 

 vertical wall of a mesalike mountain mass 

 suggestive of the homes of the prairie 

 falcon, high overhead we were much pleased 

 to see one of the small hawks fly out w^itli 

 its characteristic quick, hard wing beats. 

 It was the only one seen or heard of during 

 the summer, but in the fall of 1887 Dr. 

 Grinnell found it common on the plains 

 and about the Upper St. Mary Lake. When 

 seen near at hand, it may be known by its 

 pale clay brown upperparts, white collar 

 and underparts. 

 Duck Hawk : Rhynchodon peregrinus anatum. — One of the duck 



hawks, which rank next to the goshaAvk as fierce birds of prey, was 



seen by Dr. Grinnell in 1887, feeding on n 



female shoveller, on a bluff overlooking Red 



Eagle Creek during a blinding snowstorm. 

 Pigeon Hawk: Tinnunculus colvmbarlus 



colunibariuH. — The pigeon hawk — one of the 



small bird-catching hawks — was reported from 



the park by Mr. Bryant. 



Desert Sparrow Hawk: Cerchneis spar verm 



phalit^na. — The familiar rufous and brown 



sparrow hawk, which lives largely on grass- 

 hoppers and nests in a hole in a tree trunk. From BioiogicM survey. 



was seen a number of times in the park. An fig. 53.— pigeon hawk.
