iy eae MERRILL, Birds of Fort Sherman, Idaho. 353 
*Archibuteo lagopus sancti-johannis. — Occasionally seen in early 
spring and late autumn. 
Aquila chrysaétos.— Occurs sparingly throughout the year. 
Halizetus leucocephalus.— A few pairs breed about the lake. An adult 
seen on February 5. 
Falco mexicanus.— Rare; taken in September. 
* Falco richardsonii.— Of a male taken August 20 Mr. Brewster remarks : 
‘“This specimen is unusually dark and richly colored,” but the wing mark- 
ings were typical of the species. A young female was taken October 1. 
Falco sparverius deserticolus.— The Sparrow Hawk arrives early in 
April and is common by the 15th-20th; breeds. With the exception of 
this species and the Goshawk and Osprey, Hawks are remarkably scarce 
about Fort Sherman, although apparently there is an abundant supply of 
food at all seasons. 
Pandion haliaétus carolinensis.— First observed April 25 and frequently 
seen thereafter during the summer. 
Asio wilsonianus.— A single specimen examined. 
Asio accipitrinus.— This Owl is frequently flushed on the prairie and 
marshes in the autumn. 
*Nyctala tengmalmi richardsoni.— Two fine specimens are in Mr. 
Shallis’s local collection which were taken early in the spring of 1894 on 
the prairie about seven miles from the fort. These, and a third specimen 
brought to him some years ago, are the only ones Mr. Shallis has seen. 
* Nyctala acadica——A specimen taken January 19; its stomach con- 
tained two Hesferomys. During the spring its notes are frequently heard 
at night in the deep woods bordering the lake. 
Megascops asio swbsp.?— Screech Owls were occasionally heard in and 
about the fort, doubtless the macfarlanez form. They were quite rare; 
apparently. 
Bubo virginianus subarcticus. 
Bubo virginianus saturatus.— Both forms of the Great-horned Owl 
occur here commonly, and, judging from the specimens I have examined, 
in about equal numbers. 
Nyctea nyctea—— Not uncommon in some winters, but irregular and 
uncertain. In December, 1896, there was a general migration of Snowy 
Owls into northern Idaho, Oregon and Washington and dozens were 
killed. 
* Glaucidium gnoma,— Not uncommon and a resident. 
* Coccyzus americanus occidentalis.— One seen July 30, 1895. 
Ceryle alcyon.—_ Common during summer. A few pass the winter but 
most return from the South about the middle of April. 
Dryobates villosus hyloscopus.— Abundant during winter, and more 
often seen at that season than all other Woodpeckers combined. Females 
were more common than males in the proportion of at least four or five to 
one. A series of specimens are of greater size than the usual average of 
45
