This type of habitat not present above timber-line on upper Chitina 
on any of mountain slopes visited and doubtless explains absence of species. 
Possible, however, that they could have been found on southern or cold 
side of valley . 
21. Lagopus rupestris (Gmelin) Rock Ptarmigan 
On the return journey, August 20, as a bare, high, alpine ridge was 
traversed — divide between Calamity creek and the Nizina — elevation 
estimated at 5,500 feet, two coveys of ptarmigan routed. These birds 
plainly not willlow ptarmigan and Taylor, who knew them well locally, 
declared them rock ptarmigan. He further insisted that a smaller, white- 
tailed species to be found in some high parts of region, but none seen on 
present journey. 
22. Lagopus leucurus White-tailed Ptarmigan 
A specimen in full, white, winter plumage is in collection of Hoyea Lloyd — McCarthy, 
Alaska, November, 1922. 
23. Circus hudsonicus (Linnaeus) Marsh Hawk 
A hawk seen August 12 at a distance winging high up valley thought 
to be a migrant of this species. 
24. Accipiter velox (Wilson) Sharp-shinned Hawk 
Several times during summer a sharp-shinned hawk noted in flight 
over a stretch of very broken and rugged country some distance up valley, 
beyond foot of moraine. Definitely identified June 20, when seen fairly 
close and its shrill voice heard. Probably nested. 
25. Astur atricapilhis (Wilson) Goshaw t k 
First met May 12 in woods along Young creek when an adult seen 
with a burden in its talons, supposedly a red squirrel. Several times 
during spring and early summer goshawks seen near Kubrick's camp. On 
June 12 a brown- coated bird of previous year met in woods. This bird 
was sweeping through spruces at a tremendous pace, flying low, evidently 
bent on surprising red squirrel or rabbit or other prey. On May 29 two 
large hawks studied through field-glasses doing mock battle in air. 
Smaller of tw r o appeared to be a goshawk and badgering what seemed to 
be a large, grey falcon. The two clutcled talons, swmng each other in 
air, and exercised several thrilling manoeuvres. Cut of birds differ- 
ent, more spreading tail of smaller oird being plainly noticeable. When 
they separated, larger hawk winged off high, aiming across valley into 
w r hite slopes above timber. As a guess at identity it might be suggested 
that a goshawk was worrying a gyrfalcon. 
A beautiful male met near timber-line June 23 suggested a nest, but 
it was not until July 15 this was discovered, when the shrill cries of three 
young shouting “ Qua !” or “ Kea !”- — a more unmusical call scarcely can be 
imagined — led to its discovery. At river-level half a mile from camp. 
Young at this time had left the nest, but w r ere holding to vicinity, and 
very noisy. Male and young secured, but no female could be discovered 
by any artifice — even though one of young was left at nest site for several 
days. Bird kept in camp some time for study, but proved a most un- 
tractable and unrelenting dependent.
