The Western Red-tailed Hawk is common and very generally distributed 
throughout the Cape Region. Mr. Frazar found it at all seasons, but most 
numerously in late autumn, when there is probably an influx of birds which 
have bred further north. During the last two weeks of November a great 
many were seen about the lagoon at Santiago, where they were evidently 
attracted by the Coots (Fulica), on which they were preying. Some of them 
were very bold and easily shot. One pounced on a Quail (Lophortyx califor- 
nicus vallicola) which Mr. Frazar had just wounded and which lay fluttering 
on the ground within fifteen yards of the spot where he was standing. 
Mr. Bryant saw the Western Red-tail at Santa Margarita Island in January 
and February, 1888; at Ubi on May 9, 1889; and at San Fernando (no date 
given). Mr. Anthony says that it is ““very common throughout the northern 
part of the peninsula,” and that he found it “nesting in abundance in the 
pines on San Pedro [Martir].”? Its general range along the Pacific slope 
extends from Alaska southward into Mexico.

Mr. Belding mentions this species as “ very rare.” Mr. Frazar obtained no 
specimens, but on four different occasions at San José del Cabo, and once at 
Santiago he saw “a perfectly black Hawk having a narrow white band across
