26 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 134 
The two adult females shot at Salinas January 23 and 28 have 
the following measurements: Wing 357, 305; tail 210, 206; culmen 
from cere 27.4, 26.6; tarsus 89.8, 86.2 mm. 
Family PANDIONIDAE: Ospreys 
PANDION HALIAETUS CAROLINENSIS (Gmelin): Osprey, 
Aguila Pescadora 
Falco carolinensis GMELIN, Systema naturae, vol. 1, pt. 1, 1788, p. 263. (South 
Carolina.) 
Ospreys were observed daily along the shore, usually alone, but 
occasionally two in sight at the same time. One was recorded carry- 
ing a fish at Isla Rancheria February 4. 
Family FatconipaE: Falcons 
FALCO PEREGRINUS ANATUM Bonaparte: Peregrine Falcon, 
Halcon Cazapatos 
Falco Anatum Bonaparte, Geographical and comparative list of the birds of 
Europe and North America, 1838, p. 4. (Egg Harbor, N. J.) 
Peregrines were observed occasionally but appeared to be casual in 
occurrence. On the afternoon of January 21 a large one, evidently 
a female, dropped on a laughing gull resting on the beach in front of 
the guardhouse, crippled it, and then began to circle over it. The tide 
was out, exposing a broad expanse of sand and rock, and presently 
the falcon alighted briefly at the edge of the water. Apparently it was 
not hungry, as, though it returned several times, it did not pick up 
the gull. While it seemed to pay little attention to the crowd of men 
watching, it was careful not to come within gun range. 
FALCO ALBIGULARIS ALBIGULARIS Daudin: Bat Falcon, 
Halcon Cazamurciélagos 
Falco albigularis Dauvtn, Traité élémentaire et complet d’ornithologie, vol. 2, 
1800, p. 131. (Cayenne.) 
January 13 I shot the female of a pair flying about at the edge of 
the forest back of the pastures at Punta Damas. Ten days later one 
soared in rising air thermals in company with several vultures near 
the shore at Salinas. Another was recorded at Punta Damas Janu- 
ary 26. These falcons are graceful on the wing and soar regularly, 
evidently for pleasure. At rest they perch on dead branches or stubs 
where they have a clear view. Small birds in their haunts seem to 
continue their activities without fear while the falcons are about.
