The Caracara is a resident species and is generally distributed and abundant, 
especially in the low couutry bordering the Gulf. Mr. Frazar notes it as 
paired and apparently breeding in January at La Paz, but he saw no nests 
until July 26, when one containing two chicks only a few hours old was found 
at San José del Rancho. On November 4, at San José del Cabo, he saw two 
Caracaras swoop at a slightly wounded Coot (Fulica) which was fluttering 
over a mud flat. Alighting they pursued it on foot, but although they evi- 
dently tried their best to overtake and capture it, it finally got to the water, 
when they gave up the chase and, after watching it awhile, flew off. 
Mr. Bryant says that this species is “not often seen north of latitude 26°,” 
but “two were said to have hung around a beach camp at Santo Domingo, on 
San Sebastian Viscaino Bay, north of lat. 28°.’ This probably represents 
about the extreme northern limit of the Caracara’s range on the Pacific coast. 
To the southward it is found as far as Darien.

AMERICAN OSPREY. 
Pandion haliaétus carolinensis BeLp1ne, Proc. U. 8. Nat. Mus., V. 1883, 543 (Cape 
Region), 547 (San José). Bryant, Proce. Calif. Acad. Sci., 2d ser., II. 1889, 
283 (Cape Region). Brnpire, Life Hist. N. Amer. Birds, pt. I. 1892, 324 
(measurements of egg from Cape St. Lucas, largest of 69 specimens, 68.5 
by 49.5 mm.). 
The Osprey is apparently resident and about equally numerous at all seasons, 
in the Cape Region. Mr. Frazar found a nest on Carmen Island, early in 
March, which contained a single freshly laid egg. 
On Santa Margarita Island Mr. Bryant “ counted a dozen nests, January 19, 
1888, upon five of which were one or two birds,” but the “ nests upon which 
the birds were seen” on the date just mentioned “ were without eggs on Feb- 
ruary 18,” although two fresh eggs were taken on this island on January 25. 
In the northern part of the Peninsula Mr. Anthony considers this species 
“abundant on all of the coast islands, and of less common occurrence along the 
coast’ itself (Bryant). 
The range of the Osprey on the Pacific coast extends from Panama to 
Alaska. It is known to breed as far south as the Tres Marias Islands.
