The Caracara is a resident species and is generally distributed and abundant, 

 especially in the low country 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 Jose del Rancho. On November 4, at San Jose 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 Yiscaino 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.

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 alon^ 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.
