The crested caracara
Caracara cheriway (Falconidae) is a medium-sized raptor (1050-1300 g), with a range from the southernmost United States, central and southern Florida, southern Texas, southern Arizona, Baja California Peninsula through Mexico and Central and South America (Morrison & Dwyer 2012).
In Florida, NRCS used ACEP funds to enroll an additional 6,700 acres in the Northern Everglades Watershed, supporting the restoration and protection of habitat for a variety of listed species, including the Wood Stork, Crested caracara
, and Eastern Indigo Snake.
After Cape Horn came a landing at Wulaia Bay, where we saw birds of prey like the great crested caracara
, and tasted wild calafate berries, just as Darwin would have done when he visited this remote spot in 1833.
The Crested Caracara
is a fairly common resident in Sonora below 1000 m elevation, including a rather isolated modern record near Terapa (Fig.
Just two weeks ago, he scurried to Hansen Dam to ogle a crested caracara
, an orange-faced South American falcon rare to California.
Unfortunately, the crested caracara
is threatened as its habitat falls victim to Florida's rapid urban and agricultural development.
Six avian taxa on the list, however, are represented in the United States only by peripheral populations when the entire range of the species is considered: Masked Bobwhite (Colinus virginianus ridgwayi), Audubon's Crested Caracara
(Polyborus plancus audubonii), Northern Aplomado Falcon (Falco femoralis septentrionalis), Thick-billed parrot (Rhynchopsitta pachyrhyncha), Cactus Ferruginous Pygmy-Owl (Glaucidium brasilianum cactorum), and Wood Stork (Mycteria americana).
By day they search for carrion over enormous areas, and are often guided by the movements of other smaller carrion-eating birds, such as the turkey vulture (Cathartes aura), or by those of birds of prey, such as the crested caracara
Besides deer, we spotted Harris and white-tailed hawks and a crested caracara
Albinism in the Crested Caracara
and other raptors in Baja California Sur, Mexico.
