polyborus plancus


MEASUREMENTS: The Crested Caracara has a body length of 19 - 23 inches, a 4-foot wingspan, and weighs 1 3/4 - 3 1/2 pounds.
The bird’s weight varies greatly depending on where it lives.
HABITAT: The Crested Caracaras’ preferred habitat is open, lowland countryside, like pastures, savannas, river edges, and ranches.
They may also be found in some forests and marshes.
These birds reside in the southwestern United States and Florida, Central America, and South America.
DIET: The Crested Caracara usually feeds on carrion, but they will take advantage of any food opportunity by eating small mammals, amphibians, reptiles, turtles, fish, crab, eggs, insects, worms, and nestling birds.
Caracaras hunt live food on the ground or take food from other birds.
REPRODUCTION: Crested Caracaras build a massive stick nest in a palm, cactus, tree, or on the ground. The female usually lays 2 - 3 eggs
that are incubated for 28 - 32 days. The young caracaras have a drawn out fledging period, taking up to 3 months before they are flying as independent birds.
NAME DERIVATION: The scientific name comes from poly, the Greek word for many or varied; boros, meaning gluttonous and remarks on the bird’s voracious appetite; and from the Latin word plancus, which is a word Aristotle used for an eagle.
The common name, caracara, is what South Americans called the bird and probably imitates the sound of the bird.
This bird has been called Caracara Eagle, King Buzzard, Mexican Eagle, Audubon’s Caracara
and Mexican Buzzard.
The scientific name of this bird was formerly Caracara cheriway.
INTERESTING FACTS:
-Unlike other members of the falcon family that do
not construct nests, the caracara builds a stick nest.
-The caracara is the most terrestrial bird in the falcon group.
It spends a great deal of time on the ground.
