The The black-and-chestnut, or Isidor's eagle (Spizaetus isidori) is a species of bird of the family Accipitridae, and found in dense, mountainous forests in South America. Persecution and habitat loss have reduced the numbers of this eagle severely.
Description
The black-and-chestnut eagle is large, with a length of 25 to 29 inches, and a wingspan of 58 to 65 inches. Females are slightly larger than males. Adult birds are black above, bearing a black crest on the head. The underside of the bird, including underwing linings, is a chestnut reddish-brown color, with the belly streaked in black. The underside of the wing flight feathers are light gray to white in color and tipped in black, as is the tail.
Range and habitat
This eagle is found in the tropical and subtropical mountainous slopes of South America, from northwestern Venezuela and northeastern Colombia, south to those regions of Equador, Peru, Bolivia, and northwestern Argentina which are part of the Andes mountain range. Its preference is dense montane cloud forest, where it is usually seen soaring above the canopy rather than perched.
Threats
The habitat in which this bird primarily lives - montane forests between 5,900-8,200 feet elevation - is currently under assault by human activity, either by land clearance for agriculture or logging and mining. As man has moved in and built structures, he has also moved in domestic livestock which has unintentionally provided a food source for the eagles, principally poultry; this in turn has led to a persecution of the eagles, with eight such cases reported in 2010. Populations in countries where they are known to still exist have been estimated to be no more than 250 individual birds per area, with an estimated total of 1,500 birds[2].
