- Accipiter bicolor
Identification
Adult birds have dark uppersides, plain gray undersides without any dark markings, and rufous thighs which can easily be hidden under gray belly feathers12. Juveniles are more variable showing undersides between white and rufous and less contrasting thighs, but always expected to have a neck collar similar in color to the underparts3.
A thread discussing differences between juveniles of this species and the Collared Forest Falcon is found here. Also frequently confused with various other Forest-Falcons and the Gray-bellied Goshawk.
Distribution
Mexico to Argentina and east to the Guianas and Brazil.
Taxonomy
The Chilean Hawk was recently split from Bicolored Hawk. Therefore, four subspecies remains: bicolor, fidens, pileatus, and guttifer4.
Habitat
Lowland and subtropical forests; also reaches the lower limit of the temperate zone around 2500 m.
Behaviour
It builds a stick nest; 1-3 eggs are laid and are incubated for 35 days; the young fledge 30-36 days later.
The diet includes birds.
