Lined Forest-Falcon Micrastur gilvicollis

Fierce-looking raptor of lowland rainforest interior east of the Andes; also ranges up into the foothills in a few areas. Gray with dense barring from throat to breast and an orange face (yellow in younger birds). Similar to Barred Forest-Falcon but usually has a darker orange face and little or no barring on lower underparts. Stays inside forest and is heard far more often than seen. Call is two or three nasal honks, repeated every few seconds.
