Cuco Oscuro Hierococcyx bocki

Large long-tailed cuckoo with a distinctly raptor-like appearance. As with most other hawk-cuckoos, often perches deep in tall trees; best detected by its song, a piercing and repetitive “wit-CHEW-WEE”. If seen well, note adult’s dark gray back, rufous chest, and barred white belly; juvenile has streaked throat and browner upperparts. Found in montane and foothill forest.
