Identification

Powered by Merlin

Very striking and long-tailed bright rusty cuckoo, widespread in tropical lowlands and locally up into foothills. No similar species in its Mexican and Central American range, but in the Amazon compare with Black-bellied Cuckoo. Occurs in a wide range of wooded and forest edge habitats. Mostly seen foraging stealthily at mid-upper levels in trees, where it can be surprisingly difficult to see. Often seen swooping across roads and eliciting a ‘wow’ reaction. Song a long series of woodpecker-like squeaky ‘week’ notes, but more frequently found by its two-note ‘pik-burr’ call.

Relative Size

Larger than a Yellow-billed Cuckoo and smaller than a Plain Chachalaca.

Regional Differences

Ornithologists recognize three Common Squirrel-Cuckoo subspecies groups: the “Middle American” group, found from eastern Mexico to northwestern Colombia; the “nigricrissa” group, stretching from western Colombia to northwestern Peru; and the widespread “Amazonian” group, occurring across much of South America (and not just the Amazon region). These groups differ mainly in size, plumage color, and undertail pattern.
