Dark-sided Thrush vs Purple Cochoa

In short

The Dark-sided Thrush and Purple Cochoa can be distinguished primarily by their plumage: the thrush is brown with dark streaks, while the cochoa has a distinctive purple sheen. Both species belong to the same family but differ significantly in coloration and habitat preferences.

Identification tips

• Look for the dark streaks on the underparts of the Dark-sided Thrush versus the purple sheen of the Purple Cochoa.
• Observe behavior: ground foraging suggests a thrush, while canopy activity suggests a cochoa.
• Consider habitat: dense undergrowth for the thrush, higher canopy for the cochoa.

Size

Both species are similar in size, typical of medium-sized thrushes.

Plumage

The Dark-sided Thrush has a brown body with dark streaks on the underparts, providing a camouflaged appearance. In contrast, the Purple Cochoa is notable for its iridescent purple plumage with a greenish-blue head and back, making it much more vibrant and distinctive.

Behaviour

The Dark-sided Thrush is often seen foraging on the ground or in low vegetation, while the Purple Cochoa is more arboreal, typically found in the canopy.

Habitat

The Dark-sided Thrush prefers dense forest undergrowth, often in montane regions. The Purple Cochoa, however, is usually found in higher elevation forests, often in the canopy.

Voice

The vocalizations of these species are not well-documented for field identification, but the Purple Cochoa is generally quieter and less vocal than many thrushes.
