Turquoise Tanager vs White-bellied Tanager

In short

The Turquoise Tanager (Tangara mexicana) and White-bellied Tanager (Tangara brasiliensis) can be tricky to differentiate due to their similar size and overlapping ranges. Key differences lie in their plumage, particularly the underparts and back coloration. Observing these features carefully will aid in accurate identification.

Identification tips

1. Look for the white belly of the White-bellied Tanager, which contrasts with its darker upperparts. 2. Note the darker blue back of the Turquoise Tanager, which is more uniform. 3. Observe in good light to accurately assess plumage coloration. 4. Consider the habitat and geographic location, as the White-bellied Tanager is more region-specific.

Size

Both species are similar in size, typical of small tanagers, making size an unreliable distinguishing feature.

Plumage

The Turquoise Tanager typically has a darker blue back with a more uniform appearance and lacks the white belly seen in the White-bellied Tanager. The White-bellied Tanager is notable for its white underparts and a more contrasting appearance with its darker upperparts.

Behaviour

Both species exhibit typical tanager behavior, often seen in mixed-species flocks and foraging actively in the canopy.

Habitat

Both species inhabit tropical forests, but the Turquoise Tanager is more widespread across a variety of forest types, while the White-bellied Tanager is more localized to specific regions.

Voice

Vocalizations are not well-documented for distinguishing these species, and both have typical tanager calls that are not easily differentiated in the field.
