Planalto Woodcreeper vs Lesser Woodcreeper

In short

The Planalto Woodcreeper (Dendrocolaptes platyrostris) and Lesser Woodcreeper (Xiphorhynchus fuscus) can be distinguished by their size and bill shape. The Planalto is larger with a heavier, more robust bill, while the Lesser is smaller with a more slender, slightly curved bill. Both species are found in similar habitats, but their foraging behavior and vocalizations can also help in identification.

Identification tips

1. Size and Structure: Look for the larger size and heavier bill of the Planalto Woodcreeper. 2. Plumage: Note the more extensive streaking and spotted crown of the Lesser Woodcreeper. 3. Behavior: Observe foraging behavior; Lesser prefers rough-barked trees. 4. Vocalizations: Pay attention to any differences in calls if possible.

Size

Planalto Woodcreeper is larger and more robust compared to the smaller, more slender Lesser Woodcreeper.

Plumage

Planalto has a more uniform brown plumage, while Lesser Woodcreeper shows more extensive streaking on the mantle and a spotted crown, with a buffier underside.

Behaviour

Planalto Woodcreeper is less associated with ant swarms than previously thought, while Lesser Woodcreeper forages on rough-barked trees, focusing on arthropods.

Habitat

Both species inhabit similar forested areas, but Lesser Woodcreeper is more common and widespread.

Voice

Specific vocal differences are not detailed, but listening for variations in calls could aid identification.
