Robust Woodpecker vs Crimson-crested Woodpecker

In short

The Robust Woodpecker and the Crimson-crested Woodpecker are both large woodpeckers with striking red heads, but they can be distinguished by plumage details and habitat preferences. The Robust Woodpecker has a more uniform red head and distinct facial markings, while the Crimson-crested features a wide white malar stripe and a unique 'V' pattern on its back. Habitat can also aid identification, as the Robust prefers dense, tall forests, whereas the Crimson-crested is found in more varied habitats.

Identification tips

1. Look for the wide white malar stripe and 'V' pattern on the back of the Crimson-crested Woodpecker. 2. Note the uniform red head and distinct facial markings of the Robust Woodpecker. 3. Consider habitat: dense, tall forests suggest Robust, while varied habitats may indicate Crimson-crested. 4. Listen for the drum pattern of the Crimson-crested, as the Robust's vocalizations are less known.

Size

Both species are large woodpeckers, but size is not a reliable distinguishing feature between them.

Plumage

The Robust Woodpecker has a virtually all-red head with pale and dark-barred underparts and largely black upperparts with a creamy-white rump and mantle. Males have a small white and black spot on the ear covers, while females have a more obvious pale stripe outlined in black from the bill base to behind the eyes. The Crimson-crested Woodpecker also has a red head but features a wide white malar stripe and white streaks on the back that converge into a 'V' pattern.

Behaviour

The Crimson-crested Woodpecker is often seen in pairs or family groups and can be quite noisy, while specific behavioral notes for the Robust Woodpecker are less documented.

Habitat

The Robust Woodpecker is found in humid forests with tall trees, primarily in lowlands and mountains of southern Brazil, eastern Paraguay, and northeast Argentina. The Crimson-crested Woodpecker inhabits a variety of habitats, from dense forests to forest edges and light woodlands.

Voice

The Crimson-crested Woodpecker's drum typically consists of 3-5 raps, but specific vocalization details for the Robust Woodpecker are not well-documented.
