Common Crossbill vs Two-barred Crossbill

In short

The Two-barred Crossbill (Loxia leucoptera) is best distinguished from the Common Crossbill (Loxia curvirostra) by its prominent white wing bars, which are absent in the Common Crossbill. Both species have similar body shapes and are specialized for extracting seeds from conifer cones, but their vocalizations and preferred habitats can differ.

Identification tips

1. Look for white wing bars on the Two-barred Crossbill. 2. Listen for the metallic, higher-pitched call of the Two-barred Crossbill. 3. Consider habitat: the Two-barred Crossbill is more associated with boreal forests. 4. Note that both species can appear similar in size and shape, so focus on wing bars and calls for reliable identification.

Size

Both species are similar in size, with robust bodies and strong bills adapted for conifer seed extraction.

Plumage

The Two-barred Crossbill has distinctive white wing bars that are absent in the Common Crossbill. Otherwise, both species exhibit similar plumage coloration, with males typically showing red or orange tones and females being more olive or yellowish.

Behaviour

Both species are nomadic and form flocks, often moving in response to conifer seed availability. They are adept at using their crossed bills to open cone scales.

Habitat

Voice

Vocalizations differ, with the Two-barred Crossbill having a more metallic and higher-pitched call compared to the Common Crossbill. However, vocal differences can be subtle and require careful listening.
