Far Eastern Curlew vs Eurasian Curlew

In short

The Far Eastern Curlew and Eurasian Curlew are large waders with long, down-curved bills, but the Far Eastern Curlew is notably larger and has a more pronounced bill curve. In the field, pay attention to the underwing pattern and bill length for reliable identification.

Identification tips

1. Underwing Pattern: Look for the barred underwings of the Far Eastern Curlew. 2. Bill Length and Curve: The Far Eastern Curlew has a longer and more curved bill. 3. Size: Note the overall larger size of the Far Eastern Curlew. 4. Range: Consider geographic location; the Far Eastern Curlew is more likely in East Asia. 5. Vocalization: Listen for the lower-pitched call of the Far Eastern Curlew.

Size

The Far Eastern Curlew is generally larger than the Eurasian Curlew, with a longer, more curved bill.

Plumage

The Far Eastern Curlew has a distinctive barred pattern on its underwings, while the Eurasian Curlew's underwings are more uniformly pale. Both species have mottled brown upperparts, but these differences in underwing pattern are key.

Behaviour

Both species exhibit similar foraging behaviors, probing mudflats and wetlands for invertebrates. Behavior is not a reliable differentiator.

Habitat

Both species inhabit coastal mudflats and wetlands, but the Far Eastern Curlew is more commonly found in East Asia, while the Eurasian Curlew has a broader range across Europe and Asia.

Voice

The calls of both species are similar, consisting of a series of bubbling notes, but the Far Eastern Curlew's call is generally lower-pitched and more resonant.
