The whimbrel (Numenius phaeopus) and the long-billed curlew (Numenius americanus) are two species of wading birds in the family Scolopacidae. Both species are large, with long legs and bills, and they are both found in coastal areas. However, there are some key differences between the two species.
One of the most noticeable differences between the whimbrel and the long-billed curlew is their size. The whimbrel is the smaller of the two species, with a body length of 42-50 cm and a wingspan of 80-95 cm. The long-billed curlew is larger, with a body length of 56-66 cm and a wingspan of 100-120 cm.
