Slender-billed curlew

(Numenius tenuirostris)

Description

The slender-billed curlew is a small curlew,36–41 cm in length with a 77–88 cm wingspan.It is therefore about the same size as a whimbrel,but it is more like the Eurasian curlew in plumage.The breeding adult is mainly greyish brown above,with a whitish rump and lower back.The underparts are whitish,heavily streaked with dark brown.The flanks have round or heart-shaped spots.The non-breeding plumage is similar,but with fewer flank spots.Male and female are alike in plumage,but females are longer-billed than males,an adaptation in curlew species that eliminates direct competition for food between the sexes.The juvenile plumage is very similar to the adult,but the flank are marked with brown streaking,the heart-shaped spots only appearing toward the end of the first winter.
