debelokljuni sjemenar Nesospiza wilkinsi

A chunky olive-yellow finch with a hefty grosbeak-like bill. Male typically has a paler base to the bill and female is smaller, duller, and streakier. Uncommon, preferring wooded portions of Nightingale Island, to which it is endemic. Sings a repeated “whut-preeu,” deeper and slower than the song of Nightingale Island Finch; female answers with a whistle. The much smaller and commoner Nightingale Island Finch has a thinner, daintier bill than Wilkins’s and occurs throughout the island.
