Species Description

It is 12.5 cm long, with a wingspan of 20-23 cm and a weight of 15-20 g. The male has a largely yellow-green head and underparts with a yellower forehead, face and supercilium. The lower belly and undertail-coverts are whitish and there are some dark streaks on the sides. The upperparts are grey-green with dark streaks and the rump is dull yellow. The female is similar to the male but duller with a greyer head and breast and less yellow underparts. Juvenile birds are largely brown with dark streaks.

It is about 10% larger, longer and less contrasted than its relative the Serin, and has more grey and brown in its plumage and relatively shorter wings.

The song is a silvery twittering similar to the songs of the Serin and Citril Finch.

Habitat

It occurs in a wide variety of habitats from pine and laurel forests to sand dunes. It is most common in semi-open areas with small trees such as orchards and copses. It frequently occurs in man-made habitats such as parks and gardens. It is found from sea-level up to at least 760 m in Madeira, 1100 m in the Azores and to above 1500 m in the Canary Islands.

Distribution

It is endemic to the Canary Islands, Azores and Madeira in the region known as Macaronesia in the eastern Atlantic Ocean. In the Canary Islands it is common on La Gomera, La Palma and El Hierro but more local on Gran Canaria and rare on Lanzarote and Fuerteventura where it has only recently begun breeding. It is common in Madeira including Porto Santo and the Desertas Islands and has been recorded on the Salvage Islands. In the Azores it is common on all islands. The population has been estimated at 80,000-90,000 pairs in the Canary Islands, 30,000-60,000 pairs in the Azores and 4,000-5,000 pairs in Madeira.
