Grey-crowned Goldfinch

The grey-crowned goldfinch is 10.5–14 cm (4.1–5.5 in) long with a wingspan of 21.5–25.5 cm (8.5–10.0 in). They weigh about 15–21 g (0.53–0.74 oz). The male has a brighter and more extensive red on the face and brighter yellow on the wing than the female, which appears to be the only notable difference between the sexes. Both sexes have a pinkish bill. The juvenile lacks the red in the face, has faint streaking on breast and has buffish tips to coverts and tertial markings. The juvenile has duller and darker legs compared to the adult's pink to dull brown legs. Voice: The song of the grey-crowned goldfinch is a rather chaffinch-like combination, with a long mix of pleasant bubbling and twittering, though it lacks the "tinkling" notes of the European goldfinch. Its calls include twittering "deedelit" and "chirik", which do have a similar tinkling sound.
