This bright yellow bird played hide-n-seek with me for about an hour before I got a clear glimpse of it(well, almost clear ... ;-)). I was flying some kites on 14th Jan, Sankranti, when I happened to spot this one on a tree.

The American Goldfinch is a granivore and adapted for the consumption of seedheads, with a conical beak to remove the seeds and agile feet to grip the stems of seedheads while feeding. It is a social bird, and will gather in large flocks while feeding and migrating.

Human activity has generally benefited the American Goldfinch. It is often found in residential areas, attracted to bird feeders installed by humans, which increases its survival rate in these areas. Deforestation by humans also creates open meadow areas which are the preferred habitat of the American Goldfinch.

The American Goldfinch is a small finch, 11–13 centimeters (4–5 in) in length, with a wingspan of 19–22 centimeters (7–9 in). It weighs between 11–20 grams (0.39–0.71 oz). The beak is small, conical, and pink for most of the year, but turns bright orange with the spring molt in both sexes.
