Transformation of Plumage
A Golden-crowned Sparrow appeared in a local park back in November and stayed through the winter until it left sometime around second half of April. This gave an opportunity to study how the bird plumage changed over the months from basic to breeding. Here's a composite of two photos, the one on the left was taken on Nov 21 2021, whereas the second on the right was taken on April 17, 2022. The faint yellow on its crown transformed into bright yellow with black marking around the eyebrow, giving it a full adult breeding plumage. Scarborough Heights Park, Toronto, Ontario.
