Even before the buds burst and the flowers bloom, birds give us a hint that spring is coming.  Some of them turn yellow.

* White-throated sparrows have boring faces in the winter but their lores turn bright yellow ahead of the breeding season. They’ll leave in March or early April for their breeding grounds in the northern U.S. and Canada.

* American goldfinches were brownish all winter but molt into yellow feathers in late winter. Even the females turn a subdued yellow as seen in the female on the left in Marcy’s photo.

* At this time of year European starlings become glossy and their beaks turn yellow.  The starling below is male because the base of his beak is blue (near his face).

There are other birds whose yellow facial skin becomes brighter in the spring.  Can you think of who that might be?  …
