I agree with Louise. In fact, here?s a photo from almost exactly a year ago, in Nisqually: I wonder if it could be the very same poor Yellow Warbler being taken advantage of by the very same cowbird parents?

(Also, while I?m posting anyway, I?ve got some new photos and reflections on nesting Pileated Woodpeckers on my Natural Presence blog<naturalpresencearts.com>.)

Cheers,

Wow, that is exactly what I saw, but with a Yellow Warbler. Thank you all who responded. I am now a little more educated.

Hi Terry,



Most likely your poor yellow warbler was feeding a juvenile cowbird. Cowbirds lay their eggs in the nests of warblers for preference. Here?s a link to a photo of a common yellowthroat feeding a cowbird baby, for comparison with what you saw.
