Yesterday I saw two nestlings but couldn't see the egg. Today I was determined to learn if the unhatched egg was in fact a cowbird, which would convince me the nestlings were cowbirds. So I shooed the adult off the nest and removed the egg.*
It was just a stained vireo egg. What a relief! The big stains looked like a hole when it was in the darkness of the nest. I got to wondering when Kelly told me a vireo "does not have the capability to poke a hole in an egg." Thanks, Kelly, and sorry for leading you astray.
I saw a few interesting birds today, including this Olive-sided Flycatcher. At first I thought it was a juvenile with such a thick beak but I guess it's not.
And this flycatcher did not flick its tail, so I guess it's a Western Wood-Pewee. Not sure.
*UPDATE: Forgot to mention until a reader brought it to my attention. When I removed the dud egg one of the nestlings opened its gape and it was all yellow, not red like a cowbird's.
