We always have nesting Pewees in our yard (Pullman, Wa) and plenty of
cowbirds in the spring. In 9 years, I've never seen the pewees feeding a
cowbird chick.

Subject: [Tweeters] Pewees and Cowbirds


Just returned from a long weekend camping trip in central Oregon.
Nothing too remarkable in the limited time I was able to escape from the
group to bird, except I observed a pair of Western Wood-Pewees feeding a
juvenile Brown-headed Cowbird. From a limited search on the internet
(e.g., Nesting Success of the Western Wood-Pewee in Colorado, Western
Birds, 28:110-112, 1997), it seems that only some tyrannid flycatchers
are parasitized by cowbirds while others, including the pewees, are much
less so. So, I was wondering if others have made similar observations.
