I went searching for migrant songbirds today at Paulik Park. I usually start off by standing near the hummingbird feeder, because while I listen to hear who is calling elsewhere in the park, it is likely one or more hummers will pop by. I heard an Anna's Hummingbird, but it was Rufous Hummingbirds (male and female) that came to the feeder.
And then this silent character appeared. At first I thought it was a Hammond's Flycatcher, one of those hard-to-identify Empidonax species, but it sat still, not flicking its wings and tail the way Empies are wont to do. The bird could have given a hint by calling, for song is often the best way to identify the species.
After checking guides and online images, I'm inclined to think that this bird is not an Empidonax, but rather a Western Wood-Pewee (Genus Contopus), based on its general appearance (sort of long, as opposed to somewhat scrunchy), the grey wash on the breast, smudgy grey on the undertail coverts (a bit hard to see), and absence of tail-flicking during several minutes of observation. It has a little more of what looks like an eye-ring than perhaps it should, but that too is difficult to see clearly. It was sitting three-quarters of the way up a maple just starting to flower, which is a typical pewee sort of perch.
Speak, bird, speak!
