Wood-Pewee singing at the top of Chew’s Ridge, elevation 5, 082 ft.
Western Wood-Pewee (Contopus sordidulus) is a migratory, insect-eating bird in the Tyrant Flycatchers (Tyrannidae) family. This "grayish-brown flycatcher is found in deciduous and mixed forests and edges. Nondescript overall with two pale wingbars; bill is usually mostly dark with only limited orange at the base. Note very long wings and larger size than Empidonax flycatchers. Typically seen on a high perch, occasionally sallying out to snatch an insect. Essentially identical to Eastern Wood-Pewee; averages darker overall with weaker upper wingbar, but reliably distinguished only by voice. Listen for buzzy tones, especially the “BREeerr” song."
