Eastern Wood-Pewee

" The Eastern and Western Wood-Pewees are very difficult to tell apart visually. Their breeding ranges overlap in a very narrow zone in the Great Plains. Despite their similarity, no evidence has been found that the two species interbreed in that area.
One potential cause of their decline is the overpopulation of white-tailed deer in the Eastern forests. In areas with high deer density, the intermediate canopy is disturbed by browsing, affecting the foraging space of the flycatcher.
Though this bird sings throughout the day, listen for its ballads before dawn's light and well after sunset when this activity peaks.
A group of pewees are collectively known as a "dribble" and a "squirt" of pewees."
