Eastern Phoebes and Eastern Kingbirds are both types of flycatchers. Eastern Phoebes are smaller and brown with a distinct song that repeats their name source. On the other hand, Eastern Kingbirds are larger, with black upperparts, a white-tipped tail, and a concealed patch of red on the crown. Their calls are also different: Eastern Kingbirds have high-pitched, chattering calls, while Eastern Phoebes sing their name.
