Flycatchers are small to medium-sized birds belonging to the family Tyrannidae. They are known for their distinctive hunting technique, which involves catching insects in mid-air. These birds often perch on branches or wires, waiting for their prey to pass by before darting out to snatch it. There are over 400 species of flycatchers found worldwide, primarily in North America, South America, and Asia. They typically have a stout body, a broad head, and a short, square tail. Many species are also recognized for their varied and melodious songs, which they use to communicate and establish territory.
