The Least Flycatcher is a small songbird belonging to the family Tyrannidae. It measures about 4.5 to 5.5 inches in length and has a distinctive olive-brown back with a pale yellow belly. This bird is commonly found in wooded areas across North America, especially during the breeding season. These flycatchers are known for their unique call, which sounds like "che-bek." They primarily feed on insects, catching them in mid-air. The Least Flycatcher migrates south for the winter, traveling to regions in Central America and Mexico to escape the cold.
