The tyrant flycatchers belong to the family Tyrannidae. This is the largest family of birds in the entire world. It includes more than 400 different species. These birds live throughout North and South America. They are the most diverse bird family in almost every country in the Americas. The only exceptions are the United States and Canada.

Members of this family belong to the suborder Tyranni. These are known as suboscines. This means they lack the sophisticated vocal capabilities found in songbirds, or oscines. The family name comes from the naturalist Mark Catesby. In the 1730s, he described the eastern kingbird as "the tyrant." Later, Carl Linnaeus adopted this name for the whole family. Today, the family contains 441 species divided into 104 different genera.

Tyrant flycatchers show incredible variety in their physical appearance. Most species have plain colors like brown, gray, or white. This plumage often provides camouflage to help them hide. However, some species are very bright. The vermilion flycatcher is a striking red. Other species, like the many-colored rush-tyrant, show blue, black, white, and yellow. Some flycatchers have bright yellow underparts or erectile crests on their heads.

Their feeding habits are also quite diverse. Most species are insectivorous, meaning they eat insects. Many North American species use a "sallying" style. A bird flies from a perch to catch an insect in the air. It then returns immediately to the same perch. In the tropics, many species prefer to glean. This means they pick insects off of leaves or bark. Larger birds, such as the great kiskadee, may also eat fruit or small vertebrates like frogs.

Size variation within the family is extreme. The smallest members are the pygmy tyrants. The short-tailed pygmy tyrant and black-capped pygmy tyrant are among the smallest passerines on Earth. They are so tiny they often look like small balls or insects. On the other end of the scale is the great shrike-tyrant. Some birds, like the fork-tailed flycatcher, have very long tails. The fork-tailed flycatcher has the longest tail feathers of any bird relative to its size.

These birds live in almost every land habitat in the Americas. However, the number of species varies by location. Tropical lowland evergreen forests and montane evergreen forests have the highest diversity. In these forests, you can find up to 90 species. Other areas, like northern temperate grasslands, have much lower diversity. Some habitats might only host a single digit of species. The Atlantic Forest and the Chocó regions are particularly rich in species.

Conservation is an important issue for many species. While the northern beardless tyrannulet is protected by the Migratory Bird Treaty Act, others face risks. In Brazil, the Minas Gerais tyrannulet and Kaempfer's tody-tyrant are considered critically endangered. In 2007, seven species were listed as endangered and eighteen were listed as vulnerable. Protecting these diverse habitats is vital for their survival.
