Description and ecology

This bird occurs in a wide variety of habitats including pastures, riparian forests, and open residential areas with scattered trees. Its breeding range is from central Mexico to central Argentina. In most of this range it is usually found year-round, but in the southern parts of its range it retreats northward for the winter. This species is also known to wander widely. It occurs almost annually in the eastern United States seaboard and Canada.

This flycatcher builds a shallow cup nest 1–10 m (3.3–32.8 ft) high in a shrub or short tree. Females normally lay two or three eggs.

The fork-tailed flycatcher is white below, gray above, and has a black cap. Males sometimes show a yellow crown stripe. Males also have an extremely long forked tail, of even greater length than that of their cousin, the scissor-tailed flycatcher. Females have a somewhat shorter tail, while it is significantly shorter in juveniles. Males are 37–41 cm (15–16 in) in length; females, 28–30 cm (11–12 in), including tail. They weigh only 28–32 g (0.99–1.13 oz), much less than closely related kingbirds, which are half the total length of this species. The tail in adult males is 2–3 times longer than the length of the bird from the bill to the base of the tail.

This species is primarily an insectivore, but will switch to berries and small fruits during winter if insects become scarce.

gollark: But at most points I don't think most people went around getting to decide on exactly what their values were and building societies to best embody them.
gollark: It's probably some complex bidirectional thing.
gollark: If your ethical system is "the greatest good is maximizing the number of paperclips in existence", it's entirely sensible to try and overthrow existing society to make paperclips.
gollark: Also, guess what, "still logical to agree with" implicitly assumes some values again!
gollark: I go around somewhat disagreeing with older ethical systems, and society hasn't collapsed yet.
