The nest, built by the female, is an open saucer of sticks. The typical clutch is two or three whitish eggs heavily blotched with brown. These are incubated mostly by the female for 17–18 days with a further 24 days to fledging.
Adult boat-billed flycatchers are one of the largest species of tyrant flycatcher, measuring 23 cm (9.1 in) long and weighing 70 g (2.5 oz). The head is black with a strong white eyestripe and a concealed yellow crown stripe. The upperparts are olive-brown, and the wings and tail are brown with only faint rufous fringes. The underparts are yellow and the throat is white.
The massive black bill, which gives this species its English and generic names, is the best distinction from the similar great kiskadee, which also has more rufous tail and wings, and lacks the olive tone to the upperparts. The call is a strident trilled nya, nya, nya.
