. Once the persistence of the flycatchers has driven the rightful owners away, their eggs are removed, and the female flycatcher lays up to four, but usually two, black-streaked brown eggs. She incubates these on her own for 16 days to hatching, with a further 18–20 days to fledging.

Description

The adult piratic flycatcher is 15 cm long and weighs 23 g. The upperparts are unstreaked plain brown, although the flight feathers have narrow white edges. The head has a long whitish supercilium, a concealed yellow crown stripe, and a dusky mask through the eyes. The throat is white, and there is a white malar stripe. The underparts are whitish with touches of light yellow, besides blurred brownish streaking on the breast and flanks. The dark bill is short and broad. The call is an upslurred ''weeEEE'' given from a high perch for long periods of the day, or sometimes a monotonous ''weep weep weep''. Piratic flycatchers wait on an exposed perch high in a tree, occasionally sallying out to feed on
