Ecology and Life History

Short General Description

A bird (flycatcher, kingbird).

Migration

false - false - true - Arrives in nesting areas April-May (Terres 1980). Migrates through Costa Rica from late August or early September to late October and late March to mid-May (Stiles and Skutch 1989). Present in Colombia mainly early September-late October, and early March-early May; migrates in groups, sometimes many hundreds, infrequently alone (Hilty and Brown 1986, Ridgely and Gwynne 1989). Arrives in southeastern Peru in late September (Keast and Morton 1980).

Food Comments

Eats mainly insects obtained by flycatching from perch; also eats seeds and small fruits, and may pick food from ground or water surface (Terres 1980). Migrants in Costa Rica hawk insects and eat berries or arillate seeds (Stiles and Skutch 1989). Migrants in Panama often feed in flocks on fruit in forest canopy (Ridgely and Gwynne 1989).

Reproduction Comments

Clutch size 3-5 eggs. Incubation 12-13 days or perhaps longer, by female. Young tended by both parents, leave nest at about 13-14 days; parents continue to feed young for up to 5 weeks more.

Ecology Comments

Mean size of 4 territories in South Carolina during nestling period was 8.4 hectares (Odum and Keunzler 1955, cited in Murphy 1996). However, territories tend to be larger earlier in the nesting cycle (Odum and Keunzler 1955).
