Life History

Food

Sepia-capped Flycatcher is insectivorous, but the diet is relatively poorly known. In southeastern Peru, stomach contents (n = ?) included ants (Hymenoptera), orthopterans, planthoppers (Homoptera), beetles (Coleoptera), spiders, unidentified pupae, and shield-bugs (Pentatomidae) (Fitzpatrick 2004). The stomachs of two specimens from Panama were "crammed with fragments of butterfly remains" (Wetmore 1972). Sepia-capped Flycatcher also takes some small fruit (Stiles and Skutch 1989, Fitzpatrick 2004).

Behavior

Sepia-capped Flycatcher forages in the under- and midstory of forest; usually it is within 8 m of the ground (Fitzpatrick 2004). As is typical of other species of Leptopogon, Sepia-capped Flycatcher perches with an upright posture, and frequently flicks one wing rapidly open and shut (Stiles and Skutch 1989, Fitzpatrick 2004).

Sepia-capped Flycatcher captures prey with upward sallies and with hover-gleans directed to vegetation, or, less frequently, to air (Stiles and Skutch 1989, Fitzpatrick 1980, 2004).

Territoriality

Very little information. At one site in southeastern Peru, the density was estimated as 2.5 pairs/100 ha, with an estimated territory size of 3 ha (n = 2) (Terborgh et al. 1990). Thiollay (1994) estimated a density a similar density, 1-2 pairs/100 ha, at a site in French Guiana.

Social and interspecific behavior

Sepia-capped Flycatcher often associates with mixed species flocks (Hilty and Brown 1986, Howell and Webb 1995, Fitzpatrick 2004). Flock associated in southeastern Brazil include Black-goggled Tanager (Trichothraupis melanops), Golden-crowned Warbler (Basileuterus culicivorus), and Scaled Woodcreeper (Lepidocolaptes squamatus) (Maldonado-Coelho and Marini 2004).

Reproduction

Sepia-capped flycatcher builds a globular or elliptical pendant nest with a side entrance. It is composed of moss (both green and dry), stems, and grasses, lined with seed down. The nest is suspended from slender roots or similar structures beneath a rock or a log, in ravines or above streams. The clutch is two to three eggs, which are white and unmarked. Nests are reported from April-May in Mexico. There are no data on the incubation or nestling period. (Data on nests, eggs and timine of breeding is from Bertoni 1918, Moore 1944).

Populations and Demography

There is no information related to topics such as age at first breeding, life span and survivorship, dispersal, or population regulation for Sepia-capped Flycatcher.
