The diet of tyrant flycatchers consists mainly of arthropods and fruits (Sherry 1984). The most common foraging technique used by the Social Flycatcher is the sally strike (Gabriel and Marco 2005). In addition to the use of the sally strike, the Social Flycatcher also uses the sally glide, hover and pounce (Gabriel and Marco 2005). Gabriel and Marco found that the Social Flycatcher generally attacks its prey from a perch 3m or higher from the ground (2005). They also noted that the Social Flycatcher normally attacks its prey from a distance of 3-4m (Gabriel and Marco 2005).
Social Flycatchers have also been known to feed on other types of insects, tadpoles, arillate seeds, small berries, and other fruits (del Hoyo et al. 2004). The Social Flycatcher feeds at all levels, gathering fruit and picking berries either from a perched position or taken in flight (Stiles and Skutch 1989). Large groups gather at fruiting trees (del Hoyo et al. 2004). They frequently perch in open fields on tall trees, generally at mid-level, and secure insect prey via long aerial sallies or short sallies to vegetation (del Hoyo et al. 2004). Social Flycatchers forage most frequently in large, vocal groups as well as alone and in pairs (Restall et al. 2006).
