Geographic Range
Piratic Flycatchers, Legatus leucophaius, are most commonly found in Mexico and from northern Argentina to southern Brazil. They often migrate to Costa Rica between the months of January and February. Piratic Flycatchers overwinter in southern Brazil and Argentina between the months of September and March.
(Elizondo, 2000; Land, 1970)
Biogeographic Regions:
nearctic
(native
); neotropical
(native
).
Habitat
Piratic Flycatchers frequently occupy the semi-open country, cultivated areas with tall trees, and the forest edge. These birds are hard to observe since they remain high up in the trees. In Costa Rica, Piratic Flycatchers reside on secondary savannahs or coffee plantations.

Physical Description
(0.67 to 1.11 oz; avg. 0.92 oz)
(5.71 to 5.91 in; avg. 5.81 in)
Piratic Flycatchers range in length from 14.5 to 15 cm (5.7 to 5.9 in) and are about 26 g (.9 oz) in weight. Adult Piratic Flycatchers have a dark olive green or brown coloring with a semi-colored patch of yellow on their bodies and dusty colored cranial regions. These birds have wings with pale yellow edgings and slightly lighter colorings than the body. The tail of the Piratic Flycatchers are dark cinnamon, almost black in color. They have a whitish throat which ultimately turns yellow as it moves down toward the lower belly. Brown striping is evident on the breast. The bill of the Piratic Flycatchers are broad at the base and short in length. These flycatchers possess a whitish line above the eyes, along the lower part of the head. When young, the Piratic Flycatchers are similar in color, but have less streaking on their breasts and have lighter color edging on the wings.

Reproduction
February-August
Piratic Flycatchers breed between the months of February and August. They wait till other flycatchers construct their nests, then force them to abandon the area. These nests are located high up in trees. Piratic Flycatchers annoy their victims to the point of distraction, remove any remaining eggs that inhabit the nest, and utilize the nest for their needs. They annoy their victims by entering the nests numerous times during the day and bothering the birds. Piratic Flycatchers rarely attack their victims, but rather provoke fights. The nests which the Piratic Flycatchers inhabit are enclosed and have a dome shape to them. These birds frequently add leaves to the nests to aid in cushion and warmth.
Piratic Flycatchers usually lay 2 to 3 eggs at one time; occasionally up to as many as 4 eggs. The eggs are a dark brown color and have scattered black spots on them. Subtle black lines are also present on the larger end of the egg. The eggs range in size from 16 to 22.5 mm (.6 to .8 in.). Female Piratic Flycatchers incubate alone for a period of 15 to 16 days. After 18 to 20 days, the young Piratic Flycatchers leave the nest and begin a life of their own. From this point on, the young birds do not rely on their parents for food or shelter.
(Schmalz, 2001; Ffrench, 1973; Stiles and Skutch, 1989)
Key reproductive features:
iteroparous
; seasonal breeding
; gonochoric/gonochoristic/dioecious (sexes separate); sexual
; oviparous
.
When the young hatch, the female provides warmth for them and they are fed evenly by both parents.
Parental investment:
altricial
; male parental care
; female parental care
.
Behavior
Piratic Flycatchers exist high up in trees and are rarely visible to people. One or two are seen at a time in a specific area; they travel in pairs and are rarely ever alone while traveling or during breeding season. Male Piratic Flycatchers often sit in trees and sing songs during the heat of the day. (Elizondo, 2000; Stiles and Skutch, 1989)
Food Habits
Piratic Flycatchers are omnivores which feed mostly on insects. They gather berries that will later be used for nutritional purposes and feed on green catkins of Cecropia. The insect that Piratic Flycatchers mainly prey on are dragonflies. These birds wait on exposed tree limbs till they notice prey, then fly out to attack.
(Stiles and Skutch, 1989; Land, 1970)
Primary Diet:
omnivore
.
Animal Foods:
insects; terrestrial non-insect arthropods.
Plant Foods:
fruit; flowers.
Predation
Though little research has been conducted on the Piratic Flycatcher concerning predation, we can assume that small treee snakes and other species that live high up in the trees are its predators.
