The Panama tyrannulet or yellow-green tyrannulet is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is endemic to Panama.
Region
Central America
Typical Environment
Endemic to humid lowland and foothill forests of central and eastern Panama, primarily on the Caribbean slope. It favors mature forest edges, tall second growth, and riparian corridors, often working the outer foliage of midstory and canopy trees. The species is frequently encountered in mixed-species feeding flocks. It avoids heavily degraded habitats but tolerates semi-open forest edges and light gaps.
Altitude Range
Sea level to 1200 m
Climate Zone
Tropical
Ease of Keeping
Beginner friendly: 1/5
Also called the yellow-green tyrannulet, this is a tiny foliage-gleaning flycatcher found only in Panama. It stays high in the midstory to canopy, where its soft, high-pitched calls can be easier to detect than the bird itself. It often accompanies mixed-species flocks and can be mistaken for a small warbler due to its size and constant motion.
Temperament
active and somewhat inconspicuous
Flight Pattern
short rapid wingbeats with quick hops between foliage
Social Behavior
Usually seen singly, in pairs, or small family groups, and commonly joins mixed-species flocks. Pairs maintain small foraging territories and communicate with thin contact notes. Nesting is thought to involve a small, well-concealed cup or globular structure placed in dense foliage.
Migratory Pattern
Resident
Song Description
A thin, high-pitched series of tsee or see notes, sometimes delivered in a short, rising sequence. Calls are sibilant and can be easily overlooked among canopy insect sounds.
