The grey-and-white tyrannulet is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Ecuador and Peru.
Region
Western Andes and Tumbesian region (Ecuador and northwest Peru)
Typical Environment
Occurs on the west Andean slopes and adjacent lowlands from southwestern Ecuador into northwestern Peru. Prefers forest edges, second growth, and semi-deciduous woodlands, often near riparian corridors. It forages mainly in the mid- to upper canopy but will descend to lower strata at forest edges and clearings. The species tolerates moderately disturbed habitats and can be found in agroforestry mosaics with remnant trees.
Altitude Range
0–1800 m

A small tyrant flycatcher of Ecuador and Peru, the grey-and-white tyrannulet is often overlooked as it forages high in the canopy. It frequently joins mixed-species flocks and flicks its tail while gleaning insects from foliage. Identification can be tricky among similar small flycatchers; look for the crisp gray upperparts, clean whitish underparts, and pale wingbars. Its thin, high-pitched calls are often the best clue to its presence.
Temperament
active and alert
Flight Pattern
short rapid wingbeats
Social Behavior
Usually seen singly or in pairs, often accompanying mixed-species flocks in the canopy. Nests are likely small cups placed on horizontal branches or in forks, with both parents involved in care. Territorial during breeding but otherwise fairly tolerant of nearby conspecifics.
Migratory Pattern
Resident
Song Description
Voice is a series of thin, high-pitched tsee and tsi notes, sometimes given in quick sequences. Calls are sharp and piercing, carrying through the canopy more than the soft song.
Plumage
Neat gray upperparts with clean whitish throat and underparts; two pale wingbars and slightly darker gray crown. Subtle pale supercilium and faint dusky edging on the breast sides may be visible at close range.
Diet
Primarily small arthropods such as flies, beetles, and caterpillars. Gleans prey from leaves and twigs and occasionally sallies short distances to snatch airborne insects. May take tiny berries opportunistically, especially in the dry season when insects are less abundant.
Preferred Environment
Feeds in the mid- to upper canopy of semi-deciduous forest, secondary growth, and along forest edges. Also uses riparian thickets and scattered trees in open country.
