The collared whitestart, also known as the collared redstart, is a tropical New World warbler endemic to the mountains of Costa Rica and western-central Panama.
Region
Central American highlands
Typical Environment
Occurs in the montane cloud forests and elfin forests of Costa Rica and western to central Panama. Prefers mossy oak and evergreen forests with dense understory, forest edges, and second growth near streams and ravines. Frequently forages along shaded trails and clearings where insects are more easily flushed. It is largely tied to intact mid- to high-elevation forest but can use semi-open habitats adjacent to mature woodland.
Altitude Range
1500–3300 m
Climate Zone
Highland
Ease of Keeping
Beginner friendly: 1/5
Also called the collared redstart, this lively warbler is famous for flashing its white tail edges and fanning its tail to flush insects from foliage. It is often remarkably confiding along mountain trails and may follow hikers, using their movement to stir up prey. Pairs maintain territories year-round in cloud-forest habitats. The species is a hallmark bird of Costa Rica’s and western Panama’s highlands.
Temperament
social and active
Flight Pattern
short rapid wingbeats with frequent flitting and sallying
Social Behavior
Usually found in pairs that defend territories year-round; often joins mixed-species flocks while foraging. Nests are well-concealed cup structures placed low on banks, in moss, or among roots near streams. Both parents participate in feeding the young and remain attentive around the nest. Displays frequent tail-fanning and wing-flicking while moving through the understory.
Migratory Pattern
Resident
Song Description
Song is a sweet, thin series of high trills and tinkling notes delivered from low to mid canopy. Calls include sharp chips and high-pitched tsee notes, often given while actively foraging and tail-fanning.
Plumage
Bright yellow face and underparts with a contrasting dark hood and a distinct black breast band forming a 'collar'; back olive to grayish with dark wings. Tail is dark with bold white outer tail feathers often fanned during foraging. Crown shows a rich rufous to chestnut patch that stands out against the dark hood.
Diet
Feeds primarily on small arthropods, including insects and spiders. Captures prey by gleaning from leaves and moss, making short sallies to snatch flushed insects. Tail-fanning and wing-flicking help disturb hidden prey. Occasionally hawks briefly in midair when insects take flight.
Preferred Environment
Forages in the understory and midstory of mossy cloud forests, along shaded trails, forest edges, and near streams and ravines. Often works through tangles, ferny banks, and epiphyte-laden branches where insect density is high.
