The collared whitestart (Myioborus torquatus), also known as the collared redstart, is a species of bird in the family Parulidae, the New World warblers. It is found in Costa Rica and Panama. The collared whitestart was formally described in 1865 with the binomial Setophaga torquata. It is monotypic.
The collared whitestart is about 12 to 13.5 cm (4.7 to 5.3 in) long and weighs about 10 to 11 g (0.35 to 0.39 oz). The sexes have the same plumage. Adults have rufous central crown with a black border beneath it that extends to the nape; the rest of their head including the throat is yellow. Their upperparts and wings are slate gray. Their tail is blackish with much white on the outer two pairs of feathers. Their underparts are yellow with a slate gray band across the upper breast. They have a mouse-brown iris, a black bill, and dusky brown or black legs and feet. Juveniles have a slate gray head with no rufous or yellow. Their upperparts are dark slate gray with a brown wash. Their throat and breast are slate gray and their belly dull yellow.

GBIF citizen-science records
It is estimated from how often the Collared Redstart is recorded against all the birds logged in Irazú Volcano National Park (82 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
