The Slate-throated Whitestart is part of the Myioborus genus that includes also the Golden-fronted and Collared Whitestart or Redstart, as are called sometimes. It is a varied genus of warblers that are present in all of the American continent, in different species. In Costa Rica, the Slate-throated is also found along with the Collared species, although here they are called Redstarts instead. They forage very actively on the ground or low in the bushes, flashing their tail to frighten insects that are then caught in the air. Their upper parts and throat are dark grey, while their underparts are yellow in the south, and red on the northernmost part of their range. It also shows a dark red crown that’s difficult to see unless in good light.
