This bird, which I have tentatively IDed as a Tennessee Warbler, was photographed in the central highlands of Costa Rica. I am no expert on bird IDs; in fact I am not much of a birder at all. I just like taking photos of them. This bird also shows the difficulty in IDing birds when they are not in their “usual” habitats. Certainly Tennessee Warblers do winter in Central America, but I think many, if not most, people from the USA think of warblers as North American birds. Anyway, I keep wanting to ID this bird as type of tyrannulet, but nothing pops up in Merlin/eBird. Any thoughts?
