You gotta love this bird! On my last trip to Guatemala I rather surprisingly had cracking observations of Pink-headed warbler / Rosenwaldsänger (Ergaticus versicolor). I had seen this gem of the highlands before, but the views at the Sierra de los Cuchumatanes, in the west of the country, blew me away! If you ever happen to get to Todos Santos/Guatemala, be sure to walk the Sendero Ecológico "La Maceta" that ascends from the main road. Pink-headed warbler was - without a doubt - the most common bird there, when I visited this August.
