Santa-Marta-Zaunkönig Troglodytes monticola

Highly endangered wren restricted to grassy and scrubby areas above tree line high up in Colombia’s Santa Marta Mountains. Reaching its habitat involves a multi-day camping expedition, and it cannot be seen in the commonly birded areas lower down the mountains. Rich coloration and heavily barred underparts separate it from House Wren, the only other similar species that could possibly occur in its lofty domain. Song is a descending, tinkling series of notes.
