The Black-chinned Mountain-Tanager (Anisognathus notabilis) is one of five species of Mountain-Tanager that have been registered in Santa Lucía. It is somewhat erratic, which means, it's difficult to predict when or where they will appear. They join mixed flocks (like the abundant Blue-winged Mountain-Tanager), but seems to be only present in pairs (unlike the abundant Blue-winged Mountain-Tanager which appears in groups). Most of our observations are around near forest edges at the elevation of the lodge and even in trees in the pastures (e.g. near Eduardos house).
