Paltry Tyrannulet Zimmerius vilissimus

Paltry Tyrannulet is a common and familiar small flycatcher of Central America and northwestern South America. It feeds heavily on mistletoes (with fruits and insects rounding out their diet), and is found in habitats where mistletoes are common, including forests, forest edges, orchards, and pastures interspersed with trees. Paltry Tyrannulet occurs at all elevations in Central America, and at mid-elevation in eastern Colombia and northern Venezuela. It is readily identified by its distinctive wing markings: olive-green wing feathers are outlined in yellow (thicker on the leading edge of each feather), but do not form wing bars. It may be easily overlooked, but can be located by its frequently uttered, plaintive pyeer call. Paltry Tyrannulet is in need of taxonomic revision, and may be comprised by two or more valid species.
