Vireolanius leucotis
The Slaty-capped Shrike-Vireo (Vireolanius leucotis) is a striking, medium-sized passerine, often described as an arboreal gem of the Neotropics. Measuring approximately 13-14 cm (5.1-5.5 inches) in length and weighing around 15-20 grams, it features a distinctive slaty-grey crown, a broad white supercilium, and a prominent black mask extending from the lore through the eye. Its back and wings are a vibrant olive-green, contrasting sharply with its bright yellow underparts, which may have a g...
Primarily inhabits humid evergreen forests, including montane evergreen forests, cloud forests, and mature secondary growth. Typically found at elevations ranging from 500 to 2,000 meters.
Feeds primarily on insects and other arthropods, such as caterpillars, beetles, and ants, gleaned from foliage and branches. Occasionally consumes small fruits.
Slaty-capped Shrike-Vireos are highly arboreal, spending most of their time in the mid to upper canopy, often moving actively through the foliage. They are frequently observed as participants in mixed-species foraging flocks, acting as a 'nuclear species' that other birds follow. Their primary fo...
The Slaty-capped Shrike-Vireo boasts an extensive, continuous distribution across Central and South America, primarily as a resident species. Its northernmost range extends into southern Mexico (Veracruz, Oaxaca, Chiapas), continuing southward through Guatemala, Belize, Honduras, Nicaragua, Costa...
