Laniisoma elegans
The Brazilian Laniisoma (Laniisoma elegans) is a striking passerine from the Tityridae family, known for its strong sexual dimorphism and disjunct distribution across humid South American forests. Measuring approximately 17-17.5 cm (6.7-6.9 inches) in length, the male is resplendent with bright yellow underparts, olive-green upperparts, a black mask around the eyes, and a conspicuous, often concealed, orange-red crest atop its black crown. Females, in contrast, display duller olive-green uppe...
Found primarily in humid lowland and montane evergreen forests, including Atlantic Forest remnants and Andean cloud forests, typically from 200m up to 2100m elevation. It prefers the canopy and subcanopy layers of mature forest.
Feeds primarily on arthropods such as insects and spiders, which it catches by sally-gleaning from foliage. It also consumes small fruits, plucking them from branches while perched or in short flights.
The Brazilian Laniisoma is typically an inconspicuous bird, often observed alone or in pairs, occasionally joining mixed-species foraging flocks, particularly in the canopy or subcanopy. It exhibits a somewhat sluggish foraging style, perching upright for extended periods before making short sall...
The Brazilian Laniisoma has a highly disjunct distribution across South America, comprising three main populations. The nominate subspecies, *L. e. elegans*, is found in southeastern Brazil (from Alagoas south to Rio Grande do Sul), eastern Paraguay, and northeastern Argentina (Misiones), primari...
