Black-fronted Nunbird

Fascinating facts about the Black-fronted Nunbird

• At just 26 to 29 cm long, about the length of a school ruler, and weighing only 68 to 98 g, the black-fronted nunbird is a feather-light aerial hunter. Its adult plumage is a deep sooty black that darkens around the bill, with a blue-gray back and a striking red bill that flashes like a tiny lantern in the forest understory. This tiny size lets it dart through tangled bamboo and river-edge trees, catching insects on the wing.
• The nominate subspecies spreads across the Amazon Basin from southeastern Colombia, eastern Ecuador, eastern Peru, and much of Brazil, reaching as far east as the Rio Negro and south to Pará, Alagoas, Mato Grosso do Sul and western São Paulo, while the canescens form lives only in eastern Bolivia. It favors river-margin trees and bamboo, thriving in várzea, igapó, gallery and secondary forests, but avoids terra firme forest. Found from sea level up to 1,000 m (3,300 ft).
• When hunting, the nunbird snatches most of its prey mid-air, yet it will also glean insects, small lizards and amphibians from the ground or foliage up to about 6 m (20 ft) high. It often shadows moving primate troops and army-ant swarms, seizing insects flushed out by those larger foragers, and sometimes joins mixed-species flocks to boost its catch rate. This opportunistic foraging links the bird to the forest's larger food web, turning the movements of mammals and insects into a buffet for a tiny predator.
• Its song is a rapid series of melodious upslurred "clerry" or "curry turra turra" trill, often sung together by several birds in a chorus. The IUCN rates the species as Least Concern, noting its extremely large range and that it is common to abundant across most of that area, though the overall population is believed to be decreasing.
• Breeding runs from April to October, varying across its range, and the bird builds its nest in a hole excavated in a bank or gently sloping ground. Each clutch holds three eggs.
