Verhalten

The long-billed crombec's nest is a large, hanging bag of grasses, spider webs, and plant fibres, which is attached to the lower limbs of a tree, often an Acacia. The one to three white eggs are incubated for two weeks to hatching, and the chicks are fed by both parents for another two weeks to fledging. This territorial species is monogamous, pairing for life.<p>This bird is usually seen alone, in pairs, or in family groups as it forages methodically from the bottom to the top of bushes and trees for insects and grass seeds. It will join mixed-species feeding flocks.<p>It moves between trees with a bouncy flight.

Schutzstatus

This common species has a large range, with an estimated extent of 4,500,000 km². The population size is believed to be large, and the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e. declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as least concern.
