Feeding habits

Despite its long curved beak, it feeds like the other birds of the same species, climbing trunks and branches in search of insects and other small invertebrates. It looks for its prey in crevices, under the bark of trees or in plants such as bromeliads. It lives alone or in pairs, frequently following mixed-species flocks.


This species has a large range, with an estimated global extent of occurrence of 3,500,000 km². The global population size has not been quantified, but the species is not believed to approach the thresholds for the population size criterion of the IUCN Red List (i.e., less than 10,000 mature individuals in conjunction with appropriate decline rates and subpopulation qualifiers), even though the species is described as ‘uncommon’ in at least parts of its range (Stotz et al. 1996). Global population trends have not been quantified, but 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.
