Abstract
Chestnut-capped Puffbird Bucco macrodactylus, like other members of the Bucconidae family, nest in arboreal termitaria. Here we described a nest of the species, found in the floodplain of the Jurua River in December 2014. It was built inside an arboreal termite mound, 2.45 m above the ground. We determined the type and frequency of prey consumed by chicks over six days: during this time adults brought food to the nest 147 times. Prey included both vertebrates and invertebrates, though the most frequent were insects of the Order Orthoptera. Fledging may have been directly stimulated by a predation attempt made by a marsupial.
Highlights
Chestnut-capped Puffbird (Bucco macrodactylus) is the smallest of the Amazonian Bucconidae, with no sexual dimorphism
The diet of the species consists of small vertebrates and large arthropods, with adults foraging alone (Rasmussen et al 2016a)
Breeding is well known for only a few bucconids, while for most puffbird species there are few, if any, records of nesting and parental care
Summary
Chestnut-capped Puffbird (Bucco macrodactylus) is the smallest of the Amazonian Bucconidae, with no sexual dimorphism. Both parents care for the chicks, sometimes with the assistance of an additional adult (Sick 1997). Breeding is well known for only a few bucconids, while for most puffbird species there are few, if any, records of nesting and parental care.
