Made available in DSpace on 2022-04-28T19:28:26Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-12-01; Although it is a common species, almost nothing is known concerning the breeding biology of Yellow-margined Flatbill Tolmomyias assimilis. We present the first formal description of the species' nest. It was found in an open area near Manaus, Amazonas state, Brazil, and was, like the nests of other Tolm...
The Chestnut-belted Gnateater is an Amazonian species with a wide distribution, but few studies exist on its reproductive biology and behavior. In this paper we describe the nest and aspects of the behavioral repertoire employed in nest defense. Observations were made on the Dimona farm, in the municipality of Presidente Figueiredo, state of Amazonas. On December 8, 2010, we observed a female Chestnut-belted Gn...
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 Juruá 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 t...
Orange-fronted Plushcrown Metopothrix aurantiaca is a unique, but easily overlooked, small furnariid found in the midstorey and canopy of riverine areas in the Amazon. The species' previously published distribution includes parts of southernmost Colombia, eastern Ecuador, eastern Peru, northern Bolivia and western Brazil. In the easternmost part of its distribution (Brazil), M. aurantiaca occurs in the states o...
From 15 January to 06 February 2016, we conducted an expedition to the Serra da Mocidade, a remote and previously unexplored mountain range in extreme northern Amazonian Brazil. There we encountered three bird species never before documented in Brazilian territory: Grallaria guatimalensis (Grallariidae) was photographed, audio recorded, video recorded and a single specimen collected; Catharus aurantiirostris (T...
Patterns of habitat selection are influenced by local productivity, resource availability, and predation risk. Species have takenmillions of years to hone themacro- andmicrohabitats they occupy, but these may now overlap with contemporary human threats within natural species ranges. Wattled Curassow (Crax globulosa), an endemic galliform species of the western Amazon, is threatened by both hunting and habitat l...
Many Thamnophilidae species have poorly known breeding. Here we describe the nests and eggs of two species, Epinecrophylla ornata from a terra firme forest, and Myrmotherula assimilis from a flooded forest in Brazil. Knowledge on the natural history of these species is important for future conservation strategies. © 2016, Sociedade Brasileira de Ornitologia. All rights reserved.
