Although widespread throughout Amazonia, little is known of the breeding biology of Black-bellied Cuckoo Piaya melanogaster and its nest has not been described. We found two nests in French Guiana, both with two nestlings. The open, cup-shaped nests were constructed with twigs, pieces of vine and dead leaves within dense tangles of vines. The nestlings were mainly fed hairy caterpillars and, to a lesser extent, other arthropods. Our observations suggest that the species' breeding biology is similar to that of the closely related and betterknown Squirrel Cuckoo P. cayana.

Until now, the nests of only six of the 12 species of tody-flycatchers of the genus Poecilotriccus have been described. We present general information on the breeding biology of Smoky-fronted Tody-Flycatcher Poecilotriccus fumifrons in French Guiana. Nests we found were similar to those of other Poecilotriccus species for which the nest is known, i.e. closed/ovoid/pensile. © 2016 The Authors; Journal compilation © 2016 British Ornithologists' Club.

The Straight-billed Woodcreeper (Dendroplex picus) is largely insectivorous, but sporadically feeds on small vertebrates. It breeds in cavities, which makes it difficult to follow its breeding cycle. We report here on the use of thin dry branches and strips of bark of considerable length to provide a foundation for the actual nest in a deep woodpecker hole, and the use of dry snake skin to line the nest cavity. We also report the first record of nestlings being fed with eggs.

We present the first details of nesting sites, eggs, and chicks of the Pygmy Nightjar (Nyctipolus hirundinaceus), a small nocturnal bird endemic to northeastern Brazil. We conducted behavioral observations near Curaçá in northern Bahia, and at Potengí, southern Ceará, both located in the heart of the Brazilian Caatinga. We found four 'nests' in Bahia and another five in Ceará. In all cases, a single egg was laid, and only the females took care of the chick during the day. Pygmy Nightjars in both places bred mostly during the rainy season, as do most of the bird species in the region. By gathering breeding data from throughout the species distribution, we observed that although most populations (c. 75%) breed during the rainy season, some populations of the race cearae also seem to breed during the dry season.

The Freckled Nightjar Caprimulgus tristigma and the Blackish Nightjar C. nigrescens are widespread and common within their rupicolous habitat, in the Afrotropics and Neotropics respectively, and may therefore be considered as successful in their adaptation to this habitat, a niche that has not been exploited by any other nightjar species. However, apart from a plumage pattern that matches a rocky substrate, their known life histories provide no common factors to explain this adaptive success. The factors that they do share are common to most other nightjars. While they nest and roost on rocks, their breeding biology is remarkably different. The contrasts and lack of convergence are surprising, and suggest that these two species are not as closely related as their current congeneric status implies. This is supported by recent molecular studies that place the African and South American Caprimulgus species in different well-supported clades. © NISC (Pty) Ltd.
