The Black-collared Hawk Busarellus nigricollis is widespread from southern Mexico throughout Central America and east of the Andes in South America. Although rather common in most of its distribution range, little is known about its breeding biology as nests are often built in inaccessible areas. The discovery in 2013 of four nests of this hawk in the coastal region of French Guiana, where it is found near brackish or fresh water in semi-open to open country, allowed us to increase our knowledge of its breeding behavior. The population is estimated at c. 200 pairs. Aerial displays of a breeding pair cover a large area around the nest tree. The nest is a large structure of sticks with a shallow cup lined with finer branches and a layer of twigs with leaves. It is mostly built at a height between 15 and 35 m, in the crown of an isolated tree or in a tree crown emerging above the surrounding vegetation. A single egg per nest is laid in French Guiana. The fledgling period for one nest was 55 days. Both male and female incubate and feed the nestling, although the female’s share in both activities is more important. During the entire nesting period male and female add fresh twigs with leaves and to a lesser extent, fine dead branches to the nest. © 2016, Sociedade Brasileira de Ornitologia.

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.

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.

Setopagis maculosa (Todd, 1920) (Aves: Caprimulgidae) was described based on a single male specimen collected by Samuel Milton Klages in French Guiana, northeastern South America. Since then, no new specimens have been collected nor have any reliable records been made, and the validity of the species has been questioned. A detailed analysis of the holotype reveals that it has unique and distinctive morphological traits that support the validity and taxonomic status of the species, which is provisionally placed in Setopagis. We present new information on the type locality at the time of its collection, which may shed some light on the habitat preferences of the species, and we provide details on its plumage that have been largely overlooked and that will be important for future field identification.

We discuss the choice of habitats for roosting and breeding by the Pygmy Nightjar (Nyctipolus hirundinaceus), a Brazilian endemic from the eastern part of the country. We observed that the choice of nesting and roosting sites of this nightjar is closely connected to open gravelly and stony areas (lajeiros) in the Caatinga and to rocky outcrops (pedras) in the Atlantic Forest, which allows us to conclude that the Pygmy Nightjar is a rupicolous nightjar, preferring rocky substrates for roosting and breeding.


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.

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.

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.

We describe the opportunistic adaptation to man-induced changes in the habitats of six neotropical Caprimulgidae. Habitats created by those changes, and similar to their original and usual ones, are readily occupied by these nightjars. The occasional invasion of urban environments (urbanization) is the most recent and most remarkable behavioural adaptation.
