The Brown Nunlet (N. brunnea) is one of six species of small puffbirds in the genus Nonnula. Here, we describe a nest of Brown Nunlet from Amazonian Ecuador. The nests' architecture diverges from that of other bucconids, built neither in a subterranean burrow nor in a termitarium, but rather is a flattened, dome-shaped structure composed of leaf litter above a shallow depression. Structural integrity of the leafy dome is created with carefully placed sticks and the inner chamber is entered through a short tunnel. We also provide observations that clarify uncertainties in nest placement of White-chested Puffbird (Malacoptila fusca) and observations on the breeding of other Bucconidae in Amazonian Ecuador.

Life-history strategies of Neotropical birds differ markedly from their Nearctic counterparts, yet the lack of detailed information on most Neotropical species hinders meaningful comparisons. We performed a gap analysis with several basic life-history traits of New World flycatchers of the subfamily Fluvicolinae. We found breeding data - mostly on clutch sizes and linear egg measurements - in 303 publications spanning the years 1838 to 2012. Data from the USA and Argentina were more abundant, with the number of publications per country being significantly and positively related to human development index (HDI) and Fluvicolinae breeding species richness. The amount of available clutch size information for each species was positively related to species' range size and relative abundance. More research is needed concerning narrowly distributed and uncommon species. Additional efforts to gather data on all Neotropical species are, however, crucial for future advancements. © 2013 ABECO.

Thripadectes treehunters are among the most poorly known cavity-nesting furnariids. In this paper we review the existing information on their nests, present new field observations from ecuador, and add unpublished museum data. We describe for the first time the nests of two species, T. flammulatus and T. holostictus. Nests of Thripadectes are all shallow cups of vegetative material, lacking any lining of animal origin such as feathers or hair. Most species have consistent preferences for particular plant materials. Thripadectes rufobrunneus, T. virgaticeps, and T. holostictus use mainly rootlets, T. melanorhynchus uses stems of compound leaves exclusively, and T. flammulatus incorporates plant materials derived from grass, bamboo, and treeferns. Larger samples of nests from across these species' ranges are needed to determine the generality of this pattern and whether the availability of material plays a role. Several features of Thripadectes nest architecture are shared by putative sister genera Automolus, Hylocryptus, and Hyloctistes. © The Cooper Ornithological Society 2010. Source

The Ash-breasted Tit-Tyrant (Anairetes alpinus) is a range-restricted flycatcher (Tyrannidae) inhabiting the high Andes of Peru, Bolivia, and Argentina. I provide the first description of nest architecture for this species based on a nest encountered in southern Peru. The nest was a deep, compact cup of moss, thickly but loosely lined with feathers and built 1.4 m above the ground in a hanging epiphyte clump. It was similar in architecture and means of support to the nests of other Anairetes, all of which also share an internal lining of feathers. Source

The Pearled Treerunner (Margarornis squamiger) is a small ovenbird (Furnariidae) inhabiting the upper strata of Neotropical montane forests. Little is known of its breeding habits despite its wide distribution and abundance within appropriate habitat. The genus Margarornis is considered closely related to Premnoplex barbtails, but details of nest architecture supporting this relationship are unavailable. Here we provide the first detailed description of nest architecture for the Pearled Treerunner from a nest encountered in northwest Ecuador. The nest was a tightly woven ball of moss and rootlets, similar in shape to that of the Spotted Barbtail (Premnoplex brunnescens) and presumably built in a similar manner. Nest architecture and nestling behavior support a close relationship between Margarornis and Premnoplex. Source
