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 Tolmomyias species whose nests have been described, a closed structure, suspended from a branch, with an entrance tunnel.
Although birds are a well-studied group, the breeding biology of many species is still poorly known, especially in the Neotropical region. This lack of knowledge implies the absence of subsidies for conservation, lack of more reliable data for phylogenetic reconstruction, and for studying the effects of environmental change on these species. In view of this scenario we collected information on the reproduction of 15 bird species in 16 Brazilian locations from February 2003 to December 2021. This article presents new data on the nests, eggs, juveniles/nestlings and/or breeding behavior of Veniliornis spilogaster (Picidae), Philydor atricapillus (Furnariidae), Myiobius barbatus (Onychorhynchidae), Tityra semifasciata (Tityridae), Phylloscartes paulista (Rhynchocyclidae), Phylloscartes oustaleti (Rhynchocyclidae), Elaenia obscura sordida (Tyrannidae), Tyrannus albogularis (Tyrannidae), Cnemotriccus fuscatus (Tyrannidae), Icterus pyrrhopterus (Icteridae), Nemosia pileata caerulea (Thraupidae), Trichothraupis melanops (Thraupidae), Thlypopsis sordida (Thraupidae), Cyanophonia cyanocephala (Fringillidae) and Chlorophonia cyanea roraimae (Fringillidae). We include new data on parental care for six species, descriptions of nests for eight species, and new information on nest building behavior for five species. This data is of special interest for the management of these species and their habitats and for the reconstruction of their phylogenetic relationships.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
