Amazonian vultures dip for sashimi: a novel foraging behaviour for Cathartidae
Springer Science and Business Media LLC - Tập 30 - Trang 281-283 - 2022
Fábio Olmos, Ivan Sazima
New World vultures (Cathartidae) are well-known for feeding on dead aquatic animals, especially fish, and two cathartid species wade into water or plunge from riverbank to take live fish. Herein, we describe a foraging behaviour of two species of the genus Cathartes, which dip into water while airborne to pick floating fish pieces resulted from human or dolphin fishing activity. The vultures spot ...... hiện toàn bộ

Influence of environmental enrichment on the behavioral variables of caged Hyacinth Macaws (Anodorhynchus hyacinthinus)
Springer Science and Business Media LLC - Tập 28 - Trang 125-132 - 2020
Cristiane Tibério Checon, Derek A. Rosenfield, Pedro Nacib Jorge-Neto, Cristiane Schilbach Pizzutto
The Hyacinth Macaw (Anodorhynchus hyacinthinus) is a species considered vulnerable by the IUCN Red List, and many individuals are found in captivity in Brazil. In captive environments, due to the lack of stimuli, these animals demonstrate abnormal behaviors due to a high degree of inactivity. Among the strategies to minimize this problem, increase the natural behavior, and improve the well-being a...... hiện toàn bộ
Current knowledge of the poorly studied diet of the comb-crested jacana (Irediparra gallinacea)
Springer Science and Business Media LLC - - 2024
Matthew Mo, Elouise Mo
Dietary studies inform species conservation management. The comb-crested jacana (Irediparra gallinacea) is unique amongst avian diversity within its distribution and is listed as threatened under New South Wales legislation in Australia but has been the subject of few biological studies. This short communication summarises present information on dietary items of this species. Plant dietary items a...... hiện toàn bộ
First records of Macgillivray’s prion Pachyptila macgillivrayi in Uruguayan and Argentine waters
Springer Science and Business Media LLC - Tập 31 - Trang 323-325 - 2023
Joaquín Muñoz, Christian Savigny, Diego Castelli, Sebastián Jiménez
The MacGillivray’s prion Pachyptila macgillivrayi is a small petrel that breeds at Saint-Paul Island, Indian Ocean, in addition to a population recently discovered at Gough Island, central-southern South Atlantic Ocean. The non-breeding distribution of the Gough Island population is poorly known. Tracking data revealed a westward dispersion to oceanic waters off southeastern South America. Here, w...... hiện toàn bộ

Territory size, population density, and natural history of Cabanis’s Ground Sparrow, an endemic species found in urban areas
Springer Science and Business Media LLC - Tập 29 - Trang 227-239 - 2021
Roselvy Juárez, María de la Paz Angulo Irola, Ernesto M. Carman, Luis Sandoval
Worldwide urban expansion threatens biodiversity inhabiting the original natural environments now being transformed, especially range-restricted species. Here, we provide estimates of population density, population size, and territory size of Cabanis’s Ground Sparrow Melozone cabanisi, a Costa Rican endemic. Additionally, we provide information about its life history. We measured abundance and est...... hiện toàn bộ
Bird dependence on wetlands determines functional responses to flood pulse in the Brazilian Pantanal
Springer Science and Business Media LLC - Tập 30 - Trang 190-203 - 2022
Angélica Vilas Boas Frota, Breno Dias Vitorino, Sara Miranda Almeida, Josué Ribeiro da Silva Nunes, Carolina Joana da Silva
Hydrological regimes in floodplains are essential to support biodiversity that depend on wetlands, and understanding how these organisms are associated to this ecosystem could be useful, as they can act as important agents for the maintenance of diversity and natural processes. We aimed to assess the bird functional responses to the Pantanal flood pulse, considering the hydrological periods and th...... hiện toàn bộ
A new feeding association between black-goggled tanagers (Tachyphoninae) and black lion tamarins (Primates, Callitrichinae)
Springer Science and Business Media LLC - Tập 30 - Trang 216-220 - 2022
Felipe Bufalo, Rodrigo Gonçalves Amaral, Olivier Kaisin, Laurence Culot
Insectivorous-frugivorous birds have been described to benefit from multiple forms of interspecific feeding associations. Here we present quantitative data on a new feeding association between the black-goggled tanager (Trichothraupis melanops) and an endangered frugivorous-faunivorous neotropical primate, the black lion tamarin (Leontopithecus chrysopygus), at an Atlantic Forest remnant in São Pa...... hiện toàn bộ
