Amazonian vultures dip for sashimi: a novel foraging behaviour for CathartidaeSpringer 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
On misinterpretations of the General Lineage Species Concept: a response to Aleixo (2023)Springer Science and Business Media LLC - Tập 31 - Trang 231-235 - 2023
Rafael Dantas Lima
In a recent commentary in this journal, I argued that the General Lineage Species Concept has been misunderstood in Brazilian ornithology and that it has sometimes been misapplied in the influential checklist of the birds of Brazil by the Brazilian Ornithological Records Committee. One of the committee members has recently published an invited response to my commentary. Unfortunately, many of my a...... 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

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
Avian functional diversity across the neotropics: current knowledge and perspectivesSpringer Science and Business Media LLC - - Trang 1-9 - 2023
Marisela Martínez-Ruiz, Rafael Rueda-Hernández
The value of birds as indicators of environmental change is of greater relevance given the current rapid habitat loss and transformation rates. This is no more important than in the megadiverse Neotropical realm, which is experiencing accelerated biodiversity loss. Evaluation of the ecological role or functional diversity of avian communities is rapidly replacing traditional indices of species div...... hiện toàn bộ
Environmental factors shaping habitat suitability of Gyps vultures: climate change impact modelling for conservation in IndiaSpringer Science and Business Media LLC - Tập 31 - Trang 119-140 - 2023
Radhika Jha, Kaushalendra Kumar Jha
Out of eight Gyps species in the world, three residents (G. bengalensis, G. indicus, G. tenuirostris) and two migratory (G. fulvus, G. himalayensis) inhabit Indian forests and other landscapes. While Himalayan and Eurasian Gyps are near threatened and least concerned species, respectively, the resident Gyps are critically endangered. They are facing modification in habitats caused by anthropogenic...... hiện toàn bộ

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
