Genetic assignment and monitoring of yellow cardinals

Journal of Wildlife Management, 2019
ABSTRACTThe yellow cardinal (Gubernatrix cristata) is a passerine bird endemic to southern South America. At present, the species is threatened with extinction, in part because of the capture of wild birds to supply the illegal caged‐bird market. Previous genetic evidence supports the existence of 3 management units for the species in Argentina, where ...

Blood parasites of passerines in the Brazilian Pampas and their implications for a potential population supplementation program for the endangered Yellow Cardinal (Gubernatrix cristata)

Parasitology Research, 2022
Espinilho savanna ("seasonal steppe savanna") is a unique vegetation formation of the Pampas biome that is found near the tri-border of Brazil, Uruguay, and Argentina. The Yellow Cardinal (Gubernatrix cristata) is a flagship species of this ecosystem, but it is classified as "critically endangered" in Brazil due to habitat loss and poaching for the ...

Family group structure of the endangered Yellow Cardinal ( Gubernatrix cristata )

Avian Biology Research, 2023
The monogamous mating system, where a male and a female constitute the reproductive unit and share the parental care, predominates among bird reproductive strategies. However, there are also other mating systems with diverse parental care roles which may have implications for population breeding success and be relevant for their management and ...

Seed preferences suggest a high vulnerability of the Yellow Cardinal (Gubernatrix cristata) to habitat degradation in Argentina

Emu - Austral Ornithology, 2022
The Yellow Cardinal is a globally endangered species endemic of southern South America. Knowledge of its general biology has increased in recent years, but its feeding ecology is less well-known. Assessing the feeding ecology of endangered species imposes ethical dilemmas, and we therefore took advantage of Yellow Cardinals rescued by rangers from ...

Yellow Cardinal (Gubernatrix cristata) males respond more strongly to local than to foreign dialects

Ibis, 2023
Bird song is a culturally transmitted behavioural trait strongly tied to territory defence and mate attraction in oscine passerines. Divergent song variations can appear in different populations of the same species as a consequence of multiple factors generating geographically distinct songs also termed dialects. Most studies show that males react more

A citizen science survey discloses the current distribution of the endangered Yellow CardinalGubernatrix cristatain Argentina

Bird Conservation International, 2020
SummaryThe Yellow CardinalGubernatrix cristatais a globally endangered passerine from the southern cone of South America. Because of its conspicuous plumage and very attractive song, it suffers considerably from illegal pet trade. The largest remaining populations are found in Argentina, but no coordinated efforts have been made thus far to understand ...

Genetic diversity in captive Yellow Cardinals (Gubernatrix cristata) from Southern Brazil: implications for the management and conservation of an endangered species

Journal of Ornithology, 2021
Yellow Cardinal is an Endangered Species. Its populations are in constant decline due to habitat reduction and loss and illegal capture. There are approximately 50 free-living animals in the south of Brazil (state of Rio Grande do Sul), but estimates indicate more than 1000 in captivity.

Occurrence patterns of the endangered Yellow Cardinal Gubernatrix cristata in north-east Argentina: only in savannahs and at sites away from roads

Bird Conservation International, 2022
Summary The endangered Yellow Cardinal Gubernatrix cristata is under pressure from habitat loss and from capturing for the cage bird trade. In north-east Argentina it is known to be associated with the Espinal ecoregion, but no information was available on habitat selection within this ecoregion.

Metabolizable energy in Chinese Tallow fruit for Yellow-rumped Warblers, Northern Cardinals, and American Robins

The Wilson Journal of Ornithology, 2008
Abstract The invasive exotic Chinese tallow tree (Triadica sebifera) produces an abundant fruit crop, which is primarily bird-dispersed. The fruit pulp of tallow is lipid-rich, high in saturated fatty acids, and consumed by many bird species. Long-chained fatty acids can be difficult for many birds to digest and we investigated the ability of tallow ...
