Hybridization Between Yellow-Billed Cardinal Paroaria capitata and Red-Crested Cardinal P. Coronata in Southern Argentina [PDF]

Revista Brasileira De Ornitologia, 2019
AbstractThe genus Paroaria is a group of conspicuous songbirds widely distributed in South America that has been studied recently to delimit its species and establish their phylogenetic relationships. Although hybridization has been reported between the most phylogenetically related species of the genus, we here present a case of hybridization between ...

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 ...

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.

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 ...

Genetic Structure Reveals Management Units for the Yellow Cardinal (Gubernatrix cristata), Endangered by Habitat Loss and Illegal Trapping

Conservation Genetics, 2017
The yellow cardinal, Gubernatrix cristata, is an endangered passerine from southern South America. Populations are declining due to the loss of their natural habitat, which has caused a fragmented distribution, and the continuous extraction of individuals from the wild, mainly males, to sell them as cage birds.

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 ...

The Lack of Males Due to Illegal Trapping Is Causing Polygyny in the Globally Endangered Yellow Cardinal Gubernatrix cristata [PDF]

Revista Brasileira De Ornitologia, 2019
AbstractWe present breeding data from the southernmost populations of the globally “Endangered” Yellow CardinalGubernatrix cristatain Argentina, confirming the presence of current breeding populations in the region. We monitored a family group in a nesting territory composed of one male and three females throughout the breeding season 2017–2018.
