Genetic structure reveals management units for the yellow cardinal (Gubernatrix cristata), endangered by habitat loss and illegal trapping [PDF]
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.

Cooperative breeding and demography of Yellow Cardinal Gubernatrix cristata in Brazil
Revista Brasileira de Ornitologia, 2017 We studied demography, territoriality and social system of the Brazilian population of Yellow Cardinal, Gubernatrix cristata . The study was conducted in the municipality of Barra do Quarai, western Rio Grande do Sul, Brazil, during two breeding seasons (October to February, 2013–2015).

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.

Evidence for the evolution of male and female cardinals’ plumage colouration being affected by both natural and sexual selection [PDF]
BMC Ecology and EvolutionThe evolution of sexually selected traits, such as colouration, has been the object of considerable research. Among birds, plumage colouration is highly variable and includes some of the most exuberant signals.
