Botfly parasitism effects on nestling growth and mortality of Red-crested Cardinals
(Wilson Ornithological Society, 2011-03)
We collected observational data in three consecutive breeding seasons to study interactions between the botfly Philornis seguyi and Red-crested Cardinals (Paroaria coronata) in a temperate zone near the southern limit of ...
Male Red-crested Cardinal plumage coloration is associated with parental abilities and breeding performance
(Nature Publishing Group, 2019-12)
Avian plumage coloration deriving from carotenoid-based pigments is among the most honest signals of individual quality. It has been argued that females may differentially allocate resources based on mate attractiveness ...
Hybridization between yellow-billed cardinal paroaria capitata and red-crested cardinal P. Coronata in southern Argentina
(Sociedade Brasileira de Ornitologia, 2019-06)
The 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 ...
Red-crested cardinal defences against shiny cowbird parasitism
(Brill Academic Publishers, 2012-04)
Avian brood parasites reduce the reproductive success of the host, which favours the evolution of antiparasitic defences, such as aggression towards parasites or rejection of their eggs. The red-crested cardinal, Paroaria ...
Microhabitat nest cover effect on nest survival of the Red-Crested Cardinal
(Wilson Ornithological Society, 2012-09)
Predation is the primary cause of nest failure of birds and factors affecting predation risk have shaped the evolution of avian life histories. We evaluated the influence of microhabitat vegetation cover on Red-crested ...
Quantifying the relative importance of direct and indirect effects influencing bird nestling growth
(John Wiley & Sons Inc., 2021-04)
Nestling growth parameters are integral components of avian life-history strategies as they are crucial determinants of individual survival. Although many factors impact on nestling growth, the relative contribution of ...
Supervivencia de nidos del Cardenal Común (Paroaria coronata) en un hábitat modificado en ArgentinaNest survival of the Red-crested Cardinal (Paroaria coronata) in a modified habitat in Argentina
(Neotropical Ornithological Society, 2012-12)
La modificación de los sitios de nidificación causada por la actividad humana puede tener un efecto negativo sobre el éxito reproductivo de las aves. En las últimas décadas, una población de Cardenal Común (Paroaria coronata) ...
Red-crested Cardinals use color and width as cues to reject Shiny Cowbird eggs
(American Ornithologists' Union, 2016-04)
Como parte del proceso coevolutivo entre los parásitos de cría y sus hospedadores, estos últimos han desarrollado diferentes estrategias para discriminar y rechazar los huevos parásitos. Este proceso de reconocimiento y ...
