Hematological parameters and stress index in Rufous-collared Sparrows dwelling in urban environments
(American Ornithologist Society, 2002)
A number of wild bird species have fortuitously incorporated themselves into urban life. One of these, the Rufous-collared Sparrow (Zonotrichia capensis), dwells with seemingly similar success in urban and rural areas. ...
Stability and change through time in the dialects of a Neotropical songbird, the Rufous-collared Sparrow
(Csiro Publishing, 2016-12)
Behavioural characters that are learned can show temporal variation due to changes in a population across generations that are not due to changes in the same individual. The song of the Rufous-collared Sparrow, Zonotrichia ...
Intraspecific variation in exploratory behavior and elevational affinity in a widely distributed songbird
(SPRINGER, 2018)
Populations of the same species can vary substantially in their behavioral and morphometric traits when they are subject to different environmental pressures, which may lead to the development of different adaptive strategies. ...
Avian haemosporidian infections in rufous-collared sparrows in an Andean dry forest: diversity and factors related to prevalence and parasitaemia
(Cambridge University PressParasitology, 2019)
A blurring of life-history lines: Immune function, molt and reproduction in a highly stable environment
(Elsevier, 2015)
Rufous-collared sparrows (Zonotrichia capensis peruviensis) from valleys in the Atacama Desert of Chile,
live in an extremely stable environment, and exhibit overlap in molt and reproduction, with
valley-specific differences ...
Seasonal changes in diet, digestive morphology and digestive efficiency in the Rufous-collared Sparrow (Zonotrichia capensis) in central Chile
(University of California Press, 1996)
Geographic variation in the response to thermal acclimation in Rufous-collared Sparrows: are physiological flexibility and environmental heterogeneity correlated?
(2008)
It has been proposed that habitats with low productivity, and hence low resource availability, may favour individuals with lower rates of resource use and energy expenditure. In birds, some studies have shown that basal ...
