VARIACION DEL HEMATOCRITO DURANTE EL PERIODOREPRODUCTOR EN EL RABILARGO CYANOPICA CYANUS
Azure-winged Magpie (Cyanopica cyanus) Science Article 3 abstract Changes in the haematocrit in Azure-winged Magpies Cyanopica cyanus during the reproductiveperiod. Previous studies have suggested that the haematocrit could be related to a number of factors within the birds’ biological cycle. In this study, the variation found in the haematocrit of Azure-winged Magpies Cyanopica cyanus during […]
Testosterone and helping behavior in the azure-winged magpie(Cyanopica cyanus): natural covariation and an experimental test
Azure-winged Magpie (Cyanopica cyanus) Science Article 2 abstract In this study, we investigated patterns of natural covariation between testosterone and reproductive status in a cooperatively breeding bird species, the azurewinged magpie (Cyanopica cyanus). To assess the relationship between testosterone and breeding behavior,we also manipulated testosterone (T) levels early in the season (before breeding started) using […]
