During two breeding seasons October to February — , we monitored nests and described the main breeding traits. The breeding season started from the first week of October, with a peak of active nests in mid-November and lasted until mid-February. We found 32 nests, of which 30 were monitored. All nests were built on Prosopis trees, on average at 2.
Parasitism in nestlings by botfly larvae Philornis sp. We found a longer breeding season, occurrence of second broods, and higher rates but fewer nest losses due to brood parasitism in comparison to the Argentinian population.
We highlight the importance of natural history studies for the conservation of different populations of the same species. Download to read the full article text. Alvares C.

The yellow cardinal Gubernatrix cristata is a species of bird in the family Thraupidae. It is the only member of its genus , Gubernatrix. It is found in Argentina , Brazil , Paraguay , and Uruguay. Its natural habitats are dry savanna , temperate shrubland , subtropical or tropical moist shrubland, and temperate grassland. It is threatened by habitat loss and from pet trade trappers. As such, the Yellow Cardinal is characterized as endangered due to the constant entrapment. It was found that there was some variation with the Common Diuca Finch [ clarification needed ] .
