Résumé :
|
The Nacunda Nighthawk (Chordeiles nacunda) is an aerial insectivore and migratory species widely distributed throughout open areas of South America. Here, we report the stomach contents of one female collected in May 2023 in south-central Brazilian Amazon, along the Aripuanã River. The stomach contents of the bird consisted of 136 insects, belonging to 11 orders and 19 families; four orders and nine families are new to the diet of this species. Most of the items found are insects common in open vegetation areas or pastures. This suggests that the bird was taking advantage of the habitat transformations occurring in south-central Amazonia, where native evergreen forests are being replaced by pastures for cattle ranching. The native vegetation at our study area was replaced by pasture sometime between 2018 and 2019.
