Breeding Ecology of Southern Caracaras (Caracara plancus) in Southern Continental Patagonia, Santa Cruz Province, Argentina

Journal of Raptor Research, 2021
We searched for nests and studied aspects of the breeding biology of Southern Caracaras (Caracara plancus) in the Patagonian grasslands biome of southern Santa Cruz province, Patagonia, Argentina, at the southern limit of the species' continental distribution. In this open, mostly flat landscape where potential nest substrates are rare and isolated yet

Presence of micronuclei and nuclear abnormalities in Caracara (Polyborus) plancus living in an airport area in southern Brazil

Journal of Toxicology and Environmental Health, Part A
The aviation sector is believed to be responsible for considerable environmental damage attributed to emission of a large number and amount of pollutants. Airports are often surrounded by forest fragments and humid areas that attract birds of prey and hence may potentially serve as useful bioindicators.
