The raptor Chimango Caracara (Milvago chimango) (Aves: Falconiformes) - A new host for Trichomonas gallinae (protozoa: Trichomonadidae) [PDF]
International Journal for Parasitology: Parasites and Wildlife, 2019 This work describes a specimen of Chimango Caracara (Milvago chimango - Vieillot, 1816), from southern Brazil, as a new natural host for Trichomonas gallinae (Rivolta, 1878).

Leucocytozoon toddi and Haemoproteus tinnunculi (Protozoa: Haemosporina) in the Chimango caracara (Milvago chimango) in southern Chile [PDF]
Memorias Do Instituto Oswaldo Cruz, 2001 Two species of blood protozoans were identified from blood smears collected from 15 specimens of the Chimango caracara (Milvago chimango) on Isla Grande de Chiloé in southern Chile. These included Leucocytozoon toddi in 13 birds, including all 5 of the 4-

Did extreme nest predation favor the evolution of obligate brood parasitism in a duck? [PDF]
Ecol Evol, 2022 We used an experimental nest predation study to test the idea that high nest predation rates coupled with high success by laying in aggressive host nests played a role in the evolution of brood parasitism in the enigmatic black‐headed duck. Experimental duck eggs in untended nests suffered massive rapid predation, while eggs in tended nests of the ...

Combining point counts and autonomous recording units improves avian survey efficacy across elevational gradients on two continents. [PDF]
Ecol Evol, 2021 Using avian surveys conducted in comparable, high elevation, temperate mountain habitats at opposite ends of the Americas (British Columbia, Canada, and southern Chile), we show combined ARU and point count methods are among the most efficient and accurate approaches to capturing diversity.

Tree-Cavity Denning of Güiña (<i>Leopardus guigna</i>) and Breeding Productivity From Camera Trap Records. [PDF]
Ecol EvolTree cavities are critical habitats for numerous vertebrate species. We report the first evidence of güiña breeding in a tree cavity, with insights from camera trap surveys in south‐central Chile's temperate forests. These findings enhance our understanding of the species' natural history, breeding behavior, and habitat preferences.

Recognition of Predator Type and Risk Level in Azure-Winged Magpies (Cyanopica cyanus) Through Visual and Auditory Cues. [PDF]
Ecol EvolIn this study, we demonstrated that Azure‐winged Magpies (Cyanopica cyanus) uses both visual and auditory cues to detect different predator types and to assess the risk level during the non‐breeding season. In particular, a stronger anti‐predator response was observed to Domestic Cats than to the less frequently encountered Common Kestrel and two non ...

The Chimango Caracara (Milvago chimango), an additional fisher among Caracarini falcons [PDF]
Biota Neotropica, 2009 The Caracarini falcons are among the most versatile birds of prey, and their variable diet includes fishes, which may be taken as carrion. However, fishing behaviour is described for two species. Here we describe the Chimango Caracara (Milvago chimango) fishing at an estuary in Chile, Pacific coast of South America.

Perineuronal satellite neuroglia in the telencephalon of New Caledonian crows and other Passeriformes: evidence of satellite glial cells in the central nervous system of healthy birds? [PDF]
PeerJ, 2013 Glia have been implicated in a variety of functions in the central nervous system, including the control of the neuronal extracellular space, synaptic plasticity and transmission, development and adult neurogenesis.

Animal Cognition, 2014 Exploration represents an important way by which organisms evaluate environment information. The decision of whether or not an animal should investigate environmental changes may influence the extent to which animals learn about their surroundings and cope with habitat modifications.
