Leucocytozoon toddi and Haemoproteus tinnunculi (Protozoa: Haemosporina) in the Chimango caracara (Milvago chimango) in southern Chile [PDF]

open access: yesMemorias 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-

Breeding latitude predicts timing but not rate of spring migration in a widespread migratory bird in South America [PDF]

open access: yesEcology and Evolution, Volume 9, Issue 10, Page 5752-5765, May 2019., 2019
Identifying the processes that determine avian migratory strategies in different environmental contexts is imperative to understanding the constraints to survival and reproduction faced by migratory birds across the planet.

Loss to follow-up before and after initiation of antiretroviral therapy in HIV facilities in Lilongwe, Malawi. [PDF]

open access: yesPLoS ONE, 2018
IntroductionAlthough several studies have explored factors associated with loss to follow-up (LTFU) from HIV care, there remains a gap in understanding how these factors vary by setting, volume of patient and patients' demographic and clinical ...

Did extreme nest predation favor the evolution of obligate brood parasitism in a duck? [PDF]

open access: yesEcol 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 ...

Tree-Cavity Denning of Güiña (<i>Leopardus guigna</i>) and Breeding Productivity From Camera Trap Records. [PDF]

open access: yesEcol Evol
Tree 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]

open access: yesEcol Evol
In 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 ...

Combining point counts and autonomous recording units improves avian survey efficacy across elevational gradients on two continents. [PDF]

open access: yesEcol 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.

Problem‐solving of the cylinder, tile and lever tasks by wild animals in Dryandra National Park, Western Australia

open access: yesAustral Ecology, Volume 48, Issue 8, Page 2030-2040, December 2023., 2023
Abstract Problem‐solving is an important ability that allows animals to overcome environmental challenges. As such, it is a useful measure of behavioural flexibility and could be beneficial for conservation work. However, there is currently little known about the solving abilities of many Australian species, despite the high threat of environmental ...
