Evaluación de la efectividad de las trampas de tipo “walk-in” para capturar una rapaz neotropical, el Chimango (Milvago chimango), en diferentes ambientes [PDF]

, 2017
En muchos estudios sobre aves rapaces se requiere la captura de los individuos y la selección de la técnica de trampeo más efectiva puede ser crucial para alcanzar los objetivos del estudio.

The shapes of bird beaks are highly controlled by nondietary factors. [PDF]

Proc Natl Acad Sci U S A, 2016
Bird beaks are textbook examples of ecological adaptation to diet, but their shapes are also controlled by genetic and developmental histories. To test the effects of these factors on the avian craniofacial skeleton, we conducted morphometric analyses on

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

Ecol 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.

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.

Recognition of Predator Type and Risk Level in Azure-Winged Magpies (Cyanopica cyanus) Through Visual and Auditory Cues. [PDF]

Ecol 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 ...

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

Austral 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 ...

Learning and innovation in urban yellow mongooses (Cynictis penicillata)

Ethology, Volume 129, Issue 11, Page 600-611, November 2023., 2023
We presented yellow mongooses, Cynictis penicillata, with problem‐solving puzzle boxes of increasing complexity in three urban locations with differing levels of human contact. The mongooses were able to solve the problem at each stage of complexity, but took the longest during the second and fourth stages of complexity.

Object neophilia in wild herring gulls in urban and rural locations

Journal of Avian Biology, Volume 2023, Issue 1-2, January/February 2023., 2023
Living with increasing urbanisation and human populations requires resourcefulness and flexibility in wild animals' behaviour. Animals have to adapt to anthropogenic novelty in habitat structure and resources that may not resemble, or be as beneficial as, natural resources. Herring gulls Larus argentatus increasingly reside in towns and cities to breed

The first fossil record of a bone assemblage accumulated by New World vultures (Gruta do Presépio, Holocene, southern Brazil)

Boreas, Volume 51, Issue 3, Page 684-697, July 2022., 2022
Here we present the first fossil record of a bone assemblage that could have been accumulated by New World vultures (Cathartidae). The bone remains were found in an archaeological rockshelter called Gruta do Presépio (GPR), located in the tropical rainforest environment of Santa Catarina State, southern Brazil, where groups of hunters and gatherers ...
