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

open access: yesEcol Evol, 2019
We currently lack a comprehensive understanding of the ecological processes shaping bird migration strategies at tropical and south‐temperate latitudes. We compared the spring migration behavior of Fork‐tailed Flycatchers that breed at south‐temperate latitudes (i.e., austral migrants) and at tropical latitudes (i.e., intra‐tropical migrants) in South ...

Nonrandom filtering effect on birds: species and guilds response to urbanization. [PDF]

open access: yesEcol Evol, 2016
We evaluated the hypothesis that changes in community composition from periurban to urban areas are not a random process, and we also assessed whether there are consistent patterns of loss species and guilds across cities. Abstract Using bird survey data taken in three cities in Southern Chile, we evaluated the hypothesis that changes in community ...

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 ...

Learning and innovation in urban yellow mongooses (Cynictis penicillata)

open access: yesEthology, 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.

Problem solving of wild animals in the Wet Tropics of Queensland, Australia

open access: yesAustral Ecology, Volume 48, Issue 2, Page 313-322, April 2023., 2023
Seven species of native Australian animals (including birds, reptiles, placental mammals, and marsupials) have been observed problem solving in the Wet Tropics for the first time. Some species even solved multiple puzzle types. Abstract While many species of animals can solve food‐baited problems, most studies are conducted in captivity, which may not ...

Object neophilia in wild herring gulls in urban and rural locations

open access: yesJournal 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

Wing myology of Caracaras (Aves, Falconiformes): muscular features associated with flight behavior [PDF]

open access: yesVertebrate Zoology, 2018
Caracaras (Aves, Falconiformes, Falconidae) are Neotropical diurnal raptors that belong to the subfamily Polyborinae. The forelimb myology of this group has not been comprehensively studied or compared with that of other Falconidae.

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

open access: yesBoreas, 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 ...
