The influence of anti-predator training, personality and sex in the behavior, dispersion and survival rates of translocated captive-raised parrots

open access: yesGlobal Ecology and Conservation, 2017
Predation is one of the main factors responsible for the failure of reintroduction/translocation programs. Animal's personality and sex can also influence key behaviors for survival and reproduction.

Variation in parrot jaw musculature

open access: yesThe Anatomical Record, EarlyView.
Interspecific morphological differences in some superficial jaw muscles of parrots. Abstract Psittaciformes, the order encompassing parrots and their relatives, are highly diverse and generally known for having a strong beaks used for multiple behaviors. The muscles related to the masticatory apparatus should reflect this functional complexity; however,

Osteological correlates of the respiratory and vascular systems in the neural canals of Mesozoic ornithurines Ichthyornis and Janavis

open access: yesThe Anatomical Record, EarlyView.
Abstract In birds, the neural canal houses a variety of anatomical structures including the spinal cord, meninges, spinal vasculature, and respiratory diverticula. Among these, paramedullary diverticula and the extradural dorsal spinal vein may leave behind osteological correlates in the form of pneumatic foramina and fossae, and a bilobed geometry of ...

Presence of Endangered Red-Crowned Parrots (Amazona viridigenalis) Depends on Urban Landscapes

open access: yesDiversity, 2023
Many species of plants and animals thrive in urban habitats and stand to gain from the global trend in increased urbanization. One such species, the Red-crowned Parrot (Amazona viridigenalis), is endangered within its native range but seems to thrive in ...

Endothermy, neuron counts, and other issues: Further remarks on neurocognitive evolution in fossil vertebrates

open access: yesThe Anatomical Record, EarlyView.
Abstract Last year, we challenged the view that large‐bodied theropod dinosaurs such as Tyrannosaurus rex resembled primates in cognition and behavior, a proposition made by Herculano‐Houzel in 2023. More recently, Jensen et al. have criticized our work on this topic, raising methodological and conceptual issues.

Morpho‐functional analyses of the jaw apparatus in the Blue‐and‐yellow Macaw (Ara ararauna, Psittaciformes, Aves): Adaptations to feeding behavior

open access: yesThe Anatomical Record, EarlyView.
Abstract Macaws are renowned for processing dry, mechanically resistant fruits, yet the species‐level anatomical and functional correlates of this performance remain incompletely resolved. We examined the feeding apparatus of the Blue‐and‐yellow Macaw (Ara ararauna) using an integrated approach that combines osteology, myology, and bite‐force estimates

Classifying avian drinking behaviour: ecological insights and implications in a changing world

open access: yesBiological Reviews, EarlyView.
ABSTRACT Water is a fundamental currency of life, and its availability significantly influences animal behaviour, physiology and distributions. However, our knowledge around the dependence on water for drinking and the direct and indirect mechanisms driving related behaviours remains partial in the context of changing climates. Here, we review patterns

Parrot Trade and the Potential Risk of Psittacosis as a Zoonotic Disease in Indonesian Bird Markets

open access: yesBirds
Wildlife trade, both legal and illegal, is increasingly recognized as a key factor in the rise of emerging viral infectious diseases, and this is especially apparent in Asia, where large numbers of wildlife are openly offered for sale in bird markets. We

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

open access: yesBiological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Contrafreeloading Indicating the Behavioural Need to Forage in Healthy and Feather Damaging Grey Parrots

open access: yesAnimals, 2023
Contrafreeloading (CFL) is a concept that describes the preference of an animal to work for food even when identical food is freely available, and reflects an intrinsic motivation to engage in foraging-related activities.
