Complete mitochondrial genome of chestnut-fronted macaw (Ara severus, Psittaciformes)

Mitochondrial DNA. Part B. Resources, 2017
Six genera from Arini tribe form a morphologically diverse group named macaws, which differ from other Arini in the presence of bare facial area. Macaws are further distinguished by the bare face pattern, plumage colouration and body size.

The flexible, the stereotyped and the in‐between: putting together the combinatory tool use origins hypothesis

Biological Reviews, EarlyView.
ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated

Harnessing iEcology data to uncover invasive species behaviour

Methods in Ecology and Evolution, EarlyView.
Abstract Invasive animal species threaten ecosystems, biodiversity and human livelihoods. Behavioural traits such as boldness, exploratory tendencies, learning ability and social interactions are known to influence invasion success. Yet these behavioural traits remain underexplored due to challenges in observing behaviour across large spatial and ...

Uso de recursos alimenticios por un ensamble de loros en la Selva Pedemontana de las Yungas argentinas

Acta Zoológica Lilloana
Los estudios sobre la ecología de forrajeo en loros son limitados, particularmente en la Selva Pedemontana de las Yungas en Argentina. Este estudio examinó durante dos años la dieta y el uso de recursos de seis especies de loros (Amazona tucumana ...

Holding a wing horizontal: Roles for muscles of the pectoral girdle other than the main two flight muscles

Journal of Anatomy, EarlyView.
This report explores which muscles of the pectoral girdle are employed to allow birds to hold their wings horizontally with a level aerofoil surface during a glide. Abstract Whilst many birds glide briefly with wings held horizontally, some species maintain this posture for extended periods during soaring.

Age Difference, Not Food Scarcity or Sibling Interactions, May Drive Brood Reduction in Wild Scarlet Macaws in Southeastern Peru

Diversity
Avian brood reduction was initially thought to be driven by insufficient food supply. Now it is more commonly considered a consequence of asynchronous hatching and resulting siblicide, direct filial infanticide (where parents kill specific chicks) or ...

Complete mitochondrial genome of golden conure (Guaruba guarouba)

Mitochondrial DNA. Part B. Resources, 2017
Arini tribe with 19 genera is the most diversified tribe of neotropical parrots. Six of them are classified as macaws and nine as conures. The presence of bare facial area distinguishes macaws from conures and other members of this tribe.

A New Multiplex Real-Time RT-PCR for Simultaneous Detection and Differentiation of Avian Bornaviruses

Viruses, 2021
Avian bornaviruses were first described in 2008 as the causative agents of proventricular dilatation disease (PDD) in parrots and their relatives (Psittaciformes).

Fit for purpose? Analysis of the relationship between skull, beak shape and feeding ecology in Psittaciformes

Journal of Anatomy, EarlyView.
Psittaciformes exhibit high levels of morphological diversity, particularly in skull and beak structure, previously linked to diet and body size. Although there were some levels of significance between diet and beak shape, body mass was a much stronger co‐variate. Diet is not determining beak shape within the clade.
