With a little help from my (Psittacidae) friends [PDF]
Learning & Behavior, 2020 Understanding the distribution of and mechanisms underlying prosocial behavior in other species has been hampered by methodological differences among studies, questions about animals' interpretations of the designs, and low phylogenetic diversity. Brucks and von Bayern's recent report that African gray parrots are proactively prosocial reiterates the ...

The 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

Population recovery of an endangered macaw enhances long‐distance seed dispersal via stomatochory
Oikos, EarlyView.Seed dispersal by large, mobile vertebrates plays a key role in shaping plant spatial dynamics and community structure. However, how variation in animal population size influences the magnitude and spatial scale of seed dispersal remains poorly understood.

Variable social organization and breeding system of a social parrot revealed by genetic analysis
Ibis, Volume 168, Issue 2, Page 451-464, April 2026.Social organization and contributions to reproduction vary widely within and between species that breed in groups. Such variation often arises from the process of group formation, which drives patterns of relatedness and hence the degree of social conflict and co‐operation between group members.
