This study assesses whether African grey parrots can learn and apply a 'larger-than' rule in size or quantity discrimination, finding limited transfer but individual variation in rule acquisition.

The paper identifies convergent and lineage-specific genomic changes in sugar-feeding birds through genome and transcriptome analyses, revealing adaptive mechanisms in metabolic pathways.

This study shows subadult macaws copy non-preferred actions better than adults in problem-solving tasks but are less likely to imitate specific actions, suggesting age-related differences in social learning.

This study shows undomesticated blue-throated macaws can imitate intransitive actions after observing others, indicating third-party imitation exists outside humans.

This study shows dolphins can encode information for future use, demonstrating prospective memory and episodic-like memory capabilities.

This study surveys video footage to assess vocal production learning (VPL) across parrot species, finding evidence of VPL in 136 of 163 surveyed species and identifying socio-ecological factors associated with its evolution.
