These birds vacation at their peril

University of Cincinnati scientists found that gregarious monk parakeets lose social standing during an absence. Top-ranked birds lost the most social standing while lower-ranked birds faced less aggression while rejoining the group. studied three groups of captive monk parakeets in 2021 and 2022. The new study, led by postdoctoral researcher Annemarie van der Marel, focused on testing whether social history was a critical component in structuring how the parakeets gained and maintained their ranks within their groups. Researchers were able to identify each bird’s status in the flock’s dominance hierarchy by observing their interactions and quantifying rank using networks of aggression.
