Social learning in great white pelicans (Pelecanus onocrotalus): A preliminary study [PDF]
Learning & Behavior, 2020 Great white pelicans (Pelecanus onocrotalus) exhibit life-history parameters and ecological traits thought to be associated with social learning, and advanced cognitive processing more generally. In this study we investigated whether this species can acquire novel behavior socially in a foraging context.

Understanding sociality and behavior change associated with a nesting event in a captive flock of great white pelicans [PDF]
Zoo Biology, 2021 AbstractZoo‐housed pelicans are commonplace, but their breeding record is poor and little research is published on the activity patterns, as potential predictors of nesting, of captive flocks. Existing literature shows that comparative research can provide useful information for husbandry and conservation planning for pelican populations.
