Social interactions and information use by foraging seabirds.

Area of Science:

• Behavioral Ecology
• Animal Behavior
• Ornithology

Background:

• Seabirds utilize social cues for locating prey, ranging from simple attraction to complex learning.
• Colonial nesting, extended juvenile periods, and interspecific associations highlight seabirds' capacity for social information use.

Purpose of the Study:

• To review how seabirds use social information at colonies and at sea for foraging.
• To discuss variations in social information use across species and individuals.
• To explore how social interactions influence foraging success and coexistence.

Main Methods:

• Literature review synthesizing studies on seabird foraging behavior.
• Analysis of social cues, learning mechanisms, and foraging tactics in seabirds.
• Examination of factors influencing social information use in foraging decisions.

Main Results:

• Social interactions are a critical and beneficial component of seabird foraging.
• The extent and manner of social information use vary significantly among species and individuals.
• Aggregations can lead to foraging gains by altering dynamics and promoting coexistence through behavioral modifications.

Conclusions:

• Seabirds actively use social information for foraging, with variation in the degree of utilization.
• Competitive interference can be mitigated by behavioral adaptations, enabling foraging benefits from group living.
• Disruptions to social networks from environmental changes pose a significant threat to seabird populations by impacting food acquisition and information transfer.
