Data from: Multi-species sensory networks and social foraging strategies: Implications for population decline in procellariiform seabirds

Multi-species sensory networks, where different species prioritize
different sensory modalities and then use heterospecific information in a
likely non-cooperative fashion, may allow animals to improve foraging over
large areas for cryptic prey. We test this hypothesis in procellariiform
seabirds that forage in mixed flocks, where both prey odors and visual
cues provided by other foraging hetero- and con-specifics might improve
success rates. Using agent-based models, we explored the impact of social
strategies on olfactory foraging for Antarctic krill (Euphausia superba).
Our results suggest that social foraging enables species with different
sensory adaptations to achieve similar success rates. Additionally, our
results indicate that foraging is more successful in mixed-species rather
than single-species flocks, where individuals can monitor the activity of
other birds that are using different sensory foraging strategies than
themselves to find prey. These results suggest that sensory-based foraging
networks may be more critical to their survival than previously assumed.
Finally, we show that success rates decrease at low population densities.
As seabird populations continue to decline, understanding and preserving
these social foraging networks may be essential for their conservation and
ecological success. Overall, our study provides insights into the critical
role of multi-species sensory networks for foraging success, wherein
different species have different sensory adaptations for locating prey.
While we used empirical anatomical and behavioral data specific to
procellariiforms to inform our models, our approach and results may have
broader implications for other species as well.
