Relationship between spatial and social phenotypes in an avian scavenger

Area of Science:

• Behavioral Ecology
• Spatial Ecology
• Animal Social Networks

Background:

• Animal interactions range from incidental encounters to deliberate social engagements.
• Understanding the interplay between spatial behavior and social dynamics is crucial for assessing individual fitness and population health.

Purpose of the Study:

• To investigate how space utilization correlates with social standing in avian scavengers during flight, feeding, and roosting.
• To differentiate between incidental and non-incidental social interactions and their relationship with space use.

Main Methods:

• Analyzing space use patterns in relation to social position (centrality) in flying, feeding, and roosting contexts.
• Quantifying the deviation of observed social centrality from random chance to identify non-incidental interactions.

Main Results:

• During flight, space use was primarily driven by co-movement and observed social centrality.
• While roosting, space use correlated with non-incidental social centrality, indicating the influence of social preferences.
• The relationship between animal movement and social interactions varies significantly across different behavioral contexts.

Conclusions:

• The spatial-social interface differs across contexts, with flight dominated by co-movement and roosting by social preferences.
• This nuanced understanding is vital for predicting how populations respond to environmental shifts and for effective conservation strategies for threatened species.
