Abstract
Methods
- The pre-processed empirical data were provided by:
Sankey DWE, Storms RF, Musters RJ, Russell TW, Hemelrijk CK, Portugal SJ. 2021 Absence of “selfish herd” dynamics in bird flocks under threat. Curr Biol., 1–7. (doi:10.1016/j.cub.2021.05.009)
During the field experiments, a remotely controlled robotic falcon (‘RobotFalcon’) was used to attack flocks of homing pigeons (Columba livia) just after they have been released at a new location. Both prey and predator were equipped with GPS devices.
- Processed data and code used for the figures and statistics of the manuscript are stored in the Zenodo repository: DOI: 10.5281/zenodo.5889098 (the archived version of the GitHub repository PigeonsCollectiveEscape)
- The simulated data are generated by an extension of the computational model HoPE (Homing Pigeons Escape): a species-specific agent-based model, adjusted to empirical data of pigeon flocks. The model is available at the Zenodo repository: DOI: 10.5281/zenodo.5889123. The original HoPE model is first published in:
Papadopoulou M, Hildenbrandt H, Sankey DWE, Portugal SJ, Hemelrijk CK. 2022 Self-organization of collective escape in pigeon flocks. PLoS Comput Biol., 1–25. (doi:10.1371/journal.pcbi.1009772/journal.pcbi.1009772)
Simulations include one predator-agent and flocks of 8 to 34 individual pigeon-agents that demonstrate escape behavior. 'Catches' of prey by the predator are not modeled.
