From: Fission-fusion dynamics over large distances in raven non-breeders
Co-occurrence of every combination of two individuals (A + B) at a single food source (Austrian study site). The percentage of days each raven was present is always shown for one individual of each combination on the x-axis (IDs A) and for the other one on the y-axis (IDs B). The z-axis represents the percentage of co-occurrence of these individuals. The different colors show the combinations of classified presence patterns: locals (loc), frequent visitors (freq) and rare visitors (rare). Only ravens that were present at least 10 times are included (N = 126).
