IB-corvid-mob-recruitment
In crows, mobbing is a self-reinforcing recruitment LOOP: 82% of scolding events recruited a mob, averaging 6.4 birds (n=103).
Observed quantities
82% of scolds recruit a mob; average mob 6.4 birds; n=103

Outgoing
- relates to Crows acquire dangerous-human recognition mostly by HORIZONTAL social learning: naive birds that had mobbed alongside knowledgeable birds later scolded at roughly 8x the control rate (27.8% of 54 vs 3.3% of 181). recruiting a mob is the horizontal social-learning event itself
- relates to In the only directly-testable system (Physarum), body-wide contraction FAILS to globally coordinate: coordination is intermittent and slowly-modulating — wave direction reverses and amplitude drifts — which REFUTES the global standing wave. cross-domain: memory is RE-BROADCAST at each encounter, not statically held aloft
Incoming
- relates from Crow scolding of a known dangerous-human mask DOUBLED and spread at least 1.2 km over 5 years, with LINEAR (non-saturating) growth — a saturating/plateau model was statistically rejected. recruitment is the local loop that drives the linear spread
- relates from In the only directly-testable system (Physarum), body-wide contraction FAILS to globally coordinate: coordination is intermittent and slowly-modulating — wave direction reverses and amplitude drifts — which REFUTES the global standing wave. cross-domain: the imprint is RE-CAUGHT / re-broadcast each cycle, not statically held (memory falls and is re-caught)
