Dear Friend,
I am a psychiatrist based in Noosa with the University of Queensland
researching cross species group responses to injured group members.
Novelist Sir Walter Scott mentioned (fact or fiction) that crows may
kill injured group members to prevent the injured member attracting
hawks to the rookery - predator deterrence. This makes evolutionary
sense. Trawling the web I have found references to mercy killing by
crows which does not make such evolutionary sense. Konrad Lorenz
described general mobbing but I have been unable to find any
authoritative references on the predator deterrent or mercy killing
suggestions. As I have been searching for several weeks I would be most
appreciative if you were able to point me in the suitable directions
(i.e. references or people who might be able to help).
