Corvids in urban gardens are intelligent, observant birds with complex welfare needs and sometimes contentious relationships with human residents.
Urban corvids face welfare challenges from deliberate persecution including shooting and poisoning, which are often illegal but continue. Corvid traps called Larsen traps cause prolonged stress to trapped birds. Juveniles that fall from nests in urban environments frequently require rehabilitation. Their intelligence means corvids subjected to aversive experiences develop lasting aversion responses. As highly social animals, corvids that lose flock members show behaviors consistent with grief responses.
