4. European Herring Gull

Serious Injury & Death

Colonially nesting gulls – especially larger species such as the European Herring Gull – can be highly aggressive towards perceived intruders. Rising garbage levels and reliable food availability in urban areas have encouraged the gulls to nest in these new habitats, increasing conflict with humans. The birds aggressively steal food from humans, causing potential injuries from the massive, razor-like bills. One boy suffered cuts to the face after a gull stole his sausage.

The birds can weigh more than 3 pounds, with wingspans around 6 feet. Territorial instincts are retained during nesting season. In 2001, a women in the UK suffered deep head wounds from an attack, and a dog was killed. In 2002, an elderly man died of a heart attack after being mobbed by gulls.
