Grote meeuwen vangen grote vogels

Three cases of predation of large gulls on wild, healthy large birds are described. In June/July 1986, during a period of about ten days, a Lesser Blackbacked Gull caught a recently fledged Black-headed Gull daily, by grabbing it by a wing basis and drowning it. In March 2011 a Yellow-legged Gull easily caught a Feral pigeon. In June 2011 a Herring Gull caught at least six recently fledged Jackdaws within a couple of days. Capturing large and healthy birds by gulls is an uncommon but known phenomenon, although preys usually involve freshwater- and/or seabirds. Jackdaws as prey have also been described previously, but Feral pigeons have not. This is remarkable, as they are usually proliferating in coastal cities, where large gulls are usually common as well. Both gulls, Jackdaws and pigeons are often considered a pest. However, the more gulls breed in cities, the greater the chance that individuals start specializing on such defenseless, easy and abundant prey as pigeons.
