“Through learning gulls’ nutrition, we will be able to be told extra about their behaviour, their function in ecosystems and the pressures they face in a converting global,” she stated.

UK seabirds face threats from warming oceans, overfishing and avian flu.

Gull populations are in decline, with a number of species on the United Kingdom pink record of conservation worry.
