“The Kittiwake, a small seagull, could be driven off its nesting sites on the Tyne Bridge by Newcastle City Council.
The birds are at sea feeding on fish offal discarded by trawlers and when they return in the spring to nest they may find that the City Council has netted off their nesting sites on the Tyne bridge.

They used to nest in the Baltic Flour Mills but have been driven off by the cultural aspirations of Gateshead. Gateshead Council provided a nesting tower but this has been moved down river.

The renovation of the Baltic Flour Mill on the Gateshead side of the Tyne took away access to a Kittiwake breeding site on Tyneside.

Now, in response to complaints from local residents about the mess and noise from Kittiwakes, Newcastle City Council is considering netting the Tyne Bridge to prevent nesting.. IIt is clear that the Bridge has become an important breeding site for these birds. Whilst there are of course much larger breeding colonies in the UK, the Tyne Bridge is the furthest inland breeding site for Kittiwakes in the world.
