Industrial Gulls

More than twenty years ago Lapwings started to nest on the roofs of Industrial units. At the time it was a bit of a novelty and was quickly followed ten years ago by Oyster Catchers doing the same.
A couple of weeks ago I followed an Oyster Catcher, carrying food for its young, back to the roof of my local industrial estate. When I got there I was amazed to find Herring and Lesser Black Backed Gulls all nesting on the same roof!! Upon further investigation I now find that Gulls breed on at least two other Industrial complexes in Greater Manchester.
Whilst in the hills last week I came across a Carrion Crows nest on top of a telegraph pole – another bird adopting to man! see gallery www.facebook.com/gordonyateswildlife
