Cormorant??

Another walk in my local park. Not being able to travel far means that subject matter for photos is restricted. Every time I head into the park I think what on earth am I going to find that’s new!! Today, walking past the lake I spotted this bird which I think is a cormorant? Rather shocked to see it in the middle of an urban park, particularly as it had two friends with it who looked slightly different but similar. I’ve only ever seen cormorants in coastal areas or on rivers before Don’t know how long it’s planning on staying!
