Hi, sorry no one has come in on this. I'm going to hazard a guess at these. 
 
Photo 1. I think it might be a young Common Gull - Larus canus. I'm basing this on head shape, bill colour and leg colour - but I could be way off base 
 
2. Probably 'manky mallards'. difficult to tell 
 
3. Sorry no idea but I think the park has an assortment of ornamentals
