Pigeons and Seagulls
I see a lot of seagulls and pigeons from my studio window, which overlooks a flat roof. Although it's in the middle of Bristol, it's a secluded space and both species of birds hang around there, and even make nests. I have spent some time eyeballing, and being eyeballed by herring gulls. Pigeons however tend to demure, being more easily intimidated.
