There is a pigeon nesting in a multi-story car-park in town - the nest is in the far corner of the car-park, towards the back of the space, in a shallow drainage channel. She has 2 eggs, and has apparently been there for at least a week because other people have seen her... I don't know what to do! I've left my car blocking the space for now and will pick it up after work. Should I just leave her be, and check every so often? I don't want to risk catching her and moving the nest, because she might abandon it or break the eggs in the process, and even if she doesn't abandon it, her mate wouldn't be able to find her. Argh!
