Birders

and I was watching them take turns building the nest, keeping eggs warm and bringing food for over 2 weeks then one day the nest was on the ground and the eggshells smashed and empty. I didn't know what animal would do this in a city. I thought maybe a cat but my family said Black birds/Crows do that.

They came back about 2 months later and something else scared them off when they started building a new nest. We have tons of Crows around here. The poor Doves don't stand a chance.
