Sad! We had a sparrow nesting outside our window. The cats saw it. We kept the shade drawn after that. And one day… the nest was empty. Crows are in the neighborhood. I have seen them chased aggressively by red winged blackbirds. Evidently, they found mother sparrow and took her four eggs. Not even a shell was left. I don’t suppose mom will start over again. I am indeed sad. We were all anticipating the arrival of the new babies. Nope. We’re all sad around here.
