So I went and looked at the crow’s nest from underneath, right at the base of the power pole. The nest is a lot larger than I had thought. The transformers hide much of it. It’s also difficult to see but I think I saw at least one baby crow in the nest. I’m going to bring my binoculars to work tomorrow to get a better look.
If there are indeed baby crows in the nest, the parents don’t seem to mind all the activity down below. There are people walking by and eating at restaurant patios, and most people don’t even realize the nest above them. I’ll try to get more photos tomorrow.
