Thank you for sharing that memory. I grew up in Prince George's County, Maryland (University Park) and lived in the area from the 70s through late 2000s, and vividly remember the awful decimation from West Nile. In particular, we used to encounter many fish crows around the Anacostia River along with those magical, black-crowned night herons. Happy trails with spotting your first crow roost! I live in Maine near Mt. Desert Island and the crows and eagles battle it out. Oddly, I've seen plenty of eagle eyries but like you, few crow nests.
