<font color="purple"> I thought to myself; why don’t these birds just fly to Florida or somewhere warmer. </font>
I don't know if this is universally true. When I lived in MD for many years, I took pleasure observing the birds in my feeders. What I noticed after careful observation was that, while we had Blue Jays year round, they were different individuals in the summer and winter. IOW, the MD Blue Jays would migrate south, and they were replaced by Blue Jays migrating to MD from somewhere further north. So, even though it was cold, to the winter Blue Jays it was warm (warmer than where they came from).
