Birds are smart enough to tell a good human from a bad one.
I once crossed a field that must have had a hawk’s nest, because he kept bomb diving me.
I worry all thru the winter. I haven’t come up with any design to protect the feeding area from snow, so I keep a shovel by the window to scrape the table and ladder. I also keep the window half open to the garage, with cat houses scattered around inside so that they have SOME refuge for the bad weather.
One of my videos from the Audubon sanctuary includes a hawk feeding (YUCK) that I saw on the way there. The baby bird video of the birds emerging - I stood on a ladder for over an hour on the hottest day of the year, with my camera tripod perched on big upside down flower pots. And waited. And waited. The baby emerged, flew up to the roof, and the battery died. So all I could compose was the first flight and the dream of flight of that hawk.
