If it flies and is pretty much black, its a target. Starlings and grackles will come to feed at a feeder and throw seed out they don’t want. When the catch tray is full it goes all over the ground and in gardens. Plus they crap all over the place and its not dainty little droppings like small bird make. I wish using a .22 and bird shot was legal here in town.
Now about the robins….Ma and I ran some errands and our route took us past three different soccer complexes [this city needs to cut those soccer fields back to one, for that wuss activity] and every one was covered with robins. Ironically all three of those fields have the flowering crabs along the adjacent streets and what robins weren’t on the grass were in those trees.
Time to put the robin blocks up where they like to nest. They’re messier than heck too.
