Many years ago when we first moved into this house there was a neighbor next door who put out bird seed. We ended up getting 100’s of black birds sitting on all the roofs. They even started building nests under my eves. I WILL NOT put out a bird feeder.
We drove by a house in our town that had 20+ vultures in the front yard. What were they feeding them???
They chopped down all their trees shortly after.
