My wife puts out birdseed and as a result we get all kinds of birds, Cardinals, Blue Jays, Mockingbirds, Finches, Sparrows, Wrens, Doves and many others I can’t name. Yes we get crows and other blackbirds as well.
So if you put out free stuff, you get more diversity.................
Many people used to have lofts for racing pigeons on the roofs of tall NYC buildings. I don’t know how many, now; it doesn’t seem as popular a sport as it used to be.
