Doc, robins driving me nuts too. Couple rubber snakes from $1 store seems to work....and a pellet gun.
Sometimes I get a couple dozen in the garden, they're welcome here, eat lotsa bugs. Get darn near every kind of bird in Minnysota, 'cept loons and geese. Neat to see goldfinches, bluebirds, cardinals, doves, ducks and a dozen different kinds of brown or black birds back there all at once, all eating bugs. Except the hummingbirds, but they're good to have for other reasons. Sometimes a hawk or two visits, but all the other birds disappear then. Neighbor says I had an eagle once, but I didn't see it, might have been a big hawk. Get owls at night, never see them but they can make a racket, always asking, "who?".
