I hope the situation is being resolved by the poster without any endangerment to the bird.
I, too, have had bird problems in the past. A lovely male cardinal for two years wreaked havoc on my big pane kitchen window. He would crash into it several times a day. I thought for sure he'd kill himself. After two years he was gone.
But not to be outdone by the squirrels and deer - all our plums, pears and blue berries were gone before picking time was even here ! Dang, I hate when that happens.
