Will someone answer a question about birds?
We have a robin that repeatedly attacks and flies into our picture window,then flies off to a nearby post and re-attacks every few minutes. We have put artificial snakes, coiled ropes, wind chimes etc up but no luck. In fact I think the bird laughs at our attempts. Please does anyone have a suggestion on how to frighten this bird away? A shotgun is NOT the answer that I am looking for….. something reasonable please. No other birds are doing this.
