When I came home this afternoon, I heard a strange birdcall [a high-pitched "EEuh", but not like the hawk cry movie producers always use, "EEEer"] I know it was a raptor, its attitude while perching gave that away, but in the fading light, I couldn't make out its coloring. From the size, I thought it might be a Cooper's. Does anyone know of a site that has birdcalls? Maybe I can figure it out that way. The @#$% killed one of my older hens, a BO named Daisy. Chased her right into the field shelter (a truck topper, aka "the clubhouse") and ate her neck down to the bone. Also tore some skin from her breast. Q2: will shiny things like CDs really keep birds of prey away?
