I couldn't decide who was eyeing up who for breakfast but as the birds were bigger than the cats, I ran out, grabbed a broom and only succeeded on shooing them to the roof of my house. These vultures are not afraid!
Eventually they flew across the back yard and sat in a tree for the rest of the day.
But...I did some research and found they are Black Vultures, not Turkey Vultures. The difference is...Black Vultures will kill small animals for food. Yikes!
DH was not home but I told him all about it that evening. The next morning I went out, and there they were again, perched on the gutter overlooking the cats. Who, bless their little courageous hearts, were growling at them again.
I had to dash off to work but DH heard the growling and fluttering of wings, grabbed his gun and took a shot through the bathroom window at them. He winged one of them so quickly ran out to deliver the mercy shot. The other has not been back since.
Or as my DH said, nevermore...nevermore.
