This is pretty interesting. I am sitting here doing my thing when I hear this screaming coming from my back porch. I get up to investigate only to find three of these black birds the size of Robbins doing strafing runs on my 150lb Rott for the food in his dish. I have never seen this before. Three little birds go on the offensive, attacking a BIG dog for food he's not even protecting. Damn dog is just sitting there watching.
