I have agree about the bread, we never fed them that, always seed, peanuts for the blue tits and fat balls which even the starlings loved. As for cats here, I was mortified when the avid hunter next door killed a swallow and dropped the poor soul in our garden even though she got it outside the property and then she took one of "our" regular visitors the ring necked doves...I just couldn't stand it so now I take bird food and feed the birds when we go to visit places near us. I know cats are natural predators of birds but I really can't bear to see it when I am feeding them in my garden.
