. . . before you decide it's a bad neighborhood in which to raise some birdies?
The answer, apparently, is two. The new rat-dog is part Terrier, which means anything small and flopping gets pounced on and eaten. To include two of the three cardinal chicks that fell out of the nest in the rose bush.
My Darling Wife, as sad as could be about such a random wild thing happening, took one of the dead birds right out of the dog's mouth and set it on the picnic table. The birds came and took it, and the remaining chick in the nest, and beat feet for less-hostile territory.
