"Hold on!" cried Peter. "I thought you said Sally Sly is a member of the Blackbird family. I don't see what she's got to do with Goldy the Oriole."

"You don't, eh?" exclaimed Jenny. "Well, for one who pokes into other people's affairs as you do, you don't know much. The Orioles and the Meadow Larks and the Grackles and the Bobolinks all belong to the Blackbird family. They're all related to Redwing the Blackbird, and Sally Sly the Cowbird belongs in the same family."

Peter gasped. "I--I-- hadn't the least idea that any of these folks were related," stammered Peter.

"Well, they are," retorted Jenny Wren. "As I live, there's Sally Sly now!"

Peter caught a glimpse of a brownish-gray bird who reminded him somewhat of Mrs. Redwing. She was about the same size and looked very much like her. It was plain that she was trying to keep out of sight, and the instant she knew that she had been discovered she flew away in the direction of the Old Pasture. It happened that late that afternoon Peter visited the Old Pasture and saw her again. She and some of her friends were busily walking about close to the feet of the cows, where they seemed to be picking up food. One had a brown head, neck and breast; the rest of his coat was glossy black. Peter rightly guessed that this must be Mr. Cowbird. Seeing them on such good terms with the cows he understood why they are called Cowbirds.
