"Sally Sly," snapped Jenny Wren. "Sally Sly the Cowbird. I hoped she wouldn't disgrace the Old Orchard this year, but she has. When Mr. and Mrs. Chebec returned from getting their breakfast this morning they found one of Sally Sly's eggs in their nest. They are terribly upset, and I don't blame them. If I were in their place I simply would throw that egg out. That's what I'd do, I'd throw that egg out!"

Peter was puzzled. He blinked his eyes and stroked his whiskers as he tried to understand what it all meant. "Who is Sally Sly, and what did she do that for?" he finally ventured.

"For goodness' sake, Peter Rabbit, do you mean to tell me you don't know who Sally Sly is?" Then without waiting for Peter to reply, Jenny rattled on. "She's a member of the Blackbird family and she's the laziest, most good-for-nothing, sneakiest, most unfeeling and most selfish wretch I know of!" Jenny paused long enough to get her breath. "She laid that egg in Chebec's nest because she is too lazy to build a nest of her own and too selfish to take care of her own children. Do you know what will happen, Peter Rabbit? Do you know what will happen?"
