The last thing Nancy Ellis-Bell expected to descend on her life was a neglected, too-tall, smart-mouthed, one-legged, blue-and-gold rescue macaw named Peg Leg. And yet, it made perfect sense. A lifelong animal lover, Nancy could never turn away a stray cat, dog, squirrel, or raccoon from her California farm. But the macaw, quickly rechristened Sarah, was a whole new challenge, as Nancy, her husband, Kerry, and their furry menagerie would find out.

Initially timid of her new surroundings, Sarah soon imposed her four-foot wingspan into the family homestead—first claiming the laundry basket, then conquering a prized dresser—and achieved complete household domination. Nancy couldn’t “bird-proof” the place fast enough, and it was not long before Sarah started stealing the dogs’ toys—using her enormous beak to disembowel Ben the mutt’s treasured stuffed bear—and bathing her richly hued feathers in their water bowl. She also peppered Nancy’s phone conversations with expletive-laden outbursts. There seemed no end to Sarah’s realm, nor her destruction, and it dawned on Nancy that the entire house had slowly transformed into a birdcage.

On the other side of the coin, Sarah started to abandon her own raptor instincts when she discovered that dog food was pretty tasty and that she had a knack for “barking” (and a few other sounds that alarmed the neighbors). As they all learned to live together, Nancy marveled that Sarah had truly found a place to call home, but she sensed that there was something she could give Sarah to make her feel more complete: a chance to fly again.
