Lynn Sherr, the award-winning correspondent for ABC TV’s 20/20 newsmagazine, went to Africa for the first time in 1973 and fell in love — with giraffes. “They were a dazzling, unexpected revelation: gawky, graceful anomalies; cool, gentle giants dressed in golden, stained-glass coats.

“Bet Yer Blue Boons” is one of the most agile and intelligent cutting horses in the world, a true champion. “Rio,” a spectacular polo pony, is a gifted athlete able to sprint at 30 miles per hour, then stop suddenly and turn on a dime. “Chamont” has the natural talent and physique of a great dressage horse, but also at times a timorous personality that puts a question mark on his future success. Each of these remarkable animals shares an astonishing trait: the ability to implicitly trust, and perform complex tasks in tandem with, a human partner working toward a common goal. This teaming of horse and rider is arguably the most sophisticated and intriguing example of human-animal cooperation. NATURE explores and illuminates this absorbing phenomenon in Horse and Rider.
