WATCHING GIANTS - THE SECRET LIVES OF WHALES

Kelsey, a scientist and author (Saving Sea Otters), meditates in 20 linked essays on the resident and visiting cetaceans-including whales, dolphins and orcas-of the Gulf of California. To convey what's known and suspected about the underwater mammalian lifestyle, Kelsey interviews dozens of contemporary ocean scientists-Exequiel Ezcurra, Bruce Mate, Fred Sharpe, husband-and-wife team Hal Whitehead and Linda Weilgart-and places their research in context alongside data on African elephant herds, antelope and wildebeest feeding strategies, the behaviors of predators and (especially) the dynamics of her own family (mom to two young daughters, Kelsey's first chapter is titled "Extreme Motherhood").
