Galápagos: Animals Interacting

Galápagos animals strive to cope with their harsh environment. This often means struggling to find food when it is scarce, hiding from predators, and finding a mate. But much of the life of an animal involves dealing with other animals. Sometimes it is necessary to fight, but sometimes play is welcome. Some animals depend on each other through various cooperative mutualisms, while other curious animals keep a careful eye on the humans who have recently arrived in their environments. Animals are intimately part of each other’s environments, and no examination of animal behavior would be complete without understanding these relationships.

One of the most dramatic interactions among Galápagos animals is fighting—for territory, access to mates, or food. Iguanas are territorial and fight to protect their territory, and their mating success is tied to the quality of the territory they hold. Many instances of fighting ultimately are about mating. Although Waved Albatrosses form mating pairs, additional copulation is common and often a source of skirmishes. Similarly, large male Galápagos Sea Lions will protect their beaches for weeks at a time, preventing other males from gaining sexual access to females.

In the most barren and dry parts of the Galápagos, access to preferred nesting and feeding grounds can mean the difference between successfully raising offspring or not. There are often spirited disagreements over who can lay their eggs and who can feed in a given location. Not every interaction between animals is brutal, however. Galápagos animals play with members of their own species, with other animals, and even with plants and sticks.

Galápagos: Life in Motion
by Walter Perez & Michael Weisberg

The Galápagos Islands are home to an amazing variety of iconic creatures, from Giant Tortoises, Galápagos Sea Lions, Galápagos Penguins, and Ghost Crabs to Darwin’s finches, the Blue-footed Booby, and Hummingbird Moths. But how precisely do these animals manage to survive on—and in the waters around—their desert-like volcanic islands, where fresh water is always scarce, food is often hard to come by, and finding a good mate is a challenge because animal populations are so small? In this stunning large-format book, Galápagos experts Walter Perez and Michael Weisberg present an unprecedented photographic account of the remarkable survival behaviors of these beautiful and unique animals. With more than 200 detailed, close-up photographs, the book captures Galápagos animals in action as they feed, play, fight, court, mate, build nests, give birth, raise their young, and cooperate and clash with other species.

Watch male Marine Iguanas fight over territory and females; see frigatebirds steal food and nesting materials from other birds; witness the courtship dance of a pair of Blue-footed Boobies; go underwater to glimpse a Galápagos Sea Lion pup playing with its mother; and observe a baby Pacific Green Turtle enter the water for the first time. These and dozens of other unforgettable senes are all vividly captured here—including many moments that even experienced Galápagos observers may never be lucky enough to see in person.

Complete with a brief text that provides essential context, this book will be cherished by Galápagos visitors and anyone else who wants to see incredible animals on the move.
