Galápagos: Courtship, Mating, and Birth

Adapted from pages 128-138 of Galápagos: Life in Motion:

From an evolutionary point of view, nothing is more critical than finding a mate, having offspring, and ensuring that those offspring can survive to reproduce. To this most important of activities, Galápagos animals devote enormous time and effort. For some species, courtship and mating have evolved into elaborate rituals involving song, dance, and the exchange of gifts. Others meticulously prepare nests—in the trees, on the rocks, or under the beach— for sheltering their young. For many species, parental care is freely given, sometimes over many years. But for a few unusual species, parental care is just as easily revoked, sentencing offspring to certain death.

Galápagos mating rituals can be quite elaborate. Swallow-tailed Gulls pairbond and build nesting platforms out of pieces of coral. Boobies sing, dance, and exchange gifts prior to mating. And the rare Flightless Cormorants engage in a beautiful, synchronized courtship dance both before and after mating.

The birds and reptiles of the Galápagos employ many strategies to protect their eggs and their offspring. Some birds build nests in trees, others on bare rocks. Some nests are built out of leaves and twigs, others out of bits of coral and urchin spikes, and still others are simply large holes under the beach. Once they lay eggs, some parents, like Blue-footed Boobies, keep a close watch on them. Others, like Pacific Green Turtles, leave the eggs and offspring to fend for themselves.

 

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.
