Big Pacific: The Yellow-eyed Penguin, A Model Parent

From page 32 of Big Pacific:

The Yellow-eyed penguin is one of the world’s rarest penguins. Equally dependent on land and sea, it is — unusually for a penguin — not a colonial bird, instead breeding in pairs in temperate coastal forests, scrubland and cliffs. Yellow-eyed penguins are model parents. They mate for life, working together to build a shallow nest of twigs, grass and leaves, often in the tangled roots of trees. The female typically lays a single clutch of two eggs, which both birds take turns incubating for up to 51 days. This division of labor continues after the chicks hatch, when one parent will return to sea to feed while the other stays on duty with the youngsters. Despite such devoted parenting, only 18 of 100 penguin chicks survive their first year of life due to predation, disease and human disturbance.

Throughout the summer, Yellow-eyed penguin chicks are always under the watchful eye of one of their two parents.

Although they appear keen-eyed, the birds are shortsighted on land, as their vision is adapted for underwater conditions. When foraging at sea they may travel as far as 25 kilometers (15 miles) from land and dive to depths of 120 meters (400 feet) in search of small to medium-sized fish, squid and crustaceans.  The Yellow-eyed penguin habitat lies within the Roaring Forties — a band of ocean below the 40th parallel south where large tracts of uninterrupted ocean allow high winds to develop. Returning to shore often involves negotiating tumultuous seas, after which the birds face a lengthy inland walk over rocks and through pastureland and forest to reach their nesting site.

Big Pacific: Passionate, Voracious, Mysterious, Violent
By Rebecca Tansley

The Pacific Ocean covers one-third of Earth’s surface—more than all of the planet’s landmasses combined. It contains half of the world’s water, hides its deepest places, and is home to some of the most dazzling creatures known to science. The companion book to the spectacular five-part series on PBS produced by Natural History New Zealand, Big Pacific breaks the boundaries between land and sea to present the Pacific Ocean and its inhabitants as you have never seen them before.

Illustrated in full color throughout, Big Pacific blends a wealth of stunning Ultra HD images with spellbinding storytelling to take you into a realm teeming with exotic life rarely witnessed up close—until now. The book is divided into four sections, each one focusing on an aspect of the Pacific. “Passionate Pacific” looks at the private lives of sea creatures, with topics ranging from the mating behaviors of great white sharks to the monogamy of wolf eels, while “Voracious Pacific” covers hunting and feeding. In “Mysterious Pacific,” you will be introduced to the Pacific’s more extraordinary creatures, like the pufferfish and firefly squid, and explore some of the region’s eerier locales, like the turtle tombs of Borneo and the skull caves of Papua New Guinea. “Violent Pacific” examines the effects of events like natural disasters on the development of the Pacific Ocean’s geography and the evolution of its marine life.

Providing an unparalleled look at a diverse range of species, locations, and natural phenomena, Big Pacific is truly an epic excursion to one of the world’s last great frontiers.
