Book Description
Field studies of the life history and ecology of killer whale populations off Canada's west coast have been conducted annually since 1973. These studies are based on the identification of individual whales from photographs of permanent, natural markings. In this report, we summarize abundance trends in the northern resident killer whale population between 1974 and 2014, and provide an updated photo-identification catalogue of individuals. In 2014, the northern resident population was composed of 290 whales. The population has grown at an average mean annual rate of 2.2% since 1974. Continued population monitoring by photo-identification is a key research activity in the recovery strategy for this threatened population.

Book Description
Fully revised edition with updated information on the surviving members of the orca pod. In 2014, marine biologist Dr Natalie Sanders joined the crew of the research vessel Silurian to seek out Britain's West Coast Community of orca and study them before we lose them forever. Though this orca pod has delighted scientists and whale watchers for years, we still know relatively little about them, and what we do know comes mostly from citizen science and chance encounters. But what is abundantly clear is that pollution, entanglement, military sonar and climate change continue to have an enormous impact on whales and dolphins and other marine life throughout the world's oceans. This book is a must-read for anyone interested in the marine world in this age of climate change. A captivating yet poignant account, it takes the reader from the Western Isles of Scotland to Vancouver Island and elsewhere. It also delves deep into the history of our relations with these beautiful and sentient creatures to explain what their loss means and how we can avoid similar tragedies in the future.

Book Description
The three authors have been studying killer whales since the 1970s, when they began photographing dorsal fins and the gray saddle patches at the base of the fins in order to identify individual whales. They present the latest information on killer whale natural history; suggestions on how, when, and where to best watch killer whales; and a catalog of some 300 photographs of "resident" killer whales which can be used to identify individuals and their family groups. 10.75x9" Annotation c. by Book News, Inc., Portland, Or.

Book Description
Experience the hauntingly beautiful world of orcas, and discover the stories that unfold when humans enter oceans alongside them. Winner of the National Outdoor Book Award by the NOBA Foundation, Honorable mention for the Sigurd Olson Nature Writing Awards by the Northland College When intrepid biology student Hanne Strager volunteered to be the cook on a small research vessel in Norway's Lofoten Islands, the trip inspired a decades-long journey into the lives of killer whales—and an exploration of people's complex relationships with the biggest predators on earth. The Killer Whale Journals chronicles the now internationally renowned science writer's fascinating adventures around the world, documenting Strager's personal experiences with orcas in the wild. Killer whales' incredible intelligence, long life spans, and strong family bonds lead many people to see them as kindred spirits in the sea. But not everyone feels this way—like wolves, orcas have been both beloved and vilified throughout human history. In this absorbing odyssey, Strager traces the complicated relationship between humans and killer whales, while delving into their behavior, biology, and ecology. She brings us along in her travels to the most remote corners of the world, battling the stormy Arctic seas of northern Norway with fellow biologists intent on decoding whale-song, interviewing First Nations conservationists in Vancouver, observing Inuit hunters in Greenland, and witnessing the dismantling of black market "whale jails" in the Russian wilderness of Kamchatka. Through these captivating stories, Strager introduces us to a diverse cast of characters from Inuit elders to Australian Aboriginal whalers and guides us through the world's wild waters, from fjords above the Arctic circle in Norway to the poaching-infested waters off Kamchatka. Featuring astonishing photographs from famed nature photographer and conservationist Paul Nicklen, The Killer Whale Journals reveals rare and intimate moments of connection with these fierce, brilliant predators.
