Kenneth Balcomb, senior scientist at the Center for Whale Research Friday Harbor, Washington, explains the connection between the Southern Resident killer whales (orcas) and chinook salmon.
Katie Colbert, a naturalist at the Sunol-Ohlone Regional Wilderness, shares with us how she tracked dozens of Northern Pacific rattlesnakes and what surprised her about their movements and behaviors.
A few weeks ago, scuba divers in Lake Tahoe found the body of a man who had drowned in the lake 17 years ago. Still in its wetsuit, the body was very well preserved. Because the water in this high alpine lake is so cold, decomposition is very slow. This fact has spawned rumors, the most famous of which involves Jacques Cousteau and still makes me shudder, years after I first heard it.
Watch as thousands of prehistoric horseshoe crabs take over a beach in Delaware.
This week millions of viewer’s eyes will be turned to "Shark Week", the Discovery Channel's most popular program. With shows like "Top Five Eaten Alive", "Killer Sharks and Rogue Sharks", the program continues to dish up blood, teeth and fear, while perpetuating the irrational perception that sharks are killing machines.
Once an exotic product associated with royalty and overfishing, caviar is now being farmed sustainably right here in California.
California’s grasslands are some of the most heavily invaded habitats in the state. As the climate changes—temperatures increase and water becomes scarcer—the conditions will favor exotic grasses, which will become even more prevalent.
They are an icon of the Pacific Northwest, stirring a mix of fascination, awe and affection. Thousands of people come to the San Juan Islands in Puget Sound just to catch a glimpse of the Southern Resident orcas that call these waters home.
It’s clear that in the wild, orcas seem to have a pretty universal rule: don’t attack humans. The reason would appear to be both biological and cultural.
Scientists are looking for clues in killer whales' aquatic droppings as they try to determine why their numbers remain so low in Puget Sound. To sniff out these floating data dumps, researchers have turned to a furry colleague named Tucker.
Nothing excites whale researchers and whale fanatics more than seeing a new calf born into the pod. However, researchers have learned that calf survival rates are incredibly low, especially for the orca’s first born. The mother’s young calf often dies because of something the mother passes on to her offspring—PCBs.
