Bald eagle photos published in Natural History

by

November 2013 Natural History magazineImages of bald eagles photographed by yours truly on the Chilkat River in Alaska have been published in the November 2013 edition of Natural History.

The magazine, founded in 1900, publishes stories on expeditions and research by curators at the American Museum of Natural History and other science and natural history museums. My favorite science guy, astrophysicist Neil deGrasse Tyson, writes occasionally for the magazine.

One of the two images published was an image of over 50 bald eagles sitting in the cottonwood trees along the Chilkat River. The magazine’s art director, Steve Black presented that photo as a double page spread. The other photo was of group of eagles feeding on salmon. The images and short story by Erin Espelie about why the bald eagles come to the Chilkat appeared in the “Natural Moments” feature that appears in the front portion of the of the magazine. Erin’s story also included information about me and the focus of the work that I have been doing in southeast Alaska.

The November 2013 issue of Natural History is available at Barnes & Noble stores now or as an in-app purchase for the iPad at the iTunes store .

Chilkat River bald eagles and Alaska winter landscapes – 2012

by

After posting my research photos, I received a few questions from worried friends wondering if I shot any bald eagle or landscape still photos — the kind that people like to “ooh and ah” over. Well, yes, not to worry. I did shoot a few. If you saw my previous blog post on the bald eagle researchers working on the Chilkat River you know that most of my time was spent with them.

One thing I neglected to mention in that post is that in addition to recording hours and hours of audio, I also shot video. Actually, a lot of video. I’m confident to say that I shot more video than stills. While it is a bit overwhelming at the moment to have to edit, but I’m looking forward to working with that material. I’ll talk about my reasons for my emphasis on video in a future blog post.

So here is a slideshow of a few of my favorite still photos from my trip last October – November on the Chilkat River in the Alaska Chilkat Bald Eagle Preserve near Haines, Alaska.

Hanging out with research bald eagle number 24

by

Continuing with my recent post on bald eagle research being conducted on the Chilkat River in the Alaska Chilkat Bald Eagle Preserve, I thought it would be interesting to show a video clip and photos of an eagle that is part of a different research project.

Research bald eagle number 24 is one of three eagles that are part of the research study being conducted by Steve Lewis of the U.S. Fish and Wildlife Service in Juneau, Alaska. The study is examining the effects of eagle nest removal at the Juneau airport (approximately 95 miles away). Number 24 is one of a pair of bald eagles who were nesting near the pond airstrip where float planes land and take off.

A year earlier, I photographed research bald eagle number 88, a control bird in that study. Research bald eagle number 88 originally had a GPS tracking pack, but later lost it. Interestingly, I photographed research bald eagle number 24 very near were I had previously photographed research bald eagle number 88.

Unlike the eagles I recently photographed that were part of Rachel Wheat‘s study, research bald eagles numbers 24 and 88 have a patagial tag (green wing tag) along with the solar powered GPS tracking satellite transmitter. The transmitter’s antenna can be seen sticking out of the eagle’s feathers to the right of the green patagial tag.

What’s for lunch?
How about dandelions says the black bear

by

An American black bear (Ursus americanus), eats dandelions just outside the boundary of Kluane National Park and Preserve along Yukon Highway 3, near Gribbles Gulch in the Yukon Territory, Canada. While most of a black bear’s diet is vegetation, black bears are omnivores meaning that they eat both plants and animals (grasses, berries, roots, insects, fish and mammals). Black bears typically weight 200 to 600 pounds. Not all black bears are black in color -- some are brown or even blond. They are most easily distinguished apart from grizzly bears by the lack of the pronounced shoulder hump found in a grizzly bear. The black bear is not considered to be a threatened species, though care to keep them from getting human food and garbage is needed to protect them from conflicts with humans. Kluane National Park and Reserve is known for it's massive mountains, spectacular glacier and icefield landscapes including Canada's tallest peak, Mount Logan (19,545 ft.). The 5.4 million acre park is also known for it's wildlife, including grizzly bears, wolves, caribou and Dall sheep. The park is one of a collection of U.S. and Canadian national and provincial parks that form the largest international protected area in the world. Kluane National Park and Reserve was selected as a UNESCO World Heritage Site for being an outstanding wilderness of global significance.

I’m starting to Edit my way through a backlog of images from last summer, in particular images taken in the Yukon and Haines, Alaska areas. I’ll be posting more about these trips in the future. In the meantime, one photo made me laugh as I was quickly looking through the images.

It was this photo of a handsome American black bear (Ursus americanus) that fleetingly made eye contact with me mid-chew while it was eating dandelions. The spot where I photographed the black bear, just outside the boundary of Kluane National Park and Preserve along Yukon Highway 3 in Yukon, Canada, had looked promising for bear photos. Several days earlier I had spotted a grizzly munching lunch in the same dandelion patch. The openness of the patch and accessibility made me think it was a spot worth returning to. I’m glad I did. I watched the black bear eat for close to 40 minutes. I’m certain the bear knew I was watching him through my long 600mm telephoto lens but he ignored my presence for the entire time, except for this one split second when he gave me a glance. He was much more concerned about eating and … taking a nap. During much of this unusually pleasant day, as I spent my time watching, the bear snoozed. Which was something I would have liked to do, but probably not smart idea in bear country. Eventually the black bear woke up and went back to business and munched some more, and in the process, collecting fluffy white dandelion seed pods on his jet black fur.

While most of a black bear’s diet is vegetation, black bears are omnivores; meaning that they eat both plants and animals (grasses, berries, roots, insects, fish and mammals). Black bears typically weight 200 to 600 pounds. Surprisingly, not all black bears are black in color — some are brown, brown or even blond. They are most easily distinguished from grizzly bears by the lack of the pronounced shoulder hump found in a grizzly bear. The black bear is not considered to be a threatened species, though care not to allow them to get human food and garbage is needed to protect them from conflicts with humans.

On all my trips to the far north, the one thing I always wish for is to see bears. I can’t think of a trip when I haven’t seen one, often seeing them everyday while backpacking or sea kayaking. It was another great day. Here are some more images as proof.
