I’m pleased to have two of my photographs from Glacier Bay (including the photo above) published in a book by Alaska Geographic. The book, “Glacier Bay National Park and Preserve” by well-known Alaska author/photographer Kim Heacox, is a beautiful and informative book that looks at the history (natural and cultural) wildlife, and of course, the glaciers of the park.

In terms of other photographers whose work was used in the book, I am in pretty good company (Art Wolfe, Jon Cornforth, Fred Hirschman are just a few whose photography was also used).

The book is available from Alaska Geographic. If you are planning a trip to Glacier Bay or have visited the park in the past, it is a great book to have even if I might be a bit biased.

PURCHASE Glacier Bay National Park and Preserve by Kim Heacox is available online or in Alaska Geographic bookstores.

Bald eagle researcher wins prestigious NSF graduate fellowship

by

Rachel Wheat, a graduate student at the University of California Santa Cruz, poses for a photo with bald eagle (Haliaeetus leucocephalus) "4P" before releasing the bald eagle back into the wild. Wheat is conducting a bald eagle migration study of eagles that visit the Chilkat River for her doctoral dissertation. She hopes to learn how closely eagles track salmon availability across time and space. The bald eagles are being tracked using solar-powered GPS satellite transmitters (also known as a PTT - platform transmitter terminal) that attach to the backs of the eagles using a lightweight harness. A handmade leather hood is placed over the bald eagle’s eyes to keep the bird calm. Leather booties cover the bald eagle’s powerful talons to protect researchers during the process of taking measurements and attaching the GPS satellite transmitter. The latest location of this eagle can be found here: http://www.ecologyalaska.com/eagle-tracker/4p/ . During late fall, bald eagles congregate along the Chilkat River in the Alaska Chilkat Bald Eagle Preserve near Haines, Alaska to feed on salmon in what is believed to be the largest gathering of bald eagles in the world. (John L. Dengler)According to the Ecology Alaska website, one of the bald eagle researchers I photographed tagging bald eagles last fall, Rachel Wheat, was recently awarded a prestigious Graduate Research Fellowship from the National Science Foundation. The award will fund her work tagging and tracking bald eagles for the next three years. Congratulations Rachel!

One of the things I thought interesting about her work last year was that she and others on her team funded their research in a novel, non-traditional way through the crowd-funding website, Kickstarter. I thought crowd funding research was an innovative idea when she told me about it. Also somewhat unusual, she and others on the Ecology Alaska team produce a website with detailed field reports on the progress of their research and what it is like doing field research in the wilds of Alaska.

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.
