  • A bald eagle (Haliaeetus leucocephalus) attacks another bald eagle with white wing tips and white talons as they fly above the Chilkat River in the Alaska Chilkat Bald Eagle Preserve near Haines, Alaska. The white wing tips and talons are caused by a leucistic condition -- a condition of reduced pigmentation resulting in white patches. These patches of white can occur while the rest of the animal is colored normal. Unlike albinism, the eye color is normal. During late fall, bald eagles congregate along the Chilkat River to feed on salmon.

  • Greater sage-grouse (Centrocercus urophasianus), an icon of the American West, once numbered as many as 16 million birds. Today, fewer than 200,000 remain. Their population is in decline due to loss of habitat from energy development and residential building in sage brush areas. A scientific study found that the population declined 55 percent from 2007 to 2013. Sage grouse are named for the sagebrush that they primarily feed on. <br />
<br />
Greater sage-grouse are an umbrella species. Conserving their habitat benefits 350 other species. Greater sage-grouse had been listed as a candidate for listing under the Endangered Species Act. In 2015, after evaluating the best available scientific and commercial information regarding the greater sage-grouse, the U.S. Fish & Wildlife Service has determined that protection for the greater sage-grouse under the Endangered Species Act is no longer warranted and withdrew the species from the candidate species list.<br />
<br />
Males are known for the large air sacks on their breasts that they inflate during elaborate courtship dances performed on leks (mating areas). Sage-grouse are the largest native grouse in North America.

  • Rachel Wheat, a graduate student at the University of California Santa Cruz, places a vial containing a sample of bear saliva on the banks of the man-made spawning channel of Herman Creek, near Haines, Alaska.<br />
<br />
Wheat is collecting DNA samples of bears from bear saliva left on salmon carcasses as part of research for her doctoral dissertation. She hopes to determine if partially-consumed salmon carcasses can serve as a viable source for bear DNA to genotype individuals. She also looking to determine a minimum population estimate for the number of bears using the Chilkoot Valley and the ratio of males to females, particularly in light of increase human presence. <br />
<br />
The bear DNA collection is part of her dissertation which looks at how the availability of salmon affects eagle movement, bear activity, and subsistence fishermen.

  • Rachel Wheat, a graduate student at the University of California Santa Cruz uses calipers to take length and depth measurements of the beak of a bald eagle (Haliaeetus leucocephalus) captured in the Alaska Chilkat Bald Eagle Preserve. In this photo she is determining the beak depth. Beak measurements and toe claw (hallux) length are two measurements that help determine the gender of a bald eagle. Female bald eagles typically have larger beaks, feet and talons. This reversal of gender size is called reverse sexual size dimorphism. 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. Assisting Wheat with the measurements by holding the eagle is Yiwei Wang, graduate student, University of California Santa Cruz.

  • Dylan Burbank (right), and David Campbell, fish technicians for the non-profit Northern Southeast Regional Aquaculture Association, Inc. (NSRAA), measure and record the weight of eggs collected from chum salmon captured at the man-made spawning channels at Herman Creek, located near Haines, Alaska.  <br />
<br />
In 2014, 2.4 million eggs were seeded into these incubation boxes. The 2013 incubation box survival rate was 90%. Without the artificial spawning, natural survival is said to be only 10%.<br />
<br />
Weighing the eggs is the way the technicians determine how many eggs are placed in the incubation boxes. After weighing, the eggs will be fertilized with the milt and then placed in the incubation boxes. Over the winter the fertilized eggs will develop into fry. The incubation process is 100% natural. Fry are not fed. Once they are big enough, the fish leave the incubation boxes on their own.<br />
<br />
The shotgun is kept handy for protection from bears.<br />
<br />
Based in Sitka, Alaska, NSRAA conducts salmon enhancement projects in northern southeast Alaska. It is funded through a salmon enhancement tax (of three percent) and cost-recovery income. NSRAA also produces sockeye, chinook, and coho salmon.<br />
<br />
Male chum salmon return to Herman Creek to spawn with female chum salmon during the fall chum salmon run. The chum salmon return to freshwater Herman Creek, tributary of the Klehini River after living three to five years in the saltwater ocean. Spawning only once, chum salmon die approximately two weeks after they spawn. <br />
<br />
Chilkat River and Klehini River chum salmon are the primary food source for one of the largest gatherings of bald eagles in the world. Each fall, bald eagles congregate in the Alaska Chilkat Bald Eagle Preserve.

  • Rachel Wheat, a graduate student at the University of California Santa Cruz (left), Steve Lewis, Raptor Management Coordinator, U.S. Fish & Wildlife Service (center) and Dr. Chris Wilmers, associate professor, University of California Santa Cruz (right) hold up the wings of a juvenile bald eagle (Haliaeetus leucocephalus) so it may be photographed. Photos of a juvenile bald eagle’s molting, particularly in the head and tail feathers, can help determine its age before it reaches maturity due to the sequential molting pattern eagles experience during the first five years of their life. 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. The latest tracking location data of this bald eagle known as "2Z" can be found here: http://www.ecologyalaska.com/eagle-tracker/2z/ . During late fall, bald eagles congregate along the Chilkat River to feed on salmon. This gathering of bald eagles in the Alaska Chilkat Bald Eagle Preserve is believed to be one of the largest gatherings of bald eagles in the world.

  • Mount Brooks, a 11,940 foot tall peak in the Alaska Range, is bathed in morning sunlight as seen from the Wonder Lake campground in Denali National Park and Preserve in Alaska. Mount Brooks, first climbed in 1952, is located at the confluence of the Muldrow, Traleika, and Brooks glaciers. The mountain is named after geologist Alfred Hulse Brooks who is credited with determining that the Brooks Range, the biggest mountain range in Arctic Alaska, was separate from the Rocky Mountains.
