  • A Great egret (Ardea alba) feeds its chicks with fish that it regurgitated. The nest is located in the Gatorland alligator breeding marsh and bird sanctuary near Orlando, Florida. The bird sanctuary is the largest and most easily accessible wild wading bird rookery in east central Florida. Great egrets were hunted almost to extinction for its plumage, used by the fashion industry, in the 1800’s. The Aududon Society was formed during this period to push for protection for the birds from the fashion industry.

  • A juvenile bald eagle feeds on the remains of waterfowl in the Pelican Pool at the Loess Bluffs NWR (formerly known as Squaw Creek). Loess Bluffs is a wildlife refuge managed by the U.S. Fish and Wildlife Service. The 7,440-acre refuge, located in northwest Missouri is known for the migrating waterfowl, particularly Snow Geese. Fall and Spring migration can bring millions of Snow Geese to the refuge. Also, bald eagles and an occasional golden eagle pass through the area during the fall and winter months. <br />
<br />
The 10-mile auto tour around the waterways and marshes of the refuge is an excellent way to spot birds of prey, waterfowl, beavers, otters, and muskrats.

  • Only humpback whales engage in this social foraging behavior. Not all humpback whales practice this type of group feeding. One whale in the group of whales blows a curtain of bubbles to contain schools of small fish (typically Pacific herring). The whales then rush up to the surface below the encircled fish and capture the fish in their huge mouths which can be unhinged. These whales were photographed from the Alaska Marine Highway System ferry m/v LeConte near Couverden Point while traveling from Juneau to Gustavus, Alaska in the Lynn Canal.

  • A grizzly bear catches a salmon in the Chilkoot River at the Chilkoot Lake State Recreation Site near Haines, Alaska.<br />
<br />
The Chilkoot River outlet of Chilkoot Lake offers some of the best salmon fishing in Southeast Alaska. Four salmon runs are an open invitation for bears to feast on the spawning salmon. At times, the Chilkoot River Corridor has some of the highest bear activity in the state. The Chilkoot River corridor area is extremely narrow with room for an equally narrow road with few pullouts for tourists and fisherman causing traffic and congestion. This creates a serious conflict between humans and bears.<br />
<br />
Care must be taken by visitors to the area to protect themselves and the bears. Bear and human conflicts have been increasing in recent years to the point that a special human free zone was established to give bears access to the river. In addition a bear viewing platform is under development to provide a safer location for visitors to view bears feeding in the river. The area is part of the Chilkoot Lake State Recreational Site located near Haines, Alaska at the head of the Lutak Inlet in the Lynn Canal.<br />
<br />
The Chilkoot River ranks second in popularity for Southeast Alaska freshwater sports fishing. The area is also an important cultural area for the Tlingit people and site of a culture camp.

  • Rain approaches Avalanche Lake as seen from the Avalanche Lake Trail in Glacier National Park in Montana. Avalanche Lake was named in 1895 by a party including Dr. Lyman Sperry, namesake of the Sperry Glacier, who witnessed many avalanches during their stay. The meltwater from Sperry Glacier feeds the lake. Along the cliff face Monument Falls can be seen cascading down the mountain in the background. Avalanche Lake is the destination of the 4.5-mile roundtrip Avalanche Lake Trail.<br />
<br />
Glacier National Park in the Rocky Mountains of Montana encompasses more than 1 million acres. The park’s nickname is the “Crown of the Continent Ecosystem.” The park was established in May 1910. Soon after, hotels and chalets were established in the park, including the Lake McDonald Lodge. In 1932 construction began on the Going-to-the-Sun Road, allowing automobiles to traverse the park. Climate change is affecting the park. As of 2010, only 25 active glaciers remain in the park, down from the 150 that existed in the mid-19th century.<br />

  • Aialik Glacier pours down the mountains from the Harding Icefield as seen from the Aialik public use cabin on Aialik Bay in Kenai Fjords National Park in Alaska. The park, located near Seward, Alaska is known for its glaciers that flow out from the Harding Icefield, and the coastal fjords shaped by its receding glaciers. Approximately 51 percent of the park is covered by ice. The Harding Icefield, thousands of feet deep, is the largest icefield solely contained within the United States. Exit Glacier, is one of the most accessible glaciers in Alaska with easy walking trails leading up to the face of the glacier and more difficult trails leading up to the Harding Icefield which feeds Exit Glacier. Abundant land and sea life can be found within the parks boundaries including black and grizzly bears, Steller sea lions, puffins, humpback and orca whales. The park is a popular destination with sea kayakers who frequent Aialik Bay, Holgate Arm, Pederson Lagoon and Northwestern Fjord for magnificent views of the Aialik, Holgate, and Pederson glaciers. Tour companies offer boat tours out of Seward. SPECIAL NOTE: This image is a panorama composite consisting of multiple overlapping images stitched together.

  • This abandoned cabin sits in the rainforest at the site of a historic fox farm on an unnamed island in the Beardslee Islands in Glacier Bay National Park and Preserve. Several significantly damaged small cabin-like buildings are all that remain of the operation. Fox farming in Southeast Alaska began in the early 1900s with the introduction of Russian arctic foxes, which were prized for their snow-white fur. The Great Depression caused most of the fox farms to cease operations. The National Park Service reminds visitors not to take or move historical objects, and that weather-damaged structures like those found at this site should not be entered due to the likelihood of imminent collapse.<br />

  • The skull of a sea otter (Enhydra lutris) lies in the moss of an unnamed island in the Beardslee Islands of Glacier Bay National Park and Preserve. Sea otters, a keystone species of the North Pacific, were almost entirely eliminated by commercial fur hunters in the early 1900s. While they received wildlife protection in 1911, it wasn’t until the early 1990s that sea otters were observed to inhabit Glacier Bay for the first time. As the most abundant marine mammal in Glacier Bay, current estimates put the number of sea otters at 8,000. While orcas are the primary predator of adult sea otters, newborns are preyed upon by bald eagles. Sea otters are positively impacting the kelp forests as the otters protect the kelp forests from excessive grazing by the sea otters’ prey.<br />

  • These interstadial tree stumps in the Muir Inlet of Glacier Bay National Park and Preserve may look unimpressive, but they are important witnesses to the park's glacial history. Glacier Bay National Park in Southeast Alaska is the largest known repository in North America of interstadial wood from the Holocene period, which began about 11,700 years ago and continues today. Interstadial wood is not fossilized; rather, it was frozen and unfrozen when glaciers advanced and receded in the bay. The forest was sheared off when the glacier advanced but left the stumps behind. Scientists can study the rings of these trees for clues to the glacial timeline of the park. Some stumps in the park date to over 9,000 years ago, and twigs date to 13,700 years ago.<br />

  • In 2001, a 44-year-old pregnant whale was struck by and killed by a cruise ship in the waters of Glacier Bay National Park and Preserve. As part of a legal settlement with the cruise line, her skeleton was used to make one of the world’s largest humpback interpretive displays. The whale, given the name “Snow”, was 45.5 feet long and weighed 35 tons at the time of her death. Snow’s death contributed to research that helped settle the scientific question of how long humpbacks can live, now believed to be up to 96 years.<br />

  • A kayaker kayaks past a small iceberg floating in the Muir Inlet of Glacier Bay National Park. This piece of glacial ice is technically not an iceberg due to its small size. The size category for an iceberg is huge, with the height of the ice must be greater than 16 feet above sea level, a thickness of 98-164 feet, with a coverage area greater than 5,382 square feet. Next size down is bergy bits (height less than 16 feet above sea level but greater than three feet), then growlers (less than three feet above sea level - the size of a truck or grand piano), and then brash ice.<br />
<br />
The piece of ice is from the retreating McBride Glacier. Recent research determined that there is 11% less glacial ice in Glacier Bay than in the 1950s. Still, even with the earth’s rapidly changing climate, Glacier Bay is home to a few stable glaciers due to heavy snowfall in the nearby Fairweather Mountains. <br />

  • Dung beetles roll a ball of bison dung along a road in the Tallgrass Prairie National Preserve located in the Flint Hills of Kansas near the towns of Strong City and Cottonwood Falls. Dung beetles feed on manure, using it provide housing and food for their offspring and for prairie and pasture nutrient recycling. A male and a female beetle will work in a pair to roll a ball of dung away from a manure pile. They then will bury the ball as a home for their young. Drawn to manure by odor, a beetle will fly up to 10 miles in search of the right manure. Studies have also shown that dung beetles use the Milky Way as a directional bearing to navigate. Tallgrass Prairie National Preserve is the only unit of the National Park Service dedicated to the preservation of the tallgrass prairie ecosystem. The Tallgrass Prairie National Preserve is co-managed with The Nature Conservancy.

The turtles are known to travel 700 miles from the main Hawaiian Islands to the Northwest Hawaiian Islands to lay their eggs and nest. The turtles are protected under Hawaii state and federal law as a threatened species. This turtle was photographed near the Hapaialii heiau in Keauhou on the Big Island of Hawaii.

  • A juvenile bald eagle (Haliaeetus leucocephalus) flies in the Chilkat River Bald Eagle Preserve along the Chilkat River near the village of Klukwan in Alaska. 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.

  • Steller sea lions (Eumetopias jubatus) relax at their haul-out on South Marble Island in Glacier Bay National Park and Preserve. Large male sea lions will compete to mate with females at outer coast locations in the park, with the unsuccessful or immature bulls gathering at haul-out areas like South Marble Island.<br />
<br />
South Marble Island is also known for its colonies of nesting birds, including tufted puffin, pelagic cormorant, black-legged kittiwake, pigeon guillemot, and common murre.<br />
<br />
Glacier Bay National Park is located in southeast Alaska. The park is also an important marine wilderness area known for its spectacular tidewater glaciers, icefields, and tall coastal mountains. The park, a popular destination for cruise ships, is also known for its sea kayaking and wildlife viewing opportunities. <br />
<br />
Glacier Bay National Park is home to humpback whales which feed in the park's protected waters during the summer, both black and grizzly bears, moose, wolves, sea otters, harbor seals, Steller sea lions, and numerous species of sea birds. <br />
<br />
The dynamically changing park, known for its large, contiguous, intact ecosystems, is a United Nations biosphere reserve and a UNESCO World Heritage site.

  • The skull of a sea otter (Enhydra lutris) lies in the moss of an unnamed island in the Beardslee Islands of Glacier Bay National Park and Preserve. Sea otters, a keystone species of the North Pacific, were almost entirely eliminated by commercial fur hunters in the early 1900s. While they received wildlife protection in 1911, it wasn’t until the early 1990s that sea otters were observed to inhabit Glacier Bay for the first time. As the most abundant marine mammal in Glacier Bay, current estimates put the number of sea otters at 8,000. While orcas are the primary predator of adult sea otters, newborns are preyed upon by bald eagles. Sea otters are positively impacting the kelp forests as the otters protect the kelp forests from excessive grazing by the sea otters’ prey.<br />

  • This abandoned building sits in the rainforest at the site of a historic fox farm on an unnamed island in the Beardslee Islands in Glacier Bay National Park and Preserve. Several significantly damaged small cabin-like buildings are all that remain of the operation. Fox farming in Southeast Alaska began in the early 1900s with the introduction of Russian arctic foxes, which were prized for their snow-white fur. The Great Depression caused most of the fox farms to cease operations. The National Park Service reminds visitors not to take or move historical objects, and that weather-damaged structures like those found at this site should not be entered due to the likelihood of imminent collapse.<br />

  • A kayaker eases their way down a quiet section the Current River, one of two rivers that make up the Ozark National Scenic Riverways in Missouri. The Current River is the most spring-fed of all the rivers in the Missouri Ozarks. The river is a favorite with paddlers who enjoy the cold crystal clear water from springs that feed the Current River, including Cave Spring, Pulltite Spring, Round Spring, Blue Spring, and Big Spring. The scenic river is lined with rock ledges, caves, gravel bars and bluffs.<br />
<br />
The Ozark National Scenic Riverways was established in 1964, making it America's first national park area to protect a wild river system. The Ozark National Scenic Riverways, which include the Current and Jacks Fork rivers, is known for its caves, springs, sinkholes and losing streams. Visitors can enjoy water activities, such as floating, canoeing, tubing, swimming, and fishing. Additionally, there are opportunities for hiking, horseback riding, and wildlife viewing. Over 130 miles of waterways and 300 identified caves exist within the park.

  • Hundreds of unidentified flies hover above a bison (Bison bison) during sunset in the Regal Prairie Natural Area located in Prairie State Park. <br />
<br />
Among the flies that are a pest to bison are horn flies (Haematobia irritans). As many as 500 to 1,500 horn flies will feed on the blood of a bison 20 to 40 times a day.<br />
<br />
Prairie State Park, located near Liberal, Mo. is Missouri’s largest remaining tallgrass prairie. The park’s nearly 4,000 acres is home to bison and elk. Panoramic hillsides of wildflowers such as prairie blazing star, sunflowers, and Indian paintbrush provide a canvas of color. In the fall, prairie grass such as big bluestem and Indian grass may tower as high as 8 feet tall. <br />
<br />
Tallgrass prairie once covered more than 13 million acres of Missouri’s landscape. Today, less than one percent remains. The prairie at Prairie State Park remains because the rocky land was too difficult to plow, which protected it from being farmed. Hiking, animal viewing, camping, birdwatching, and photography are some of the activities that the park affords. <br />
<br />
The Regal Prairie Natural Area is a 240-acre state natural area within the park that is especially noted for its wildflower display. The Nature Conservancy and the Missouri Prairie Foundation provided funding for the purchase of much of the park’s acreage. The area was dedicated as a state park in 1982.

  • Dillard Mill, located along Huzzah Creek, is one of Missouri’s best-preserved water-powered gristmills. The mill, now part of the Dillard Mill State Historic Site, was built in 1908 and was in business until 1956 making it the longest-running mill of its kind in the state. Since 1977, the Dillard Mill State Historic Site has been leased by the L-A-D Foundation to the Missouri Department of Natural Resources for management by Missouri State Parks.<br />
<br />
Formerly known as the Mischke Mill before its restoration was completed in 1980, Dillard Mill uses an underwater turbine rather than a water wheel.<br />
<br />
Pictured is a detail of the roller mill manufactured by Barnard and Leas Manufacturing Co. A roller mill is used for the “first break” where the husk was sheared from the wheat kernel. <br />
<br />
When it was an operating mill, area farmers would bring their grain to the mill to be ground into flour and eventually livestock feed. Most of Dillard Mill's original machinery is still operational. Visitors can see and hear the sounds of the machinery and turbine just as millers did over a hundred years ago. <br />
<br />
Dillard Mill State Historic Site was listed on the National Register of Historic Places in 2015.

  • Rachel Wheat, a graduate student at the University of California Santa Cruz, photographs a salmon carcass from which she has taken a bear saliva DNA sample from 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. EDITORS NOTE: Images of Wheat capturing bald eagles for the bald eagle portion of her study are available here: http://denglerimages.photoshelter.com/gallery/Bald-eagle-research-Chilkat-River-eagle-migration-study/G0000GTyPvah7eiQ/<br />
