  • The rising tide envelopes a rock encrusted in blue mussels and acorn barnacles on a beach near the Klotz Hills and not far from Maquinna Cove in Muir Inlet in Glacier Bay National Park and Preserve in southeast Alaska. Prominent in the background is Mt. Wright which is located at the mouth of Adams Inlet. EDITORS NOTE: The use of a slow shutter speed smoothed the action of the waves.

  • A male lesser prairie-chicken (Tympanuchus pallidicinctus) races across a lek to protect his spot from other males on the Hoeme Family Farm and Ranch in Gove County, Kansas. Prairie chickens return to the same lek year after year to mate. Males attempt to entice female lesser prairie-chickens with a showy mating display on a lek <br />
<br />
During courtship on a lek, males inflate their red esophageal air sacs and hold erect pinnae on each side of the neck. They rapidly stomp their feet making a drumming-like sound. The booming call of lesser-prairie chickens, amplified by the air sacs, can be heard as far as a mile away.<br />
<br />
Lesser prairie-chickens are threatened by climate changes (drought or too much rain) and habitat loss. In particular, habitat loss caused by wind energy development. Prairie-chickens need large expanses of open grassland without tall objects (like wind turbines or power lines and power poles) that provide a raptor to perch on. As of early 2022, the U.S. Fish and Wildlife Service has placed a status of proposed threatened or proposed endangered species. A ruling is expected in the summer of 2022.<br />
<br />
Lesser prairie-chickens are found in Colorado, Kansas, New Mexico, Oklahoma, and Texas with about half of the current population living in western Kansas.

  • A male greater prairie-chicken races across a lek to defend his spot on the lek in Mitchell County, Kansas.<br />
<br />
The greater prairie-chicken or pinnated grouse (Tympanuchus cupido) is known for its mating ritual by males called booming. In the spring, males gather on leks, also known as booming grounds, in which they defend small areas on the lek to perform their mating displays for visiting females. This display includes extending their orange eye combs, lowering the head, raising two tufts of feathers on the neck, and pointing the tail slightly forward while stamping their feet rapidly. They also expand their bright reddish-orange air sac to produce a booming-like sound that can be heard up to a mile away. In addition, males will vigorously defend their territory on the lek by chasing, leaping in the air, and dramatic fighting. <br />

  • Water gushes from Blue Spring into the Blue Spring branch before quickly emptying into the Current River. Blue Spring is Missouri’s sixth largest spring with a discharge of 90 million gallons of water per day. The azure blue depths of Blue Spring reach 310 feet making it Missouri’s deepest spring and among the deepest in the United States. Dissolved rock such as limestone and or dolomite, along with the influence of the deep depth of the spring and the blue of the sky, give the spring its blue color. <br />
<br />
Blue Spring is a Missouri Natural Area, a special designation given to areas of outstanding beauty or scientific interest. The area around the spring is managed by the Missouri Department of Conservation, while the Current River and the surrounding area are administered by the National Park Service as part of the Ozark National Scenic Riverways. Blue Spring is located just off the Current River near Owls Bend, an area that historically supported a mill that produced gunpowder and a river ferry which was the only way across the Current River until 1975.<br />
<br />
The area surrounding Blue Spring was once used for a lodge and retreat until 1960.
