  • Two male greater prairie-chickens fight on a 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 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 />
<br />
Greater 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.

  • Two male Columbian sharp-tailed grouse fight on a lek in southern Wyoming.<br />
<br />
The Columbian sharp-tailed grouse (Tympanuchus phasianellus columbianus) is one of the seven recognized subspecies of North American sharp-tailed grouse. It is also the rarest and smallest of the subspecies of sharp-tailed grouse. Columbian sharp-tailed grouse have experienced declines in distribution and population due to overuse and development of the mountain shrub and grasslands that it favors. It is native to the sagebrush steppe of the western United States and British Columbia. First described by the Lewis & Clark expedition, Columbian sharp-tailed grouse were once the most abundant grouse in the West. Today, Columbian sharp-tailed grouse no occupy less than 10 percent of its historic range. It is currently considered a Species of Concern in several U.S. states.<br />
<br />
Like other grouse, Columbian sharp-tailed grouse congregate year after year in the spring on a small area known as a lek. Males perform highly animated dancing courtship displays to impress females to mate. These displays consist of rapidly stamping their feet at blur-like speed while keeping with their wings extended, often rotating in a circle.

  • Male lesser prairie-chickens (Tympanuchus pallidicinctus) battle each other for the prime spot on a lek 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 />
In 2023, lesser prairie-chickens officially became a federally threatened species in Kansas, Colorado, Oklahoma, and northern Texas. The population in New Mexico and western Texas was given endangered status with about half of the current population living in western Kansas.<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.<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.

The Columbian sharp-tailed grouse (Tympanuchus phasianellus columbianus) is one of the seven recognized subspecies of North American sharp-tailed grouse. It is also the rarest and smallest of the subspecies of sharp-tailed grouse. Columbian sharp-tailed grouse have experienced declines in distribution and population due to overuse and development of the mountain shrub and grasslands that it favors. It is native to the sagebrush steppe of the western United States and British Columbia. First described by the Lewis & Clark expedition, Columbian sharp-tailed grouse were once the most abundant grouse in the West. Today, Columbian sharp-tailed grouse no occupy less than 10 percent of its historic range. It is currently considered a Species of Concern in several U.S. states.<br />

Like other grouse, Columbian sharp-tailed grouse congregate year after year in the spring on a small area known as a lek. Males perform highly animated dancing courtship displays to impress females to mate. These displays consist of rapidly stamping their feet at blur-like speed while keeping with their wings extended, often rotating in a circle.

  • An adult bald eagle (Haliaeetus leucocephalus) attacks an immature (juvenile) bald eagle feeding on a salmon carcass on the banks of the Chilkat River in the Alaska Chilkat Bald Eagle Preserve. It takes four to five years for a bald eagle to develop the distinctive white head, tail and yellow beak. 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.

  • 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. 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.

  • Male lesser prairie-chickens (Tympanuchus pallidicinctus) battle each other for the prime spot on a lek near the Smoky Valley Ranch in Logan 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 />
In 2023, lesser prairie-chickens officially became a federally threatened species in Kansas, Colorado, Oklahoma, and northern Texas. The population in New Mexico and western Texas was given endangered status with about half of the current population living in western Kansas.<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.<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 />
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 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 />
<br />
Greater 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.
