Though sage-grouse nonetheless dwell in all these locations, their populations have shrunk. The biggest core populations nonetheless thrive in Montana, Wyoming, Idaho, Nevada, and Oregon. Uncoincidentally, these are the identical states with probably the most intact and wholesome sagebrush landscapes.

The landscapes spanning the Higher Sage-grouse’s vary can look very completely different, however they’re very related at their core. The southernmost inhabitants of sage-grouse resides close to Alton, Utah. These birds are backdropped by Grand-Staircase Escalante Nationwide Monument’s orange and pink sandstone cliffs. Alongside the Montana and Saskatchewan border, the sky will be seen from horizon to horizon, spilling over rolling waves of sage-covered hillsides. Regardless of some scenic variations, irrespective of the place you go in sage-grouse vary, you’ll discover one important core part: sagebrush, and many it. 

Sage-grouse Dwell A Segmented Life

To know sage-grouse habitat, it’s essential know their annual life cycle. Breeding, nesting, early brood-rearing, late brood-rearing, fall, and winter are sage-grouse annual life segments. Every one requires a barely completely different habitat sort in a unique a part of their vary every year. 

Sage-grouse comply with an annual migration. They rigorously search meals, shelter, water, and canopy within the sagebrush sea to fulfill their wants at that second of their life cycle. Each bit of habitat leads them to the following one till they’ve accomplished an annual migration throughout a panorama.

Breeding Sage-grouse Habitat

Sage-grouse are often known as a “lekking” species, that means they collect communally every year from March by Could at conventional breeding websites referred to as leks. There, males courtroom females by way of strutting. Male grouse stand tall with erect tail feathers, popping yellow air sacs of their chest to an viewers of hens gathered round. Strutting sage-grouse is actually one thing to behold, an expertise I want all of humanity may witness.

For the males, lekking is all about being seen. To be able to show for an viewers, a male sage-grouse’s stage must be visually unobstructed. To fulfill this want, lek websites are open areas amongst surrounding sagebrush cowl. Ridgetops, grassy openings, burned websites, salt licks, and generally human-altered areas like airstrips, gravel pits, and sometimes cultivated fields are used as lekking grounds. Birds collect simply earlier than solar up and depart for the encircling sagebrush cowl as soon as the solar absolutely rises.

Sage-grouse Nesting Habitat

Throughout Could and June, after breeding at a lek, hens depart in search of an acceptable nest web site. Nest choice happens within the sagebrush surrounding leks and will be from one mile to some miles away. Nesting habitat is comprised of enormous sagebrush vegetation with good grass and forb (flowering plant) understories. These vegetation conceal nests each vertically and horizontally from floor and air predators. 

Hens construct floor nests in a bowl-like form. Every nest is fabricated from soil, feathers, and vegetation, and is often underneath a big, umbrella-shaped sagebrush plant.

For younger chicks to make it to maturity, they should discover habitat with an plentiful and various array of bugs and forbs. Hens usually lead their younger to areas the place they themselves had been reared as chicks. Early brood rearing takes place within the adjoining uplands close to the nest web site, with a sagebrush cover of 10 % to 25 % and a grass and forb understory of 10 % to twenty %.

Late (August-September)

Because the temperature climbs and summer season progresses, hens proceed to guide their younger throughout the panorama in quest of a really particular habitat sort: meadows with succulent grasses and forbs. Within the sage-grouse conservation world, these specific habitat sorts are referred to as mesic or moist meadows.
