Can you raise sage grouse?
As the grouse’s breeding season starts this month, typically continuing through mid-May, Diamond Wings could be the first U.S. entity to breed the species in captivity. In 2017 the Wyoming Legislature passed controversial legislation authorizing Wyoming bird farms to attempt to raise sage grouse.
Why are sage grouse declining?
Impacts from development are well documented and remove habitat outright or render some of the remaining habitat nearby unusable to sage grouse due to disturbance around the infrastructure. More than 20 percent of sagebrush habitat in the Rocky Mountain region has been affected by oil and gas development and mining.
Will sage-grouse go extinct?
Now, a remarkable high desert bird, the sage grouse, is at risk of disappearing forever from this rocky wildlife sanctuary — and elsewhere across the West — because of the unrelenting spread of this horrible grass.
How long do sage-grouse live?
LIFE CYCLE: Greater sage grouse generally live from 1 to 1.5 years, but some have been known to live up to 10 years in the wild.

Why do we need sage-grouse?
Sage grouse are an important part of the web of life in the West. When we protect habitat for sage grouse, we protect habitat for hundreds of other animals including elk, deer, and antelope, creating a cascade effect for conservation.
Are sage-grouse protected?
Sage grouse, pictured here in an undated file photo, are not protected under the Endangered Species Act.
What eats sage-grouse?
From the ground, the birds have to watch for coyotes, foxes, and bobcats. Even more predators are attracted to sage grouse nests, including badgers, weasels, ravens, crows, magpies, and snakes.
What do you call a group of sage-grouse?
Traditional lekking grounds may be used for years. Although many males may display at a lek, only one or two males get picked by a majority of the females for mating. A group of grouse has many collective nouns, including a “chorus”, “covey”, “drumming”, “grumbling”, and “leash” of grouse.
What is the lifespan of the greater sage-grouse?
The life span of the greater sage-grouse is 1-4 years.
How much land does the greater sage grouse need to live?
Research suggests that a population of sage-grouse tied to a single lek might depend on more than 75,000 acres of unbroken sage, while a dispersed population with multiple nearby leks may use 250,000 acres.
Does the greater sage grouse have any predators?
Sage grouse are tasty targets for predators since they aren’t the fastest species. From the air, the greatest threats are golden eagles, along with red-tailed hawks and ferruginous hawks.
Why study sage-grouse behavior?
Our research on sage-grouse behavior is made possible by grants from the National Science Foundation and funding from UC Davis. Much of our research uses sage-grouse as a model system to address long-standing questions about how animals evolve and interact with each other and with their ecosystems.
What is a sage-grouse Lek?
Male sage-grouse gather in the spring on strutting grounds called leks ( see a video here) to court visiting females with fantastic visual and acoustic displays called struts ( see a video here , or an even cooler high-speed video here ).
How does ADM work with the sage-grouse?
For our studies of the sage-grouse, we have also collaborated with John Burt to expand the ADM system into a 24-microphone array. This array can record male signals and localize to within a meter of the sound source by measuring the time delays of the sound reaching multiple microphones.
