Remington on Wyoming Sage Grouse Numbers 2026
Wyoming sage grouse slumped in 2026, as long-term trend line also points down Mike Koshmrl WyoFile.com Biologists, wardens and volunteers who monitor sage grouse documented fewer males strutting this spring at their Wyoming leks. That cyclical downturn indicates that population highs keep falling for a sagebrush-dependent species that continues to fare poorly in its largest stronghold. The 2026 decrease at leks — where birds gather to display and attract mates in the spring — was expected: Wyoming’s population cycles every nine years or so, and those swings are natural and part of basic sage grouse biology. More significantly, the slump downward signals that the statewide population topped out in 2025 at a level that was 26% below its 2006 peak and 15% below its 2016 peak. The trend line for these cycles points noticeably downward, and since the turn of the century, the average number of male sage grouse gathered at active Wyoming leks has fallen from 29 to 23 birds, a roughly 20% drop. “The reality is, there’s fewer average number of males per active lek at each of the [cycle] peaks,” said Nyssa Whitford, the Wyoming Game and Fish Department’s sage grouse and sagebrush biologist. What exactly to make of the numbers is up for debate among experts. Some metrics — like lek counts during troughs in the cycle — look better for Wyoming sage grouse. Yet other metrics signal sage grouse population declines over the last quarter century. Game and Fish tracks the “peak males” known to exist — it’s a measure of the highest number of males observed at all leks biologists surveyed, even if grouse counters made only a single visit.
