Birding in the Rockies
By Steve Hunter and Viviana Wolinsky
We were skiers long before we were committed birders. We admired the majestic vistas of the Colorado Rockies as we ascended the ski lifts at various resorts, and toyed with the idea of returning in the summer months. But birding put air under the wings of that fledgling thought.
With the added incentive of birding, we’ve returned a number of times in the summer months both to the slopes we had skied down and to surrounding areas near or not quite so near.

One of our nemesis birds was the White-tailed Ptarmigan, a high-altitude grouse that spends its entire life cycle above timberline in the tundra of the mountain west – the only species in North America to do so. Looking at its range map, we saw only a handful of small areas, dots even, in the lower 48. One of the larger of these small range splotches is in the northern Colorado Rockies. Drilling down in eBird, we recognized that Loveland Pass, which lies smack on the Continental Divide, was one of the few areas where the bird was somewhat regularly sighted. So several ski trips saw us eschewing the Eisenhower Tunnel (the longest mountain tunnel and highest point on the Interstate Highway System) and instead braving the curvy two-lane highway to the even higher 11,900’ Loveland Pass in search of the White-tailed Ptarmigan. The birding gods never smiled down on us at Loveland Pass, though.
Those birding gods were kinder to us in Rocky Mountain National Park (RMNP). On our first visit, though, the birding gods greeted us not with a smile but with a smirk. Was that little blob on the horizon that we saw in the scope and on the blown-up photo a rock or a White-tailed Ptarmigan? (Reasonable minds disagree….) The next visit to RMNP, however, left no doubt, as we were graced with the sight of three White-tailed Ptarmigans, including a male who flew not far over our heads, vocalizing.


Hiking above the tree line elsewhere has rewarded us with memorable moments, like the time we hiked the Shrine Mountain trail above Vail Pass, where we crossed large meadows full of wildflowers, vocalizing Pine Grosbeaks seemingly in every direction, and a pair of Canada Jays who appeared to fly over to us just to see what we were up to.…
