Had a "big" day on today's birdwalk with 24 species in just over 2 hours (26 if I were to include Red Crossbills and Pine Siskins I saw just outside the Visitor Center as I was leaving for the meeting place - in addition, I only count species observed while actually birding with the visitors and only if at least half of them see the bird, too). This total (24) equals the best from last summer and the total number of species seen in all the walks this year already exceeds last year's total (38 vs. 36). While I have seen them in the park when not "birdwalking", a pair of Rock Wrens, found just over the edge of the rim, were new additions for the walks. The day might have been even better if a couple of raptors would have given us longer looks (best guess was Northern Goshawk and Peregrine Falcon - I'm just not confident enough to say for sure).

Here's the complete rundown: Turkey Vulture, White-throated Swift, Northern Flicker, Say's Phoebe, Steller's Jay, Clark's Nutcracker, Common Raven, Violet-green Swallow, Mountain Chickadee, White-breasted Nuthatch, Pygmy Nuthatch, Rock Wren, Western Bluebird, Mountain Bluebird, Townsend's Solitaire, American Robin, Yellow-rumped Warbler, Grace's Warbler, Western Tanager, Green-tailed Towhee, Chipping Sparrow, Dark-eyed Junco, Cassin's Finch, Brown-headed Cowbird.
