This was a family road trip visiting the Utah National Parks (sandwiched between nights in Vegas), so birding was not a priority. However, these trip lists will give you a flavor of the species possible to see at this time of year with little effort.
Zion National Park
We stayed at Cliffrose Lodge and Gardens just outside the park that was family friendly, had great gardens with lots of hummingbird feeders swarming with Black-chinned Hummingbirds and a single Rufous. It had a fantastic buffet breakfast and it's a short walk in to the park's visitor center where you can then catch a shuttle to various stops in the park. Birds seen in one day here were:
We stopped at this less well-known National Park in the hopes of Three-toed Woodpecker and Dusky Grouse. No luck with the grouse but very lucky with the woodpecker along the Alpine Pond Nature Trail where the path goes down to the pond.
There's not much to the town of Tropic itself but it is close to Bryce National Park and we stayed in pleasant Bryce Country Cabins and had a nice meal outside town at the Stone Canyon Inn which is a nice hotel about 5 miles outside of town. I managed to get out and bird before breakfast outside of town in the desert area and had:
Black-throated Gray Warbler
Bryce National Park
Grace's Warbler - campground inside Bryce National Park
Townsend's Solitaire - Sunset Point inside Bryce
Pygmy Nuthatch - Sunset Point inside Bryce
Grand Canyon National Park
All the following were seen around the North Rim Lodge which had amazing views and a nice place to stay.
