I can add Black-legged Kittiwake to the list. Our house is on the hogback above the South Bay portion of Horsetooth Reservoir west of Fort Collins, in Ponderosa Pine woodland. In Dec., 2018, the Kittiwake (first found by Nick Komar, I think) was viewed by folks (including me) for a few days in the vicinity of the Spring Canyon dam, which is visible from our house and deck. The bird also spent time in the South Bay, directly below our house, and I was able to view it from the deck through my scope for several minutes.
We've lived here for 35+ years, and our yard list is now at 162 spp. Lots of highlights:
- 6 hummer spp., including a male Anna's hummer that spent the summer of 1992 at our house (documented with a Dave Leatherman photo in American Birds!), and additional visits by a male for multiple days each in Oct., 1996 and Nov., 2008. Also, a male Ruby-throated for a few days in May, 2012.
- All 3 Rosy-finches visiting repeatedly our first winter in the house (1988-89). I thought, "This is great! I'll have them here every winter." Unfortunately, they haven't been seen here since then!
- Ash-throated Flycatchers nesting (in bluebird boxes), with 3 fledglings in 2010 and 5 in 2011.
- Barrow's Goldeneye on Horsetooth Reservoir, viewed from the deck.
- Red-breasted x Black-headed Grosbeak hybrids, multiple times.
- Lazuli x Indigo Bunting hybrids, multiple times
- Northern Goshawk chasing Pinyon Jays at a feeder.
- Juniper Titmouse, Nov. 2001 - Feb. 2002.
- A White-winged Dove that I saw out the window while I was teaching a remote class from home over Zoom in 2020. Students were amused when I suddenly paused the class to go and observe the bird!
The adventure's not over!

Hi all,
Here's an updated list that reflects the most recent additions to the combined list (Greater Sage Grouse, Sharp-tailed Grouse, Harris's Hawk, Zone-tailed Hawk, and Gyrfalcon). A special thank you to the WSBN birders who have contributed lists. It's great to be able to include your sightings and Western Slope specialty species as well.
Total species on the combined list is now 391.
I'm still plugging away at matching names of viewers to species, trying to be sure that all who have contributed are included on the list. I hope to be done soon and be able to pass it on to Bryan so that it's accessible via his Google sheet.
Thanks!
Thomas
