Peter,
We visit in Estes Park spring, summer, and fall every year.
For many years, Cliff Swallows have nested under the roof overhang of the power plant at the west end of Lake Estes. This year, there have been no active nests there when we have visited. Also, I always have seen Cliff Swallows flying in the lake area, along with Barn, Tree, and Violet-green Swallows, during the nesting season. This year I have not seen any Cliff Swallows around the lake on our visits in May and July. My only observation of Cliff Swallow in the Estes Park area this season was on May 26 at Lily Lake, south of Estes on Highway 7.
Looking at eBird bar charts for 2025 for the Lake Estes and Matthews-Reeser Bird Sanctuary eBird hotspots at Lake Estes, it appears that sightings of Cliff Swallow at Lake Estes are down considerably compared to the previous 4 years.
Maybe someone who is resident in Estes Park can chime in to confirm or correct my observation.

Hi birders,
I live in Superior and have enjoyed watching several largish colonies of Cliff Swallows (dozens of nests) around town for many years. However, starting this year, several of these nesting areas are completely unoccupied even though the mud nests themselves are still largely intact. Has anyone else seen something like this? Any idea what might cause it?
Thanks,Peter RuprechtSuperior
