Request for info on cliff swallow colonies

[Nora Covy]

Hi all,

I am a master's student at UNC and am currently working on a project involving parasite loads in cliff swallow nests. I am searching for colonies in Larimer County and Boulder County that are located on natural cliff faces or bridges in rural areas and that would be accessible with an extension ladder. So far, I have located a handful of colonies around Horsetooth Reservoir, Bobcat Ridge, and Red Mountain Open Space, but I would really like to increase my sample size. Do you all have any suggestions of other places I can check? Your help would be hugely appreciated! Thanks and enjoy the holiday weekend. :)
