Hi -
I found your contact info on a Colorado Rare Birds report, am sending you this information in case you are interested.
I spotted a common loon on Baseline Reservoir over the weekend, and after doing a little research realized that it may be somewhat unusual to have a loon here. I tried posting it on eBird, but it is not showing up in the listings for some reason. Anyway, I thought you might be able to notify people who might be interested in taking a look. I was out there Saturday, went back on Sunday for another look. It seemed pretty happy diving for food, and didn't seem too bothered by the boat traffic on the lake.
There was a nice bald eagle out there for a little while as well, which was also a treat.
