Steven, The interesting things that you are noting are dataset problems in SE CO. The closest radar (what birdcast is based on) is probably Pueblo (but the radar is along the El Paso/Pueblo county borders). The further away from a radar you get, the higher up in the atmosphere you are and the less likely you are to encounter birds since they like to fly about 1-1.5km above the ground (if possible). By the time you reach that far out on a radar beam, you are usually 4-6km off the ground, so you are missing the bulk of the birds if there are any. The green dots on the birdcast map are where the radars are, and you will see quite clearly that there aren't radars very close to SE CO.
I love the folks at Cornell and appreciate what they are trying to do on a localized scale with the radar data. It is a great dataset for correlating with local upticks in birds. It isn't, however, a large-scale indicator of bird movement. They can only be reactive, not proactive to the weather patterns. Getting a deeper look into forecasting is what I am trying to do. I hope my forecasts can help in a different way than the birdcasts can. Thanks for the info.
