Birding near Estes Park for AOU conference (September 24-27, 2014)
Locations near Estes Park outside of Rocky Mountain National Park that offer excellent birding opportunities during fall migration in Colorado and Wyoming are listed here. Both states offer a diversity of habitat types in close proximity to each other. In both states, it is possible to travel from grasslands to alpine tundra in only a few hours. It is important to note that in late-September many of the species that breed in the area have already migrated south. However, this is a very exciting time to go birding in this area with migrants from just about anywhere in the country coming through the region. The distances and travel times provided were acquired using Google Maps.
