I was reporting what a Jefferson County Open Space ranger told us. TUVUs migrate to Colorado in the spring and hang around here into summer. Some may refer to these visitors as "locals," versus the ones who keep going north of here. For Hawkwatch, we don't count the seasonal residents as migrators; we only count the birds who continue northbound above our platform at Dinosaur Ridge. Hope that helps. -mike
