First, if you have not seen
http://hint.fm/wind/ before, it shows wind speeds and directions on a map of the country.
Currently, there is a strong, nnw direction to the east of the front range. That seems conducive to grounding migrants from north and west of CO. Has anyone noticed this?
While I'm at it, a few birds of interest have been my first Ring-billed Gull and Common Raven on campus, a large group of American Robins on Friday, two apparent Cooper's Hawk migrants, and a Wilson's Warbler killed from window impact.
Enjoying the weather,
