Hello, Birders. As Allan Burns noted a little while ago, practically everybody seems to have seen a Broad-winged Hawk in eastern Colorado in the past week or so. So, for yet another datum, Hannah and I saw an adult at the base of Gregory Canyon, Boulder County, early yesterday evening, Tuesday, May 4th. To sorta follow up on Allan's point (..."but a further contribution to the trend"), a great way to contribute to our understanding of, say, the spring Broad-wing flight in Colorado is to enter your bird notes into eBird (http://ebird.org). For example, here's a map of eBird records of Broad-winged Hawks in the Front Range region: http://tinyurl.com/29pyke9 You can click on each occurrence (a red or yellow stickpin) and get details on the sighting. Also, if you play around with the tabs, you can generate graphs and charts that bring out some really interesting patterns in the data. For example, compare the Colorado plot of Broad-wing abundance through the year with the continental plot for abundance through the year. The differences are striking. ------------------------------- Ted Floyd Editor, Birding Follow Birding magazine on Twitter: http://twitter.com/BirdingMagazine ------------------------------- _________________________________________________________________ Hotmail has tools for the New Busy.
