Hello, Birders. The more I think about the effects of weather on nocturnal migration in Colorado, the less certain I am of anything... Still, I cautiously predict that tonight (May 11th-12th) could be great for nocturnal migration over the Front Range region. The weather has cleared up, obviously, and a late-afternoon wind-shift is underway. With southerly winds at nightfall, all these gazillions of grounded migrants may well pick up and depart for points north and west. The exact same conditions leading up to the night of May 21st-22nd, 2008, led to a great night flight over the Front Range; see http://groups.google.com/group/cobirds/browse_thread/thread/6bde2b37b79cc818/18ecec369ed8afe?q= Helpful hint: You *have* to get out *before* the American Robins start their bedlam--probably just after 4am in most places in our area. And I reserve the right to be totally wrong about this. I am simply wary of linking nocturnal migration to the weather. On that note, I'm flattered that Steve Brown attributed to me a prediction of a "forecast for a good morning," but I didn't quite say that. Rather, my lame prediction was for a "fair bit of turnover"--that's nice, waffly language, now isn't it? Meanwhile, I'm predicting something more emphatic for tonight. And I'll probably be all wrong... :-( Ted Floyd [email protected] Lafayette, Boulder County, Colorado ------------------------------- Ted Floyd Editor, Birding ------------------------------- Please support the American Birding Association: Click on http://www.goodsearch.com/?charityid=884482 to search the internet.
