Hello, Birders. Hannah and I heard and saw 394 Sandhill Cranes migrating high over Greenlee Preserve, Boulder County, early yesterday evening, Sept. 27th. By the way, Nick Komar said: > I wish to simply remind the listserve participants that these > flights are normal and that we probably do not need to receive > an email about each flock or sighting, now that the flights have > begun (perhaps others have a different view on this point). I have a different point of view. It is my point of view that spectacular avian phenomena are interesting and worthy of discussion. Even if we accept that Sandhill Crane flights through the Front Range urban corridor are somehow "normal" (but see below), it is fascinating that they tend to occur within extremely narrow temporal windows, sometimes involving detections of thousands of birds (and who knows how many were missed?) within a span of just a few hours. The last time this phenomenon was reported to COBirds was on a late-September afternoon/evening in 2006. Major Sandhill Crane flights over the Front Range cities are, in fact, less commonly reported to COBirds than are occurrences of, say, Laughing Gulls in eastern Colorado. I can't imagine anything more thrilling than being in one of our Front Range cities on a sunny September evening, doing yardwork or something, and then hearing and seeing hundreds of Sandhill Cranes migrating over. It's even more thrilling to know that what you have just seen is part of a broader phenomenon, being detected, being reported, and being marveled at by like-minded folks elsewhere in the region. And, again, these flights just aren't "normal." They occur rarely. I see more Glossy Ibises and Magnolia Warblers annually in the Front Range region than I see large flocks (250+ individuals) of Sandhill Cranes migrating south over the Front Range region. Bring on the reports of Sandhills! It's good stuff, good data. Submit your observations to eBird. Post to COBirds. This is as good as it gets: spectacular, short-duration flights of thousands of birds in observable active migration right over a major urban center. The phenomenon is eminently worthy of further study, formal documentation, and, most of all, enthusiastic sharing here on COBirds. -------------------------------
