Hello, Birders. Nice to see all the reports last night, Tuesday, August 24th, about moonwatching across the Front Range region. At 11:33 p.m. last night night, I heard an Upland Sandpiper flying over Lafayette, Boulder County. For those who seek Upland Sandpiper in Boulder County, here's the low-down on my detections of the species in the county: July 30th, 2009. 3:34 a.m. August 20th, 2009. 4:45 a.m. August 25th, 2009. 5:04 a.m. July 31st, 2010. 4:09 a.m. August 14th, 2010. 4:18 a.m. August 24th, 2010. 11:33 p.m. There's definitely a pattern emerging... Meanwhile, the nocturnal landbird flight earlier this morning, Wednesday, August 25th, was so-so in terms of number (40 flight calls per hour), but, as the day before, diversity was decent. Wilson's Warblers predominated, as is typical for this time of the year. (And I note that grounded Wilson's Warblers were constantly audible during the daylight hours yesterday and also thus far this morning; just open up your window and listen.) Otherwise, it was a hodgepoge of warbler/sparrow "seep" notes this morning, plus a few presumed Bullock's Orioles and a nice Western Meadowlark. The peak period for detectable nocturnal migration in Colorado is right now--the last week of August into the first week of September. I used to think that stormy "upslope" weather in May was the most exciting birding in Colorado, but I know it's quiet nights with light northerly winds in August. ------------------------------- Ted Floyd Editor, Birding Follow Birding magazine on Twitter: http://twitter.com/BirdingMagazine -------------------------------
