The night flight over Lafayette, eastern Boulder County, earlier today, Friday, August 30th, was really good. I listened and recorded from about 1:30 until 6:00 a.m. There were several 15-minute periods when birds were going over at close to 300 flight calls per hour, which is excellent for us in Colorado; the flight was strongest from around 2:30 to 3:15 and then again from 5:00 to 5:45. Many were Chipping Sparrows and I believe Brewer's Sparrows; also Yellow and Wilson's warblers; and a nice Lincoln's Sparrow. I heard one Solitary Sandpiper, too, and saw a nighthawk, presumably a Common.
After sunup, a Peregrine Falcon flew over Greenlee Preserve in Lafayette.
