Hi, all. [Chipping Sparrow just flew over at 4:10 a.m., Mountain Daylight Time, i.e., during astronomical dawn, eastern Boulder County, Colorado, USA, Tuesday, July 23rd.]
Cool observations and speculation from Ken. One point of clarification: In contrast to the situation with Ken's thrashers, tanagers, etc., I wouldn't say that western Chipping Sparrows are dispersing at night between broods. Rather, they're dispersing at night from their one brood (I think) and their faraway molting grounds. It's been slow tonight, with just two Chipping Sparrow flight calls since about 2:30 a.m. But it was nice to hear the first nigh-migrant Lark Sparrow of the season, about 20 minutes ago.
