Hello, Birders.
For the past 2.5 hours this Saturday morning, July 20th, there's been a slow
but steady night flight of Chipping Sparrows over Lafayette, eastern Boulder
County.
In July adult Chipping Sparrows begin migrating to molting grounds in eastern
Colorado and western Kansas (and presumably elsewhere). Many migrate by night,
and their piercing flight calls, once learned, are distinctive--and one of the
characteristic sounds of summer nights in the Front Range metro region.
