I’ve now had time to check the phenology chart for Barn Swallows on the “Birds of North America Online” species account…it shows some small number of past nesting records this late in the season with all nestlings fledging by around September 10th at the latest. So these young are right on the cusp of as-late-as-possible for Barn Swallows who must then migrate much further south.


These images are of active nest in a barn just south of Ashland at about 2200′ elevation. The days are warm and the horse manure supplies plenty of flying insects. But this seems very late. The adult birds are rearing four young Barn Swallows. The Handbook of Oregon Birds says the species is in migration from mid-August through October. These nestlings have a lot of growing and maturing to do if they’re going to begin to fly hundreds of miles within the next eight weeks. I wish them well.


  1. We had a pair of Barn Swallows try a second brood here in North Bend, but they pushed all four out of the nest in Mid-August … presumably realising they’d started too late.
