Subject: [cobirds] Re: Late nesting barn swallows
Inspired by Scott's posts about these swallows, I went for a short "walk"
at a local shopping center in Greenwood Village-ish (closer to Littleton &
west Centennial than DTC) in Arapahoe County where Barn Swallows typically
nest. The first three or so nests were empty, but the fourth had young in
it. Two, I think?
