[Mark Garland photographed this Cave Swallow showing signs of molt. Michael O'Brien's comments on it follow: ". . . this is typical for a first year Cave. All seem to be in suspended molt right now, in varying stages. This one has new (dark) inner primaries and old outers. Some are a bit farther along, others still show full juv primaries. Adults would have all fresh primaries right now. As far as I know I have never seen an adult Cave Swallow in Cape May."]
