**uncommon but regular during good swallow flights but this is quite the number. accurate count and all seen very well (and some photographed): Petrochelidon swallows; dark above and light below; square tails with bright tawny rumps; pale collars; dark throats. Almost all 21 of these birds were scrutinized for CASW, despite being very early for same. Probably more than the all CLSW I've seen in Suffolk to date.
