Two swallows do not a summer make but

A swallow and a house martin might just do it. A proper post on these fabulous little chaps will come in time but the other day I had a chance due to favourable conditions to get some comparison shots of swallows and house martins (irritatingly the sand martins of days past had done one by the time conditions favoured me). For those of you unsure of what's what.......

Swallow: "swallowtail" and black back........

House martin: Big white butt patch and stubby tail
