Well done pete, ringing swallows seems a bit of a challenge but I must admit the real challenge would be (for me) to get the buggers out of the nest , I only have small thick "sausage" fingers good for grabbing hold of someone but not much else .I guess it would all come down to practice. the only time ive handle swallows/house martins is when they've hit a window ect..beautiful little birds, still amazes me how they make that epic journey . keep posting I find this fascinating .
