Sandwich Tern

On Sunday night (1/7) I ringed at Atlit. Nice catch of many juveniles, Little and Common Terns and a total of 62 terns caught included one Sandwich Tern. Sandwich Tern is common in winter and on migration but is fairly rare in summer. This is 2nd calendar year bird and that doesn't breed yet, and is probably roaming the seas - although it breeds not too far away: last winter we received our first control of Sandwich Tern in Israel, from Bulgaria.
Another nice anecdote: on previous Sunday I ringed a Little Tern chick with wing-length of 108mm; this Sunday it got recaptured with wing-length of 135mm - 27mm growth in one week, 3.9mm per day on average this is fast!
Thanks to Francis and Rafi for their help this night.
