Crested Tern Band and Formation Flight Behaviour

My blog has been on hold for a while as I’ve been working over the summer. However, I took some photos this morning close to my home in Seacliff, South Australia, of some Crested Terns, one of which has a leg band… ? While on the subject of Crested Terns I remember seeing formation flying behaviour that I’ve not seen other than on the Kimberley Coast…
