It's often under-appreciated by visitors just how scarce Black-headed Gulls are at the Bill: being more inshore/inland birds they're rarely present amongst feeding gulls offshore, whilst most migrants take the short-cut over Chesil Beach and Portland Harbour; this year, just 13 migrants were logged passing the Bill during April and, up until today, 31 had passed during May - quite why 28 should suddenly pass by today in a steady procession of small groups in utterly benign conditions defied obvious explanation but was one of those silly little things that keeps you looking and pondering © Martin Cade:
