Sometimes you just have to be lucky. Like this evening. We were standing chatting to Mark while flocks of Black-headed Gulls passed overhead to their roost at Paxton or Grafham. All of a sudden, I caught sight of another white bird, flying the other way: a Little Egret!
If I hadn't got a lift home, if I hadn't popped in for a chat at Mark's and if we hadn't been standing outside the house... we'd never have seen it and it would never have made it onto the garden list.
