The large flock of birds I think are black tailed godwits by the length of the bill and the their shape. The duck with the blue patch i assume is a teal but can someone tell me why the patch is not green ? The duck which is face on I assume is a mallard but I am not used to seeing ducks front on, out of the water. Does anyone know what the other bird is in the water form the poor rear photo ? Thank you.
