Another really busy week split between the office and field. The easterly winds didn't really produce the diversity of migrants I was hoping for, so waders were given lots of attention given the favourable tides down at Virkie and Scatness. Bird of the week goes to the Booted Warbler found on Wednesday evening at Sumburgh Farm. Unlike most Booteds I have seen, it proved extremely elusive for much of the time but having a) got up at the crack of dawn to be the first there and b) worked out its circuit and its favoured haunts, I waited and waited and finally got some nice shots. Very many thanks to Jim Irvine of Sumburgh Farm for letting me wander so freely across his land in order to take these pictures.
