Behaketaren xehetasunak
Phenomenal movement, perhaps unprecedented in the UK (?), birds were moving constantly while we were out between 2220 and 2310 and sporadically on the tape afterwards. Presumably birds leaving the Irish Sea and heading across the Peak District towards the North Sea. The wing whirrs were often more prominent that the calls suggesting many groups weren't vocalising. Oliver Metcalf and I are hatching a plan to try and derive some sort of estimate of numbers but thousands doesn't seem implausible given the numbers wintering off North Wales.
