Fair Isle’s long-term migration dataset: origins, innovations and analyses Fair Isle is an internationally famous site for bird migration and the observatory staff have systematically counted migrants on a daily basis for more than 60 years, producing a long-term dataset comprising over one million records of 400 species. Recently, this dataset was fully digitised and FIBO began a new project to analyse the data. The first major analysis focused on the timing of trans-Saharan migrant songbirds, and the results are reported in this paper.

Chinese Pond Heron: new to Britain A Chinese Pond Heron Ardeola bacchus was present at locations in Hythe and Saltwood, Kent, in early 2014. After review, it was accepted onto Category A of the British List. This, along with other European records prompted the review of an earlier British record: an adult in breeding plumage in Norfolk, in October 2004. That bird was also accepted, and now becomes the first British record.
