• When here in the Outer Hebrides and looking at a bird, have you ever wondered how rare it is? The status of all species can vary enormously from island to island. How rare is Shoveler on Barra, has Stock Dove been seen on Harris, does Dotterel occur on Benbecula in the autumn, and how common is Blue Tit on North Uist? Well, fret no longer! The Status and Distribution of birds here on the Outer Hebrides has been completely updated and summarised for every species and each of the main islands and outliers.

Stable isotopes reveal the importance of seabirds and marine foods in the diet of St Kilda field mice


Eyes and Ears Everywhere
An interesting study into the relationship between the St. Kilda Field Mouse and the seabird colonies.


the conclusion of the study is as follows:
This study highlights the power of stable isotope analyses to study the diet of cryptic species like mice, and in this instance the hitherto poorly studied endemic St Kilda field mouse. Our results indicate that mice breeding close to a large seabird colony are isotopically distinct from mice elsewhere on the island and that these values varied in line with the temporal availability of seabirds. The evidence is clear that mice on Carn Mor feed on seabirds, although it is unknown whether this is from scavenging carrion or predating live birds, or viable eggs. Further work is required to study the true nature of the interaction between St Kilda field mice and the threatened seabird populations in this small and remote island archipelago.
