Attended a really interesting GWT course on Small Mammals and their ecology at Greystones Farm. After some background on British small mammals, we learned how to set Longworth traps and run surveys and also recognise small mammal bones from Barn Owl pellets. On a wet day our traps looked inviting, lined with bedding hay and furnished with a variety of different foods - for vegetarian voles, omnivorous mice and carnivorous voles - but placing them for a couple of hours in the afternoon we didn’t catch anything. However, some traps lines that had been set early in the morning were more successful, and we caught 2 Common Shrews, a Bank Vole and (very exciting!) a Water Shrew that had been foraging quite far from its normal riverside habitat. The mammals were sexed, weighed and returned back, none the worse for the experience. I thoroughly recommend the course and will definitely go on some more GWT courses. It was really good to see these mammals alive and close up.
