I’ve been putting down small amounts of sunflower seeds for the voles , only to find it gone , usually just after i’ve given up watching. i did see a Shrew taking the seeds , which i thought was odd since they’re supposed to be carnivorous. As i was just about to go out today i glimpsed a vole nabbing some seeds , so i grabbed the camera and caught the greedy critter red handed , its amazing how many seeds they can shift in a short time !!
