Checking the traps

Today we checked our traps once in the morning and once in the afternoon. We trapped and released a total of 7 red-backed voles. 5 of them had markings on their fur which meant that they had already been caught by a previous team in September. This is good news, because it means those voles have survived the winter with enough food and without being caught by a predator. 2 of them had not been caught before, and Christina cut the tips of a bit of hair on their sides in order to leave a mark (this does not hurt the vole). Why do you think it is important to know which mice have been caught before and which ones are new? Here's a picture of Christina weighing a deer mouse, it weighed about 23g: We also took a walk to look for field signs and came across a lot of coyote scat on the trail. Since they are carnivores, their scat has lots of fur and bones in it which they cannot digest. This is a close up of what it can look like!
