Today we caught more rodents! We have been trapping at this site for 2 days and will try to catch more mammals tomorrow morning, before moving on to the next site at Cooks lake. We trapped 2 mice and 2 vole in the morning and 3 vole in the afternoon for a total of seven mammals. Yesterday, we caught 2 mice and 1 vole in the morning and 3 vole in the afternoon. What does this tell you about the vole population (think about times caught)? What about the population of deer mice? The area that we are measuring is a 50 meter by 100 meter area. Can you estimate the population density of the site and explain your reasoning?

Today we caught some mammals! Two mice and four voles (small rodents).
In my transect, I caught the only female mouse of the day! It is a deer mouse. In this video, I am helping to determine the gender and the weight of a vole. It was a female. We then took them back to the site where we caught the mammals and released them so they could find their way back home. We put the mice and voles into mazes when releasing them to determine how smart they are. How would we determine whether they are smart though a maze? Would they go fast or slow? Do you think the mice and voles are smart this time of year? Why? Why does Dr. Christina Bueshing cut the fur of the vole we are about to release?

Today we made traps to try and catch our first mice and voles. Our goal is to find the population density of these mammals in an area called east port. We first filled the traps with hay and food and set them out over night. How many do you think we will catch? We wanted to put the traps in places where the mice or voles might be. Where do you think that is? Can you think like a mouse? We will be checking the traps two times a day, once in the morning and once in the evening. Why do you think that is?
