Thanks for all of your great questions about mammals during the family meeting yesterday. It was fun being able to see all of you when I’m so far away.

Today’s Temperature in Nova Scotia: Cloudy, then clearing. High=42 F, Low=32. Snow at the research site is beginning to melt.
We all returned to the research site at Cook’s Lake to check our traps. Dr. Christina said we should have more voles on the second day. We were excited to see more of our fury friends.
However, that was not the case. For the 100 trap set again, we only caught 2 voles, and those 2 were caught the day before! We can tell they have already been caught because we cut off a little of their “guard” hair.
Question: Do we have guard hair? Why is it important for mammals?

While we were checking our traps, I took some video of the stream that flows through the research site. Enjoy!
After lunch we set out some Passive Infrared Camera. These are the kind of cameras that are activated whenever they detect motion. They are good for checking the activity of larger animals at the site.

This afternoon, we also created nest for Mason Bees. These bees are very important in forest ecosystems. We had to cut sections of logs and then drill holes in them in order to allow the bees to make their nests.
Why did we have to drill the holes in the logs?
Why are Mason Bees different than Honey Bees?
Where did Honey Bees come from?

Later in the day we drove to another location for the opportunity to view beavers. Beaver are amazing engineers. The build their own homes called a lodge. They are crepuscular (ask you friends in Latin what that means) animals. It was a very beautiful setting and we had to set very quietly to watch them. But it was chilly!
Beavers always swim underwater to the middle of the pond, and then come up to breath. They do this in order to stay away from predators. I saw a beaver swim out, pop his head above the water, and them swim away. It was awesome to see this animal in its natural habitat.

Tomorrow, we go back to the field site to trap and release more voles or mice. Then we get to take a fun trip to the town of Liverpool, Nova Scotia.
