From Worst to Best...

Wow, yesterday was quite a day! We continued to work hard at our new site, Cook's Lake, and during that work we encountered many, many ticks!

In fact, our lead scientist said she had never seen so many in one day. It was by far the worst day for them. We must have pulled off around 200! Ticks are 8 legged arachnids who live off of the blood of mammals. They like to find a nice, warm nook and then they will burrow into your skin and begin to eat. Yikes!

Thankfully, we went from the worst tick day to the best evening for beaver watching!

We sat down at the edge of this lake and waited very patiently and very quietly for the beavers to emerge. How can we tell this lake has beavers living in it? Beavers build a shelter called a lodge. Can you find the lodge in this picture of the lake?

A beaver lodge is a pretty amazing shelter.
We saw three different beavers swim out from the lodge! Sometimes they would come up onto this small patch of land to gather more sticks and other times they would swim really close to us and patrol to make sure we weren't a danger to them. A couple times one of the younger beavers got nervous and it would slap the water really hard with its tail, then dive under the surface. Apparently this is a warning signal for the others.

We also saw a different aquatic rodent called a muskrat swimming around during our beaver watching.

Today's Challenge:

How are muskrats and bea
vers similar and how are they different?

Answers to the Last Challenge:

GREAT job on the last challenge! I was so impressed with those of you who really made an effort to find out about voles, mice, and shrews.

Many of you found out a lot of the answers. Voles have smaller eyes and ears then mice. This is because mice need bigger eyes and ears to hunt for insects. Mice are
omnivores. Voles are herbivores, so they do not need those adaptations. Shrews, on the other hand are insectivorous which means they eat insects. Shrews are carnivores. They also look very different from both mice and voles.

And Whose Scat WAS That? Again, many of you did very well. That scat belonged to a...fox!

  2. The beavers are so cool , Mrs.McNulty!Here's the answer to the question you gave me;muskrats and beavers are rodents and they are different because beavers build dams and muskrats don't.

    P.S.:I really,really,really,really,really,REALLY miss you.
