Outdoor Hour Challenge: Muskrat Nature Study

This week’s nature study topic is the muskrat. Muskrats get their common name from the musk or fragrance they emit to attract a mate and to mark a territory. This is just one of the interesting facts about this mammal that you can learn from your study of the muskrat. Use the links below to get started and learn alongside your child.

Outdoor Hour Challenge Muskrats

  • Research the muskrat in a field guide or a book you find at your local library.  Here’s an online resource for this challenge: Common Muskrat.  This one is also very informative: Common Muskrat.

Outdoor Hour Challenge – Autumn Squirrel Nature Study

Outdoor Hour Challenge
Squirrel Nature Study

Use the ideas in this week’s challenge to learn more about squirrels. Hopefully you will be able to observe a real squirrel displaying his qualities of agility and ingenuity.

This post contains affiliate links to items I recommend on

Book Review  
It is always nice to have a good reference book when studying mammals…one that covers tracks and scat is very helpful. One book that I enjoy and find creates interest in this topic is the book, Tracks, Scats and Signs by Leslie Dendy. This is one a series of books that is aimed at stimulating interest in nature study, using inviting illustrations and simple to understand text. 

This is a book you will share with your children before going outdoors and then use in a follow if you find some tracks or scat. You can sketch the tracks in your nature journal or take photos to include if you wish.This book is included in Fun With Nature: Take Along Guide if already own that one.

Getting Started Suggestion:
If you already own the Getting Started ebook, complete Outdoor Hour Challenge #7. Use the notebook page in this challenge to record any mammal tracks or scat you find in your own backyard. Look up the tracks and then complete the notebook page for the animal you discover. You can add to your own field guide pages any time you find something new in your backyard.

Looking For Signs of a Squirrel – Our Rodent Nature Study

Squirrel nature study happens quite frequently at our house. We tend to have squirrels that are not shy about making themselves at home in our birdfeeders and in our trees, especially the walnut tree. I knew we had a squirrel challenge to complete this month so I have been waiting for one to come along to observe. Wouldn’t you know it? We could hear them chattering up in the tree a few times over the past few weeks but we have not actually seen our resident squirrels.

Our Outdoor Time
Kona and I completed this squirrel challenge on our own today…it was a drizzly, gray day. Kona is the squirrel hunter in our family and she will chase them along the fence line and watch them from the base of the tree. She loves a good squirrel chase. Today though there was no squirrel around.

We made use of our time by trying to find some signs of squirrels. We found quite a few walnut shells which are dead giveaway. We looked up in the tree but we couldn’t see any squirrels up there. We made our way around to the side of the house and the birdfeeder where the squirrels sometimes sit and munch on seeds. No squirrels today.

We then went around the side of the house and we saw some tracks in the mud. I think they are cat tracks.

One last tree to check out…nope, no squirrels today.

Well, we didn’t see a squirrel to observe but we ended up really enjoying our time outside. I gathered a colorful leaf bouquet, watched a flock of finches in the feeder (post to come), and we got some fresh air before it really started to rain. Successful….yes!

I did pull out the field guide and look up squirrels and read through the pages. Mr. B and I will be keeping our eyes out for squirrels as the month goes by and once the leaves are all down for the season I know we will be able to see more clearly when we hear the squirrels chattering.

Don’t forget you can study any rodent this month and there is a free printable notebook page for you to use with your Handbook
of Nature Study.Rodents included in the Handbook of Nature Study are the muskrat, house mouse, woodchuck, red squirrel, and the chipmunk.

Chipmunks or Squirrels? Our Study Using the Outdoor Hour Challenge

When you spend as much time outdoors as our family does, you eventually come across squirrels and chipmunks. Squirrels are an everyday occurrence in our yard but we do not see chipmunks at all. Chipmunks sometimes find us when we are out hiking, always when you stop to eat a picnic at Yosemite. I think the Chipmunk study as part of the More Nature Study series of Outdoor Hour Challenges will be one that is on-going since we were unable this week to observe any up close.

This past summer we had an experience where we thought we had seen chipmunks but turns out they too were squirrels.

Golden-manteled Ground Squirrel 2

This little rodent was very curious about us as we sat on the granite rock taking a rest after a long hot hike. He was not afraid of us in the least bit, begging a bite of our granola bars. We know better than to feed wild animals but he didn’t understand that people food is not good for him and insisted that he investigate our pack from the inside out.

Golden-manteled Ground Squirrel 4

We thought he was a chipmunk because of the stripes but when we got home and pulled up the field guide we realized he was a Golden-mantled ground squirrel. Our book says he is “medium sized” but we thought he was rather small compared to our other squirrels that we observe in our backyard, the Western gray squirrel and the Fox squirrel.

Golden-manteled Ground Squirrel

So how can we tell in the future that what we see IS a chipmunk? They have stripes on their head and our little ground squirrel does not.

Interesting facts:

  • Traditional hibernator- subject of much research on hibernation.
  • Eats leaves and seeds of grasses, occasionally eats nuts, roots, bulbs, and other underground plant parts.
  • Lives in the coniferous forest at elevations of 5,200 to 12,500 feet.
  • It is prey for hawks, jays, foxes, bobcats, and coyote.
  • Has cheek pouches for carrying food.
  • Digs shallow burrows (up to 100 feet) with hidden openings.
  • Cleans itself by rolling in the dirt.

Since we don’t have chipmunks in our neighborhood but we know we see them all the time when we are at Yosemite. Sounds like a good reason to take the drive soon!

Our Family OHC: Pine Cones and More About Pines

Pine Cone 11 22 10
Photo by Mr. A

Our study of pine cones started way back when I was writing the Autumn Series ebook. We gathered a few pine cones to use in the experiments suggested. We had fun soaking the cones in a bucket of water and then setting them in the sun to observe them as they dried and opened up again. Simple things sometimes make the deepest impressions and honestly, none of us had really put all the pieces together until doing the experiments. I know I took photos but they are lost somewhere on my hard drive. Could that be a sign of taking too many photos? I bet a lot of you can relate to my desire to document as much as I can about our world and that leads to lots of images to save and enjoy.

Our unofficial theme as we worked through this study became something like this:
Pine cones don’t just hold still, they are a living thing created for a specific purpose.

What else pushed this pine cone study up another notch?

We have had sort of an on-going study of the female and male cones of the pines in our area.

We studied pine cones back in February of 2008 as part of the Winter Wednesday studies: Cones and a Woodpecker. We also studied pines as part of the Winter Series back in February 2010. This time though we are really trying to concentrate on the cones.

We extended our study of female and male cones.

Male cones with the pollen.

This is the photo that sort of started it all so long ago. We wondered if these were “baby pine cones”. Well, it turns out they are not and only after completing a study of what gymnosperms are in our biology study did things start to fall into place. There are male and female cones on the tree. Females are usually at the top and males at the bottom. The males have the pollen that is wind driven up to meet up with the female cones.  How about a simple video that even I can understand? Here you go!

Pine Cones on

Next we wondered why the female cones are sticky and then we guessed it had to do something with capturing the pollen…but that is whole other subject.

Squirrel 11 22 10
This guy wanted to be included in our pine cone study this week. He was so very happy that I put out some extra walnuts for him when I was filling the birdfeeders and he climbed up the tree to look in the living room window at us.

“Thanks a lot”, he said as he swished his big fluffy tail and then dropped to the ground and off to eat some more.

There were also some bird friends that made an appearance but I will save those for another post.

There is always something to learn about in our world and these challenges have helped us focus on things that we never dream of making into a complete study all on their own. I love it.

Of Mice and Snow

3 31 10 snow trees

Last night my boys were going down after dark to put our cats in their basement room for the night. They have to walk right past our bird feeder along the way and this night they saw some kind of creature inside the feeder eating.

They ran back up and had me go outside to see and by the time I got out there the creature was climbing up the supporting rope and up into the tree. I got just a glimpse and I actually saw two critters climbing up. The boys were sure it was something like a possum or rat but I didn’t think so from what I had seen.

We pulled out our mammal field guide and started paging through. What was the tail like? How was the head shaped? How big was it? What color was it? We went through all the pages and decided it had to be some kind of rodent.

I crept back to the door with the flashlight and quietly tiptoed out to the deck rail. I flipped on the switch and there in the feeder were the biggest mice I have ever seen. They looked straight at me a few seconds and then made a leap from the feeder to the tree, out onto a branch, and then hopped over to another tree and out of sight.

As long as they stay outdoors I can live with a few mice in my feeders.

3 31 10 tulips in the snow
This morning we woke up to snow on the ground and more coming down as daylight broke. I was so glad that I had gone out yesterday and cut a lot of my tulips and daffodils to bring inside. The ones left outdoors look so sad.

Our dog thinks this is perfect weather to be outdoors. It brings out the Labrador in her.

We are off to enjoy our very snowy day….I think hot cocoa is in order since this will more than likely be the last of our snow for the season.

Squirrel Study: Sad Story of Our Walnuts

Pile of Walnuts

We have a beautiful walnut tree in our backyard and it has always given us an abundance of nuts each autumn. The photo shown here is from a few years ago and shows part of our walnut harvest. Around this time of year, we are usually gathering oodles of nuts to dry and crack to eat and save for our baking.

Not this year.

Grey squirrels came and ate every last nut in our crop. Climbing into the tree, they would pick the nuts wrapped in their green outer coats, strip the casings off, and then proceed to crack the shells to get to the meat.

Piles and piles of shells and green casings dropped to the ground, littering the sidewalk and garden below. I thought surely they couldn’t eat them all, but they did.

I have mixed feelings about the whole situation. On one hand, I love having the furry little guys in my yard and away from my birdfeeders. On the other hand, I would have liked to have had a few nuts in my pantry for cookies and muffins and salads. This autumn will be known as the year with no nuts.

Our front yard also has a squirrel that visits quite frequently. It is a different variety of squirrel and he is FAST.
Squirrel in the tuliptree 2
(I shared this photo a few weeks ago during our tree study…we think it is a Fox Squirrel.)

He is busy eating the seeds from the tulip tree.

Look at those feet! No wonder they can climb and jump like they do!

He nibbles and then scurries off down the street, as if he has a regular route he takes to dine at various spots in the neighborhood.

Squirrel on the front wall 1
He is fun to watch as he bounds down the street and up onto the neighbor’s narrow fence top. My son, who does a lot of his schoolwork in the living room at the table by the window, calls my attention to our resident squirrel all the time. We are getting to know him quite well this year.

The other day as I was driving down a fairly busy street in town, a squirrel decided to run out in front of me. I know from experience that they usually dart out of the way at the last minute and I try not to get too excited. This one seemed to look me in the eye as he sat in my lane of traffic, a crazy game of chicken. Starting to move, he zigged and zagged a little in front of me and stood still again as I got closer. I slowed a bit and started coaching him to “Get out of the way!” At the last possible moment, he ran off to the side of the road and quickly up a tree. Why do they do that?

For the most part, we enjoy our neighborhood squirrels and find a great deal of entertainment value in this rodent. Our favorite squirrel actually walks the telephone line at a busy intersection in town. We see him probably once a week doing his tight-rope act, defying gravity and giving us something to be in awe about with this little one of God’s creation.

Here is our link to our previous squirrel study if you would like to read that one:

Watch this video to see another common squirrel in our area…the California Ground Squirrel. This video was taken last spring on a hike we took not too far from our home.
