California Black Oak Tree – Our Autumn Nature Study

We have spent quite a number of our outdooor hours observing and learning about oaks. We are blessed with many different kinds of oaks right in our own yard so they are constantly a backdrop for many of our studies.  Here is a link to one of our entries that shows the variety we have: Oak Tree Study.

So what did we do for our Outdoor Hour Challenge on oak trees?

  • A little comparing – leave size and shape
  • Looking for acorns – found very few
  • Talked about how the different tree silhouettes in our yard – oaks are the prettiest

We settled on the California Black Oak for our nature journals, with its large lobed, bristle tipped leaves.

Resource to print: USDA Plant Guide

“The California Black Oak is strikingly unlike all other deciduous Oaks in the Golden State, for its broad thin leaves are jaggedly lobed, with the veins running out beyond the leaf margins as fine bristles.”
A Natural History of Western Trees.


We have noticed the woodpeckers that enjoy the tall branches, the Scrub jays that frequent the crown, and we are even thinking this is the tree that the bats use for shelter…not sure. It is a truly abundant food source for much of our local wildlife, including bears.

“…it has one admiring friend, the California woodpecker, who finds its acorns, bitter to our palates, exactly to his taste….This handsome redhead devours what he can hold of acorns, and lays up great stores of them, like a squirrel.”

There is always something to learn and to make note of as we revisit even a common tree to our area.


We are looking forward to observing:

  • The yellow leaves of autumn and then seeing the bare branches.
  • The dropping of acorns.
  • Finding a California Black Oak with acorn holes.
  • In the spring, pink or crimson of the new foliage.

Another successful oak tree study….thanks to our ability to see beyond the ordinary.

Outdoor Hour Challenge: Weather- Find Out For Yourself

Autumn Sky and Trees 1
Late Autumn Sky

“The scientific method of study is: Do not take things for granted, but find out for yourself. This method trains pupils to think for themselves. Too much talking by the teacher allows the pupils’ minds to lie idle and passive. Exercise strengthens them.”
Nature Study and Children

As you can tell if you are a regular reader of my blog, I love to quote old nature study books. These books are full of gems that still sparkle today with wisdom and practical advice. Timeless advice like you see above will help you be a better nature study guide.

Many of us are winding down our academics for the term and this week’s challenge is a great way to transition to the winter break. Weather observations are an easy to do while on a family walk or even from a window. Don’t overlook the power of a simple challenge. Remember the quote above.

Suggestions for this week’s challenge, pick one or do all five!
1. Take a walk and observe the weather. Informal nature study done while spending time together as a family is often the most meaningful. Get outside for a quick walk when you have a few minutes to spare.
2. Keep track of temperature for three days in a row. Record it in your nature journal to compare with future months. You can print a blank calendar page from Hearts and Trees.
3. Observe clouds over the course of a week. Advanced Study: Cloud Chart pdf  and for everyone: Clouds That Look Like Animals and Cloud Types.
4. Complete a seasonal weather notebook page.
5. Finish the grid suggestions from the November Newsletter.

Maple Study – Leaves Instead of Seeds

Apple Hill with Barn
Autumn Scene – Sierra Nevada Foothills

Our last study for the Autumn series (More Nature Study with the OHC) was one that took us up the mountain to see maples brilliantly colored against the autumn sky. The Bigleaf maples are ablaze with color right now and so easy to spot since they grow in and among the evergreens of the Sierra Nevada. Our field guide says that Bigleaf maples grow at an elevation of 2,000 – 5,000 feet so we live right at the lower edge of where they naturally occur.

Maple Trees
Perfect spot to stop and observe some Bigleaf Maples

We stopped alongside the roadway to gather a few leaves and take some images. When I opened the car door…Mmmmmm…it smelled like fall. I hope I don’t ever stop remembering to slow down enough to drink in the fragrance of autumn leaves, damp and woodsy.

Maple leaf
Lobed leaves, turning yellow-green

Now to the part that I have to be humble about. When I wrote the Maple Seed Challenge months ago I thought that this would be the time to gather seeds. Turns out after some direct observation and some reading in my tree book….that this may not be the right time for maple keys so now that we know where to find our little grove of maples, we will revisit it in the winter to see if can see any changes.

We decided that we might as well observe and learn more about the leaves of the Bigleaf maple.

Measuring the Maple Leaf
We brought one really big leaf home and measured it…a little less than twelve inches across. Our field guide says that the leaves should be 16-14 inches in length including the stalk so that is in line with what we found. Mr. B decided to start the advanced notebook page with the field guide information but wait on sketching the maple keys until we gather some at a later date.

On another big leaf note….

Catalpa Tree Leaf
How about this gigantic catalpa tree leaf that we found at my mom’s house last weekend? Isn’t it glorious? Amanda took a quick photo of me holding the leaf and I thought you  might get a kick out of seeing it, especially after seeing the maple leaf and thinking THAT was big. My little three year old grand-niece said, “What is that?” I told a it was a really big leaf and she laughed. I miss having little ones around who have lots of questions and everything is new and interesting.

Sigh, that finishes up the autumn challenges for now. This season of nature study went by entirely too fast!

OHC More Nature Study #10 Maple Seeds and Update for Nov/Dec OHC

Outdoor Hour Challenge Maple Tree and seeds @handbookofnaturestudy

OHC More Nature Study #10
Maple Seeds and Maple Tree

Inside Preparation Work:

  • Read in the Handbook of Nature Study pages 628-632 (Lesson 174). This is the section on the sugar maple. Pay special attention to the “Fall Work” section, especially #2 which describes the “key” and how to observe it. There is also a previous OHC for the Maple Tree that you may wish to look up and read for ideas to include in this challenge.
  • Other Maples to Investigate: Bigleaf Maple, Silver Maple, more listed on USDA. If you have a tree field guide, page through the maple tree section and get an idea of what kind of maples you have in your local area.
  • You will want to discuss with your child any winged seeds you are familiar with. We often call these winged seeds “helicopter seeds”. Another name for the winged seeds are samaras.

Outdoor Hour Time:

  • For this challenge, spend some of your Outdoor Hour time looking for maple trees and maple seeds. Gather a few of the winged seeds to observe and investigate. Maple trees in the autumn have beautifully colored leaves and should help you in finding one to study.
  • Have some fun with your maple seeds. Release them and measure the distance they travel and how long they stay afloat.
  • If you don’t have a maple tree or seeds to observe, see if you can find another tree observe that has seeds (oaks/acorns, conifer/cones, sweet gum/sticker balls, etc). Collect a few to bring indoors to observe with a magnifying lens.

Supar maple coloring page
Follow-Up Activity:

  • You may wish to talk about other seeds you have observed that fly or float in the air. How about dandelions, milkweed, and elm seeds as well as the maple? If you found maple seeds, compare them with other seeds you know about.
  • Allow time to make a journal entry, complete a notebook page, and/or finish a coloring page. Make sure to sketch the key with the seed and wing labeled. If you observed a tree other than the maple, you can complete the Seasonal Tree Study notebook page if you wish.
  • Plant a maple seed where you can watch it grow.
  • Read about why and how leaves change color in the autumn: A Tree’s True Color.
  • Advanced Follow-Up: Use a field guide to learn more about your maple. You can use this online tree field guide. Complete a notebook page for your nature journal (ebook users).
  • Advanced Follow-Up: Find other autumn seeds and make some observations. Suggested seeds: acorns, seeds from a cone, sticker balls, etc. Sort your seeds: Round/Not Round, Float/Not Float, Fly/Not Fly, Seeds That Lie Flat/Seeds That Do Not Lie Flat, and by Size.

Our Fall Leaf Study – A Lesson in Teen Nature Study

Orange Leaves in My Nature Journal
Pressed leaves going into my nature journal (See the November Newsletter for instructions.)

We are finally starting to see some fall colors all over our neighborhood. With our autumn color words in mind, we try to challenge each other to find just the right color words as we drive around town…noticing the crimson, the indigo, the mahogany, and the bronze of the leaves. (Download your own Advanced Fall Color Activity from Hearts and Trees.)

As part of the Leaf Close-Up challenge, Mr. B was happy to come along to gather fall leaves but not too excited about doing the follow-up for this one. His teen attitude was that he knew all there was to know about leaves. I let it go for that day since we had enjoyed spending time together outside and I did not want to spoil the mood.

11 2011 Red Yellow Green Leaves

I waited until another day to try the advanced study work suggested in the challenge which was to make our own slides using the leaves we gathered, looking closer at them using a microscope. As much as I want my teen to continue his nature study, I know that pushing him too hard takes the joy out of it and that is the opposite of my aim in continuing nature study through high school.

It can wait.

11 2011 Leaves on the tree
Fall leaves with larvae.

So, even though a leaf study was not a great fit for Mr. B, I tried to finish the challenge myself this week, hoping he would join me. Well, right off the bat I needed his help with the microscope. It did not seem to be working so he took a look at it for me but he could not get it going either. That ended another day of trying to get this challenge done.

Then on Friday, Mr. A (my older son who has graduated from high school) was home and I asked him if he wanted to finish up the challenge with me. He actually was eager to participate. He brought his own leaves in and got to work. The image below is a glimpse at his notebook page from the More Nature Study ebook. He ended up using the hand lens instead to view the leaves up close.

Leaf up close Notebook Page
Advanced Study notebook page from More Nature Study ebook

This challenge led to a light bulb moment for me.

  • Mr. B was not interested in this particular challenge but we did enjoy our time together outdoors viewing the trees and leaves. For Mr. B, that was enough.
  • Mr. A *was* interested in taking a closer look with me at the fall leaves even though he has graduated from homeschool.

Lesson? I am succeeding in keeping my teens interested in nature study. As always, I need to learn to be flexible and allow for personal taste and styles of learning.

For more on that topic make sure to read the article in the November edition of my Outdoor Hour Challenge Newsletter from Ellen Crandall (available to all subscribers to my blog-see the sidebar to sign up). She has a few teens in her home that she is encouraging nature study with each month.

Our October Bird List and Sparrow Study Using the Handbook of Nature Study

As part of our House Sparrow study, we kept track of the tally of birds who have visited our feeders. We have a regular contingency of sparrows but this month the numbers have greatly increased. We saw two kinds of sparrows this month.

Using the More Nature Study Challenge for House sparrows, we did some research to see what other kinds of sparrows there are in our neighborhood. We did this by going to the Great Backyard Bird Count website, clicking the Explore the Results button at the top, and then entering our town name. This brings up all the statistics from the latest Bird Count – Bird species, number of birds, number of people reporting observations of a particular bird. I found this very helpful. According to the lists, in February there are lark sparrows, song sparrows, house sparrows, and golden-crowned sparrows seen in our town.

House Sparrow Notebook Page
Advanced follow-up notebook page from the More Nature Study with the OHC ebook.

We decided to look those particular sparrows up in our field guide and note their field marks just in case we happen to see these three other species sometime in our area. The trouble is that the females all look very similar. We found the What’s That Sparrow? page on the Cornell website very helpful.

Here is the list of other October birds…we were not as diligent this month at recording our birds but I am going to try to keep it as a daily task for Mr. B the whole month of November. 🙂

October 2011
California towhee
Spotted towhee – first ones we have seen since spring at our feeder
White-crowned sparrows – increase in numbers
House sparrows – increase in numbers
White-breasted nuthatch
Oak titmouse
House finches
Turkey vultures – soaring overhead
Mourning doves
Western scrub jays
Lesser goldfinches
American robin
American crow
Anna’s hummingbirds – still coming in numbers to the feeders

Heard our Great horned owl and California quail
Along the road we saw Wild turkeys, Brewer’s blackbirds, pigeons, Canada geese, and a Snowy egret.
There were also several Red-tail hawks and a Cooper’s hawk on a drive to town.

Do any of you participate in the Project FeederWatch Program? It starts the second Saturday in November and I think our family is going to join in this year since we have made a habit of keeping track of our feeder birds anyway. Do you want to join up too? Click over and read all about it! Or watch a video.

We also are submitting this post to Heather’s Tweet and See link-up.

OHC More Nature Study #7 House Sparrow

Outdoor Hour Challenge House Sparrow @handbookofnaturestudy

More Nature Study #7
House Sparrow (English Sparrow in the Handbook of Nature Study)


Inside Preparation Work:
1. Read pages 83-85 in the Handbook of Nature Study (Lesson 20 English Sparrow). Highlight some points you can share about the house sparrow with your children.
2. If you have a bird field guide, use the index to look up the House sparrow and any other sparrows you may have in your area.
3. Let your children see an image of the House sparrow and have them describe what they see. (You may use the information in the Additional Links section below.)
4. Younger Children: Read the Burgess Bird Book chapter on the English(House) Sparrow online. Listen to an MP3 recording of the chapter.

birdhouse
Outdoor Hour Time:
1. Seize the opportunity to observe a House sparrow during your week. This may need to be done from a window at first but outdoors is always better if you can keep still and quiet as you observe. If you have a pair of binoculars, take them along with you so you can view the sparrow’s features. Try to observe their color, size, beak, tail shape, and behavior. Look for House sparrows in your yard in bushes or hedges, in parks, or even around buildings in urban areas.
2. If you don’t have a House sparrow to observe, choose another bird and have your child describe its features. (It is always good to compare size, shape, beak, and tail.)

cherry tree

Follow-Up Activity:
1. After your Outdoor Hour time, take a few minutes to follow-up your bird observation time. Pull out your field guide and learn a little bit more about any birds you were able to view.
2. Allow the opportunity for a nature journal entry, a notebook page, or time to color the accompanying coloring page.
3. Advanced follow-up: Compare the House sparrow with another sparrow in your neighborhood. You can use the accompanying notebook page for your notes (ebook users only).
4. Advanced follow-up: Watch for the House sparrow in all four seasons. Keep a record of what months you see them in your yard or neighborhood.

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!
