I decided to share some links to pages that I use to help us draw in our nature journal. Several are links to coloring pages but I like their black line drawings that simplify an object so we can learn to draw them on our own in our journals. Make sure to check out all the links even if they are from a state or habitat other than one where you currently live. Many times there are animals, plants, and birds that you will have in your location too. I don't necessarily print the coloring book pages out and color them. We will use them as a guide to draw our own sketches of things we see in our Green Hour or for our nature journal.
Celebrating Wildflowers from the US Forest Service
These coloring pages are in PDF format so once you bring up the page, you can print out just the page you want and there is no need to print every page out on your printer.
Feeder Birds Coloring Book from Cornell
These are not only coloring pages but could actually be used as notebooking pages for your nature journal. I print out the table of contents to keep in my notebook as a reference. This way I know what birds are included in the coloring book.
