For the first page I worked out in the field, sketching plants, bees and birds. I also added watercolor to my sketches. The text (ink) was added later when I was back home. You can also see my small color chart at the lower right.
Here you can see my butterfly sketch (with colored pencils and watercolor added), and the small map I made after my hike through the forest. And the second page shows the quick bird webcam sketches - with very loose lines and a bit of color. I always make sure I add notes of the aspects I find interesting.
Nature journaling outside is always a lot of fun for me! I hope it is for you too!
