Field Notes
I see many trees broken down, I also see fluff from leaves and also a huge frog. I hear chirping birds and leaves blowing in the wind. I smell the freshness of the forest. A rock that we could not see when the vernal pool was filled up we can know see. Most of the plants are green know!

Supporting Evidence

Most people who deal with Bull and Green Frogs know that the two often get confused. On a Green Frog the underside will be a cream and white color. Bull Frogs almost have the same thing, but they have darker areas and large specks. The easiest way to tell them apart are their glandular folds. This is the biggest visual difference between the two. On the Green Frog the fold will start on the edge of it's eye and go in a straight line down the back. On the Bull Frog it starts in the same spot as the Green Frog, but has an interesting fold that wraps around the tympanum.

I love your sketch. Did you find a salamander?

It seems like your class has learned a ton from all the great species expert comments. :)

Great work!


Wonderful description of how you determined you found a bullfrog!
