An Eastern Gray Tree Frog

This is a photo I took in Autumn when I was at my sister-in-laws house. I've always heard the frogs calling sounds but had never seen one until that day. Turns out it is an Eastern Gray Tree Frog. It was on the outside wall of her red shed. The Eastern Gray Tree Frog can be found mainly in the eastern United States and southeastern Canada. Evidently, they can change their coloring according to the weather. They can appear as green, gray and brown. This frog was about two inches long and mostly a light gray in color. They like to eat small insects including spiders and mites. I was surprised to see it during the day and on a shed but possibly it was looking for food or was taking in some warmth from the sun hitting the shed. Maybe it thought it was a tree as the shed is made of wood. I didn't touch it as I didn't want to disturb it and it turns out that it can produce a toxic skin secretion which can cause extreme discomfort to the eyes, lips, mucus lining of the nose, open cuts and abrasions (cited from https://srelherp.uga.edu/anurans/hylchr.htm). Glad I listened to that little voice in my head that said just take the photo and leave it alone!!
