The Grey Foam Nest Tree Frog is a fascinating little critter. The female whips up a foam nest with her eggs, usually on the branch of a tree or bush hanging over water. The males then pile on, depositing their contribution into the nest. It's a hell of a thing to see. A lot of action in this little clip, which is essentially a BLO (borderline orgy). Mother nature never ceases to astonish. From Hwange NP in Zimbabwe. | Billy Dodson
