Peter Baye has several large tubs that he uses for a wetland nursery. Sierran Treefrogs moved right in.  During the wild storms several weeks ago, the males became agitated and started vocalizing, sending out their mating call.

You can see the males' vocal sacs are fully extended.

The next morning there were eggs at the bottom of these tubs. Love was definitely in the air!

Thanks to Peter for allowing me to share his photos with  you here.
