Frog (Boophis tasymena)
Thanks to Daniel P Austin and Mark Scherz for the ID.
As dusk falls, the chorus calls. Short staccato bursts that fall silent with your approach. However, walking in-step with the pattering rain to mask my footsteps, I fell upon this beautiful frog calling. It retreated within its rolled leaf but not before leaving an indelible mark on my memory. Found during a night hike in Andasibe national park, Madagascar.
