The main frog species I was hoping to see while in Andasibe, and in fact Madagascar, was from the family 'boophis'; in particular the Green Bright-Eyed Frog (boophis viridis). They're also known as tree frogs which encompass many different frog species, but are characterised by, obviously, their arboreal nature spending their time in trees. They have the ability to change colour from mustard yellow, reddish brown and vibrant green. Also, their inner and outer irises are blue.
I couldn't believe my luck when we came across a few of these tiny little frogs. They only reach around 3cm in size, so finding them was a challenge despite their vocals. They're surprisingly loud for their size, and I was constantly checking the trees and plants lining the road we were walking along desperate to find one as they teased with their calls, seemingly right in front of you. As I scanned the vegetation with my torch a small yellow object in the corner of my eye caught my attention. It turned out to be the first of 3 Green Bright-Eyed Frogs we saw that night. Barry saw it too and was elated at finding one. After all, we were searching for a frog that is easily seen in the wet season or after rain, but we were searching in the height of the dry season just before the wet season began.
