So the rains of late have brought the frogs to life somewhat and we're now up to 4 in the house (2 in the bath, 1 in a shower and this one in the kitchen). What made our latest visitor more interesting was that I think he's a different species.
I'm fairly sure this is Eleutherodactylus coqui aka the Bo-peep frog because of its call.
It might be something else, I'm waiting on more expert id's. By way of scale he's next to a american quarter dollar here.
