Masked Tree Frogs are a common sight in Drake Bay, and very often they are heard before they are seen. Their raucous call fills the air throughout the rainy season and during the dry season rains. They are good sized tree frogs and adults measure between 40 to 78 millimeters.
Their common name comes from the black patch that starts at the tip of the snout and continues through the eye and the eardrum, along the frog’s face. This black mask will enhance the frog’s camouflage by hiding the shape of the eye, which is what many predators will use to detect their prey. They can change their color and you may find frogs with coloration ranging from light tan to olive green.
