Red Eyed Tree Frogs

If you want to learn about Red Eyed Tree Frogs, this page contains lots of useful information about its habitat and lifestyle, as well as how it is affected by changes to the rainforests.

Red eyed tree frog

The Red-eyed Tree Frog (Agalychnis callidryas) is an arboreal hylid native to Neotropical rainforests in Central America. It is a small-sized tree frog, reaching lengths of about 5 - 7 centimeters (3 inches). Its dorsal surface is green of varying shades, and its ventral surface is white. The sides of the frog are purple or blue, with vertical white stripes and orange toes. Young frogs are typically brown in color and turn greener as they mature, although adult frogs can change their color depending on mood and environment.

Both females and males have bulging orangy red eyes with vertically narrowed pupils, resembling the eyes of domestic cats. Red-eyed tree frogs have soft, fragile skin on their belly, and the skin on their back is thicker and rougher. Bright markings along the sides and limbs reduces predation. Most animals that prey on A. callidryas (some bats, snakes, and birds) often rely on their vision. When the frog moves to avoid the predator the bright colorations flash into view (hence their name, flash colors) and throw off the predator. This is achieved by leaving a ghost image in the visual field of where the frog was originally. This confuses the predator and gives the frog time to hide. These flash colors may also deceive predators by making the frog appear poisonous.

Red-eyed tree frogs are not poisonous and rely on camouflage to protect them. During the day, they remain motionless, cover their blue sides with their back legs, tuck their bright feet under their belly, and shut their red eyes. Thus, they appear almost completely green, and well hidden among the foliage. Their eyes seem to glow in the dark.

Red-eyed tree frogs are mainly carnivores. They prefer crickets, flies, grasshoppers and moths. Sometimes, they will eat smaller frogs. For froglets, fruit flies and pinhead crickets are the meals of choice.

The following have been listed as threats to the survival of the species:
Habitat Loss/Degradation - Agriculture - Crops - Shifting Agriculture
Habitat Loss/Degradation - Agriculture - Crops - Small-holder farming
Habitat Loss/Degradation - Agriculture - Crops - Agro-industry farming
Habitat Loss/Degradation - Agriculture - Livestock - Small-holder
Habitat Loss/Degradation - Agriculture - Livestock - Agro-industry
Habitat Loss/Degradation - Extraction - Wood - Clear-cutting
Habitat Loss/Degradation - Infrastructure development - Human settlement
Pollution (affecting habitat and/or species) - Land pollution - Agriculture
Pollution (affecting habitat and/or species) - Water pollution - Agriculture

Red-eyed tree frogs are closely related to chorus frogs, which have the same body style and many of the same habits, though chorus frogs are more vocal.

Distribution and Habitat
Red-eyed tree frogs inhabit rainforests from southern Mexico, through Central America, to Northern Colombia. They are often found near rivers or ponds.

We are supporting the World Land Trust (WLT) - a conservation charity involved in numerous projects worldwide. Particularly relevant to this site is their work in helping to purchase rainforest land to protect and preserve it.
You can Help to Buy Rainforest and Save it by donating to the WLT to save some of this land through a personal contribution or buying as a gift.

If you have any photos, stories or drawings of toco toucans, other animals or anything else to do with the rainforest environment that you would like to see shown on the site, please feel free to send them in. We always welcome contributions or constructive comments.
