Red Eyed Tree Frogs

Red eyed tree frogs are vibrantly colored frogs that inhabit the rainforest canopies of Central and South America. Known for their neon green bodies, blue-striped legs, and large, bulging red eyes, these small frogs have captivated people across the world. Their adaptable toes, excellent climbing abilities, and unique defenses like flash coloration make them excellently equipped for life in the treetops.

While fascinating to observe and study, red eyed tree frogs are facing major threats in the wild. Habitat loss in their sensitive rainforest ecosystems poses the biggest risk to their populations. Raising awareness and supporting conservation initiatives are key to ensuring the survival of these charismatic frogs.

Red eyed tree frogs belong to the amphibian family Hylidae and are given their scientific name of Agalychnis callidryas. They are medium-sized frogs, growing to between 1.5 and 2.5 inches in length as adults.

These arboreal frogs spend most of their time dwelling in trees and plants within the rainforest canopy. This niche high up in the treetops provides the ideal habitat for the species to thrive. However, deforestation and fragmentation of their specialized ecosystem is having severe impacts on red-eyed tree frog populations.

Understanding the natural history, behavior, anatomy, and habitat requirements of red eyed tree frogs gives key insights into protecting these diminutive green frogs. Through conservation partnerships, habitat restoration, and responsible ecotourism, there is hope that red eyed tree frogs can continue clinging to rainforest leaves for generations to come.

Key Takeaways

  • Red-eyed tree frogs, known for their vibrant appearance, inhabit the rainforest canopies of Central and South America.
  • Threats like habitat loss, climate change, pollution, disease, and the pet trade endanger their survival.
  • Conservation efforts, including habitat preservation, disease control, and responsible pet trade practices, are crucial for their survival.

Red-Eyed Tree Frog Facts and Features

Red eyed tree frogs display several very distinctive features that make them easily identifiable. Their neon green upper body surfaces, vibrant red eyes, and unique adaptations like suction-cup toes make them a standout among frog species.

Physical Characteristics

The bright green dorsal surface helps provide camouflage amidst rainforest vegetation. However, red eyed tree frogs can rapidly change color from green to brown or grey to blend in better with their surroundings. The frogs also have blue and yellow stripes along their sides.

The red eyes are perhaps the most visually striking characteristic of the red-eyed tree frog. The bulging, vivid red eyes are thought to serve an anti-predator function through a defense called startle coloration. By suddenly exposing their bright red eyes, the frogs may momentarily shock or confuse predators.

Red eyed tree frogs have webbed feet with specialized toe pads that work like suction cups. These allow them to efficiently climb and grip onto leaves, branches, and other vegetation. The toe pads are highly adapted to life in the trees.

Some key physical features of red eyed tree frogs include:

  • Size: 1.5 – 2.5 inches in length
  • Weight: Up to 0.14 ounces
  • Color: Vibrant green with blue, yellow, and black markings
  • Eyes: Large, bulging red/orange eyes
  • Skin: Smooth, moist skin with light yellow underside
  • Legs: Slim, muscular legs optimized for jumping
  • Feet: Toes have expanded adhesive pads for climbing

Young frogs may be brown or grey in color until they mature into the familiar green adults. Females also tend to be slightly larger than males.

Habitat and Range

Red eyed tree frogs occupy a habitat niche in the canopy layer of tropical lowland rainforests, from sea level up to around 2000 feet in elevation. They require constant humidity and proximity to water sources like slow-moving streams or ponds.

During the day, the frogs find refuge tucked away in bromeliads, leaves, branches, and other vegetation high up in the trees. Here they can remain safely hidden from predators. At night, they emerge to hunt for insect prey on leaves and near water

Red eyed tree frogs inhabit tropical forests from southern Mexico through Central America, including:

  • Mexico: Southern Mexico, including the Yucatan Peninsula
  • Belize
  • Guatemala
  • Honduras
  • El Salvador
  • Nicaragua
  • Costa Rica
  • Panama
  • Colombia: Northern coastal regions

Within this range, intact rainforests with sufficient humidity and prey availability provide prime habitat. However, preferred habitat continues to decline.

Diet and Hunting

Red eyed tree frogs are carnivorous and insectivorous, feeding on live insect prey. They are nocturnal sit-and-wait predators. The frogs will stake out positions on leaves and remain very still, camouflaged against the vegetation.

Once an insect lands or crawls within striking distance, the frog’s long, sticky tongue rapidly shoots out to snag the prey. The tongue retracts back into the mouth equally quickly. Common prey items include:

  • Crickets
  • Grasshoppers
  • Flies
  • Mosquitoes
  • Beetles
  • Caterpillars
  • Moths
  • Other small insects

The frogs have also been documented consuming smaller frogs on occasion, including tree frogs and their own tadpoles. Their excellent vision, especially at night, helps them stealthily hunt down prey.

Red eyed tree frogs likely play an important role in controlling insect populations in their tropical ecosystem. In turn, they become food for predators higher on the food chain.

Behavior and Life Cycle

Red eyed tree frogs are mostly solitary and territorial creatures. They become more social during the breeding season, which coincides with rainy periods.

Breeding Season

Increased rainfall triggers breeding activity. Males congregate at suitable breeding ponds and vocalize to attract mates. Their duck-like calls sound like a rattling “click click click cluck-aaah”. Competing males may wrestle each other.

Once a pair mates, the female climbs over the surface of a large leaf and deposits a clutch of around 40 eggs. The male fertilizes the eggs as the female lays them. The adults then abandon the eggs, which will hatch after about 4 days. The eggs are typically green with dark spots.


After hatching, the tadpoles emerge and drop down from the leaves into the pond below. Here they grow over the next 6-10 weeks, feeding on algae. They develop small tails, eyes, mouthparts, and hind limbs.


Through metamorphosis, the tadpoles gradually transition into tiny versions of adult frogs, now known as froglets. The tail gets absorbed while the body transforms. After about 12 weeks, they emerge from the water and move onto land. The small frogs reach maturity after 8-10 months. Adults may live around 5 years in the wild.


Red eyed tree frogs are mainly nocturnal. During daylight hours, they find secure places to sleep, tucking into bromeliads or crevices in trees. Here they can safely sleep through the day, protected from predators. They emerge at night to hunt. While sleeping, they can change color to better match their daytime hiding spots.

Threats and Conservation

Red Eyed Tree Frogs Threats and Conservation
Red Eyed Tree Frogs Threats and Conservation

A combination of extensive habitat loss, climate change, pollution, disease, and collection for the pet trade have led to decreased red-eyed tree frog populations. However, focused conservation initiatives can help protect remaining frogs and restore degraded habitats.

Habitat Loss

The greatest threat facing red eyed tree frogs is loss of their tropical rainforest homes. Deforestation for logging, agriculture, development and other human activities has destroyed vast areas of former forest habitats. As their native environment dwindles, so do red-eyed tree frog numbers.

Remaining habitat becomes fragmented into smaller, isolated patches which support fewer frogs. Connecting these fragments via habitat corridors can help population flow and gene exchange continue. Outright stopping deforestation is a conservation priority.

Climate Change

A warming climate alters temperature averages and rainfall patterns from what red eyed tree frogs have adapted to in rainforest environments. Such changes can desync breeding cycles, impact vegetation, dry out habitats, and threaten survival. Minimizing greenhouse gas emissions can help curb the pace of climate change.

Pollution and Pesticides

Various chemicals from agricultural and industrial sources can pollute the environment of red eyed tree frogs. Pesticide exposure is highly toxic to amphibians, able to leach into waterways. Runoff tainted with chemicals creates challenges for sensitive frog species. Using environmentally friendly products and responsible waste disposal helps reduce pollution risks.


The infectious chytrid fungal disease poses a severe threat to amphibian populations globally, red eyed tree frogs included. Chytridiomycosis has caused precipitous frog die-offs in parts of Central America. Proper disinfection, monitoring frog health, and research into cures helps combat epidemics.

Pet Trade

High demand exists for brightly colored species like red eyed tree frogs in the amphibian pet trade. Most wild-caught animals die quickly from stress. Only captive bred specimens should be sold commerically or acquired as pets. Restricting trade in wild frogs helps combat unsustainable over-collection.

Conservation Actions

  • Protecting intact rainforest ecosystems
  • Creation of protected reserves with habitat suitable for red eyed tree frogs
  • Reforestation initiatives to replant native tree species
  • Corridor projects to connect fragmented forests
  • Regulation of unsustainable pet trade
  • Research into diseases impacting wild frogs
  • Breeding programs with zoos and aquariums
  • Ecotourism focused on highlighting rainforest biodiversity

Through comprehensive strategies including habitat preservation and restoration, disease control, regulated trade, and public education, the future outlook for red eyed tree frogs can be substantially improved.

Keeping Red Eyed Tree Frogs as Pets

The vibrant colors and unique appeal of red eyed tree frogs make them desirable pets for some amphibian enthusiasts. However, caring for these specialized rainforest animals takes precise attention to their habitat needs, nutrition, and responsible sourcing.


It is currently legal to keep red eyed tree frogs as pets in most U.S. states, but banned in Hawaii. Always check your local exotic pet regulations. Only acquire captive bred red eyed tree frogs from reputable breeders or dealers. Never purchase wild-caught animals.


Red eyed tree frogs require a simulated rainforest environment created in a tall, arboreal vivarium. Provide plenty of climbing branches, live or artificial plants, and hiding places like coco huts. The tank should maintain warm, humid conditions with good ventilation. Size requirements per frog are around 12” x 12” x 18”.

Include supple substrates like sphagnum moss or coconut fiber that retain moisture. Place the tank in a quiet location away from direct sunlight. Access to UVB lighting and a day/night cycle are important.

Humidity and Temperature

Use a hygrometer and thermometer to monitor humidity and temperature gradients. Humidity levels between 70-100% should be maintained. Install a misting system or manually mist the tank at least once daily.

Daytime temperatures of 75-85°F are ideal. A low wattage incandescent bulb can provide overhead heat. The tank can cool at night but should not drop below 65°F.

Food and Water

In captivity, red eyed tree frogs eat crickets, flies, mealworms, waxworms and other feeder insects. Dust food with mineral and vitamin supplements 2-3 times a week. Always wash hands before and after handling frogs or tank contents to prevent transferring diseases.

Provide clean, dechlorinated fresh water in small bowls, changed frequently. The water should be distilled or with added dechlorinating products. Some frogs may also drink off watered tank walls or leaves.


Red eyed tree frogs have delicate skin and do not tolerate frequent handling well. Limit handling to times for tank maintenance or transport. Always wash hands thoroughly first and support the frog gently but securely if picked up briefly. Ideal times are right after shedding or before feeding when skin secretions are lowest. Minimize handling to reduce stress on captive frogs.

With proper care in replicating their natural habitat, red eyed tree frogs can survive over 5 years in captivity, but 10-15 years is also possible. Confirm with your local laws before acquiring one of these iconic rainforest amphibians as a pet.
