The Costa Rica brook frog or red-eyed stream frog [2] (Duellmanohyla uranochroa) is a species of frog in the family Hylidae found in Costa Rica and Panama. Its natural habitats are tropical moist lowland forests, subtropical or tropical moist montane forests, and rivers between 70 and 1740 meters above sea level. [3] [4]
The skin of dorsum is leaf-green in color. The ventrum and neck are bright yellow. The ventral parts of the legs are dull yellow. A yellow-white stripe reaches from the lip down each side of the body to the groin. The iris is bright red with horizontal pupils. The female frog is larger than the male frog, with larger tympanums. [4]
This frog is nocturnal. It has been seen at night near mountain streams. During the day, they have been seen hiding in bromeliad plants. The frogs breed in May and June. The male frog's call sounds like "boop boop boop boop," but individual frogs and frogs in different geographic locations can sound slightly different. The female frog lays eggs in pools of water with silty bottoms. [4]
As of 2013, This species is classified as vulnerable by the IUCN. [1] Declines and local extinctions have been reported for populations (referred to as Hyla uranochroa) within the Monteverde region of Costa Rica's Cordillera de Tilaran, synchronous with the decline of 24 (from a total of 53) other amphibian species during 1990.

Duellmanohyla is a genus of frogs in the family Hylidae found in Oaxaca, Mexico, as well as Central America. These are small stream-breeding frogs have bright red, bronze or yellow irises. Their dorsa are uniform pale green, olive, red-brown or lichenose, with green or olive spots on a black background. Several species have pale upper labial and lateral stripes. Some fingers or toes have moderate webbing.
Atelopus varius, the Costa Rican variable harlequin toad or clown frog, is a small Neotropical true toad from the family Bufonidae. Once ranging from Costa Rica to Panama, A. varius is now listed as critically endangered and has been reduced to a single remnant population near Quepos, Costa Rica and has only relict populations in western Panama (IUCN). Recent variation in air temperature, precipitation, stream flow patterns, and the subsequent spread of a pathogenic chytrid fungus (Batrachochytrium dendrobatidis) linked to global climate change have been the leading cause of decline for A. varius. A. zeteki has been considered a subspecies of A. varius, but is now generally considered a separate species.
The evergreen toad is a species of toad in the family Bufonidae.
Cochranella euknemos, sometimes known as the San Jose Cochran frog, is a species of frog in the family Centrolenidae. It is found in central Costa Rica and south/eastward to Panama and to the western flank of the Cordillera Occidental in Colombia. Some Colombian records might apply to Cochranella mache.
Hyalinobatrachium colymbiphyllum, also called the bare-hearted glass frog, plantation glass frog and the cricket glass frog, is a species of frog in the family Centrolenidae that is found in moist forests, often near streams, in countries in Central America and South America. They are small, green frogs with many similarities to other glass frogs, however, they have the most transparent undersides of any glass frogs. Their transparent undersides make them ideal bio-indicators for how global warming and other threats are affecting the animals in the forests.
Hyalinobatrachium valerioi, sometimes known as the La Palma glass frog, is a species of frog in the family Centrolenidae. It is found in central Costa Rica and south to Panama and the Pacific lowlands and slopes of western Colombia and Ecuador; also in the Magdalena River Valley of Colombia.
The granular poison frog or granular poison arrow frog is a species of frog in the family Dendrobatidae, found in Costa Rica and Panama. Originally described as Dendrobates granuliferus, it was moved to Oophaga in 1994. Its natural habitats are tropical humid lowland forests; it is threatened by habitat loss.
The Chamula mountain brook frog is a species of frog in the family Hylidae endemic to Chiapas, Mexico. Its natural habitats are moist montane forests. It is threatened by habitat destruction and has been rated as "endangered" by the IUCN.
The Sierra Juarez brook frog is a species of frog in the family Hylidae endemic to Mexico. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, and rivers. It is threatened by habitat loss and possibly by chytridiomycosis, and the IUCN has assessed its conservation status as near threatened.
Savage's brook frog is a species of frog in the family Hylidae found in Costa Rica and Panama. Its natural habitats are subtropical or tropical moist lowland forests and rivers. It is threatened by habitat loss.
The rufous-eyed brook frog or rufous-eyed stream frog, is a species of frog in the family Hylidae. It is endemic to the mountains of Costa Rica. Its natural habitats are premontane wet forests and rainforests. Tadpoles are found in pools with standing water. Habitat loss is posing some threat to the species, although the overall population is stable.
The Honduran brook frog is a species of frog in the family Hylidae endemic to Honduras. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, and rivers. Scientists have seen it between 90 and 1400 m above sea level in Honduras in rainforests.
The Copan brook frog is a species of frog in the family Hylidae found in northeastern Guatemala and northwestern Honduras, specifically in the Sierra del Merendón, Sierra de Omoa, Sierra de Caral, and Sierra Espíritu Santo ranges. The colouring of this species is very distinctive and the specific name soralia comes from the resemblance of its markings to the vegetative structures on some crustose lichens.
The La Loma tree frog is a species of frog in the family Hylidae found in Costa Rica, Panama, and expected but not confirmed in Colombia. Its natural habitats are tropical moist lowland and montane forests, with breeding taking place in streams. It is threatened by habitat loss and chytridiomycosis.
Craugastor andi is a species of rain frog in the family Craugastoridae which has not been seen since 1990. It is found in the Caribbean drainage of Costa Rica in the mountains and hills of the Cordillera Central and the far northeastern Cordillera de Talamanca, and in extreme northwestern Panama. Frank and Ramus (1995) give it the vernacular name Atlantic robber frog. It is known locally in Spanish by the generic names, used for many species, of rana de hojarasca, ranita or sapito.
Craugastor taurus is a species of frog in the family Craugastoridae. It is found in the Golfo Dulce region of southern Costa Rica and adjacent western Panama. It is sometimes known as the Golfito robber frog.
Pristimantis altae, also known as mountain robber frog, is a species of rain frog in the family Strabomantidae with a bright coral-coloured groin. It is found in Costa Rica and Panama.
The horned marsupial frog, originally named Nototrema cornutum (Boulenger) after the first describer George Albert Boulenger in 1898), is a species of frog in the family Hemiphractidae. It is an arboreal species found in Colombia, Costa Rica, Ecuador and Panama. Its natural habitats are tropical moist lowland forests and montane cloud forests. It is threatened by habitat loss.
The Bale Mountains tree frog is a species of frogs in the family Brevicipitidae. It is the only species in the monotypic genus Balebreviceps and endemic to the Bale Mountains of Ethiopia. Its natural habitats are tree heath woodland near the timberline as well as partly cleared mixed forest further down. Despite its entire range being within the Bale Mountains National Park, it is threatened by habitat loss and deterioration (deforestation) caused by cattle grazing, firewood collection, fencing, and settlement development.
The golden toad is an extinct species of true toad that was once abundant in a small, high-altitude region of about 4 square kilometres (1.5 sq mi) in an area north of the city of Monteverde, Costa Rica. It was endemic to elfin cloud forest. Also called the Monte Verde toad, Alajuela toad and orange toad, it is commonly considered the "poster child" for the amphibian decline crisis. This toad was first described in 1966 by herpetologist Jay Savage. The last sighting of a single male golden toad was on 15 May 1989, and it has since been classified as extinct by the International Union for Conservation of Nature (IUCN).
