%2011.jpg)
The broad-billed motmot (Electron platyrhynchum) is a fairly common Central and South American bird of the Momotidae family. They are nonmigratory, sedentary birds that are most frequently seen in singles or pairs. There exist six subspecies of the broad-billed motmot.
Its range encompasses the eastern side of Central America from Honduras to Panama, and it extends into many countries in north-western South America, including Colombia, Ecuador, Peru, Bolivia, and Brazil.
This bird resides in humid forests, warm lowlands and foothills, and is found at elevations below 3,000 ft (910 m).

Rosenberg's treefrog (Hypsiboas rosenbergi), also known as Rosenberg's gladiator frog or Rosenberg's gladiator treefrog, is a species of frog in the family of tree frogs (Hylidae) and genus of gladiator frogs (Boana) found in Costa Rica, Panama, Colombia, Trinidad and Tobago and north-western Ecuador. Its scientific name is a testimony to Mr. W. F. H. Rosenberg who collected the type series, and its common name refers to the aggressiveness of males of the species.

28-3-2017 CARARA NAT PARK, COSTA RICA - STRAWBERRY POISON DART FROG (Oophaga pumilio)
The strawberry poison frog, strawberry poison-dart frog or blue jeans poison frog (Oophaga pumilio, formerly Dendrobates pumilio) is a species of small poison dart frog found in Central America. It is common throughout its range, which extends from eastern central Nicaragua through Costa Rica and northwestern Panamá. The species is often found in humid lowlands and premontane forest, but large populations are also found in disturbed areas such as plantations. The strawberry poison frog is perhaps most famous for its widespread variation in coloration, comprising approximately 15–30 color morphs, most of which are presumed to be true-breeding. O. pumilio, while not the most poisonous of the dendrobatids, is the most toxic member of its genus.
Oophaga pumilio is diurnal and primarily terrestrial, and can often be found in leaf litter in both forested and disturbed areas. Studies have shown that the optimal habitat is determined by the male, considering the resource benefits and defense costs. Males tend to expend more energy defending smaller but higher quality areas. There has also been evidence that the better competitors and fighters are the males guarding smaller sites with higher female density. In most Anura the louder the vocalization when competing usually means they are larger in size and in better health. However, in the O. pumilio species researchers have determined that these frogs call out at a lower rate to limit their energetic expenditures. Females, on the other hand, simply distribute themselves according to tadpole rearing sites.
Though brightly colored and toxic, these frogs are relatively small, growing to approximately 17.5–22 mm (0.69–0.87 in) in standard length.

The keel-billed toucan (Ramphastos sulfuratus), also known as sulfur-breasted toucan, keel toucan, or rainbow-billed toucan, is a colorful Latin American member of the toucan family. It is the national bird of Belize. The species is found in tropical jungles from southern Mexico to Colombia. It is an omnivorous forest bird that feeds on fruits, seeds, insects, invertebrates, lizards, snakes, and small birds and their eggs.
28-3-2017 CARARA NAT PARK, COSTA RICA - GREEN AND BLACK POISON DART FROG (Dendrobates auratus)
The green-and-black poison dart frog (Dendrobates auratus), also known as the green-and-black poison arrow frog and green poison frog (among others), is a brightly-colored member of the order Anura native to southern Central America and Colombia. This species has also been introduced to Oahu, Hawaii in an effort to lower mosquito numbers. It is one of the most variably colored species of poison dart frogs, after D. tinctorius, Adelphobates galactonotus and some Oophaga species. From a conservation standpoint, it is considered to be of least concern by the International Union for Conservation of Nature. Within the reptile and amphibian hobby, D. auratus remains one of the most commonly kept, and easiest-to-breed, dart frogs in captivity, as well as in zoos.
The green-and-black poison dart frog is found in humid lowland and submontane forests at altitudes of 0–1,000 m (0–3,280 ft) in southeastern Nicaragua on the Atlantic slope, eastern Costa Rica on the Atlantic slope and in the southwest on the Pacific slope, widely in Panamá, and into far northwestern Colombia in the Chocó Department. An introduced population exists on Oahu, in Hawaii; the species was intentionally introduced there, in 1932, for mosquito control. Later on, it seems to have also become established on Maui.
