Monte Azul is home to a number of highly visible animals such as a local family of capuchin monkeys or the Aracari, as well as a number of resident and transitory animals. It is also a home to a large number of White Crested Coquette hummingbirds, which are highly sought after by birdwatchers from around the world. Monte Azul is a valuable biological corridor that connects our property directly to the Chirripó and La Amistad Park, which straddles both Costa Rica and Panama. An astounding 30% of the species are endemic to the region:

• 13 out of the 215 species of mammals
• 15-30 of the 600 species of birds
• 20 out of the 250 species of reptiles and amphibians
• one out of the 115 species of fish are endemic to the reserve.

Among the mammals in the Talamanca Mountains are the Central American squirrel monkey (Saimiri oerstedii), blackhanded spider monkey (Ateles geoffroyi), and giant anteater (Myrmecophaga tridactyla). There are abundant signs of lowland tapir (Tapirus terrestris) in Costa Rica, in Cerros Utyum, Kamuk and Fabrega near the Panamanian border. There are also the Central American tapir (Tapirus bairdii) and red brocket deer (Mazama Americana).
