The most recognizable endemic species and a symbol of Puerto Rican pride is the "coquí", a small frog easily identified by the sound of its call, from which it gets its name. Most "coquí" species (13 of 17) live in the El Yunque National Forest, a tropical rainforest in the northeast of the island previously known as the Caribbean National Forest. El Yunque is home to more than 240 plants, 26 of which are endemic to the island. It is also home to 50 bird species, including the critically endangered Puerto Rican amazon.
