Which species is a "mountain chicken"?

The answer is frog. The mountain chicken is a species of frog that is found in the Caribbean islands of Dominica and Montserrat. Despite its name, it is not actually a chicken but rather a frog with a large body size, reaching up to 8 inches long. It is known for its vibrant coloration and powerful hind legs, which allow it to leap great distances. Sadly, the mountain chicken population has declined rapidly due to habitat loss, volcanic activity, and a deadly fungal disease, making it critically endangered.
