Up until 1976, the species was occasionally recorded but it has not been observed since 1983. The main reason behind the disappearance of this fish is said to be the El Niño event which increased the temperature of the water surrounding the Galapagos Island. Carolina Parakeet was a native of North America. It was about 12 inches long, weighed about 10 ounces, and had a brilliant green body with a yellow and orange head.
