16. Atitlán Grebe
Also known as a POC, giant grebe, and enormous, pied-billed grebe, the Atitlán grebe is a type of water bird that has been extinct in North America since the early 1990s. This bird originated in Guatemala and began to decline about 25 years before it became entirely extinct. The Atitlán grebe reached lengths close to 24 inches and had large white or brown bills.
After largemouth and smallmouth bass were introduced to Lake Atitlán, the Atitlán grebe population began to decline. The fish not only ate their food source of crabs and fish, but they also killed Atitlan grebe chicks. The community began to increase in the 1970s, but problems with the lake bed led to it becoming extinct.
