My trip to the Texas Gulf coast was a journey to primarily see two of the most endangered species in North America. The Whooping Crane and the Attwater Prairie Chicken. These two in particular have almost gone extinct and were on the International Union for Conservation of Nature (IUCN) Endangered Red list and are considered at the top of the list of the most endangered birds of North America. Whooping Cranes numbers dropped as low as 21 in the wild and only 2 captives.
