The hoatzin is also known as the Canje pheasant, but has also been called the punk-rock bird, and you can see why. It sports a colorful array of feathers on top of its head that resemble a mohawk of sorts. They live in the mangroves of South America and have very many unique characteristics that set them apart from other bird species. Firstly, their chicks are born with claws on their wing digits, though it’s unknown what they’re used for. Secondly, the bird’s unique digestive system creates a manure-like smell, earning this bird another nickname of the stinkbird.
