Hoatzin Opisthocomus hoazin Guyana's National Bird, locally called 'Canje Pheasant', with Canje being a river in Guyana. Some people call them 'Stinkbirds' because they smell bad (see digestive system)
The Hoatzin is a very peculiar bird. How peculiar - well, go read what Wikipedia has to say about it here. It has a digestive system different from other birds, to digest its diet of leaves. The young hoatzins have claws on their wrists to help them crawl back into trees, after they jump into the river to escape preditors, or bale out for other reasons - maybe just to take a little swim in the hot, humid afternoon. Perhaps our fearless leader, Richard Knapton, will weigh-in with his knowledge re this bird.
Whatever, it was an absolute joy to see these birds. They are wonderful.
