The early days of the BBC and the rainforest

I love this picture. It's Charles Lagus, David Attenborough's friend and colleague, filming in 1955 for 'Zoo Quest to Guiana', one of the first forays the BBC made into natural history broadcasting. I've devoured 'Life on Air' several times... ;) But I haven't yet been able to watch 'Zoo Quest to Guiana'! The various other 'Zoo Quests to...' have all be put online by the BBC, but Guiana remains mysteriously absent. One day I'll get my hands on it. And yes I know that's (British) Guyana, not French Guiana, but it's such a great picture of the tropics that it makes me want to drop everything and be deep in the forest....
