This week Steve Leonard infiltrates the most heavily scrutinised patch of rainforest on earth. In the ultimate jungle stake-out, undercover cameras reveal the secret lives of jungle cats; multi-flash photography exposes how bats catch fish; and scientists use miniature bugs to decipher a secret bee language of ‘buzz words'. Steve even scales one of the seven forty metre high radio towers that track ocelots, agoutis and sloths 24/7.
