Bird Talk
The Language of Birds is a section of the British Library sound archive where you can find out that 'There are only two species of bird that use sound to convey to man the unique message: "Follow me and I'll lead you to a bees' nest" ' and listen to them doing it (Windows Media Player required). The cunning black-throated honeyguide flies to the nearest village, makes a sound like a beehive, and lures a villager to come and open up the hive for it. Then they divide the spoils between them. A rare example of man and bird working in total harmony.
You can also listen to Sparkie Williams, the 'most famous British budgerigar', trained by Mrs. Mattie Williams of Newcastle-upon-Tyne, who had a six-year working life as a character actor (two accents: "Geordie" and "refined"). Here he is reciting "Jack and Jill' in a voice which I would guess is the refined version: sounds a bit like a middle-aged woman from Newcastle playing a polite Dalek.
