Tweet of the Day is the voice of birds and our relationship with them, from around the world.

Sir David Attenborough presents the Vogelkop bowerbird of west New Guinea. The forest floor resembles a market stall with neat piles of brightly-coloured fruits and leaves placed carefully on a mossy lawn in front of a cave of thatched twigs. This is the work of the Vogelkop bowerbird. Native to New Guinea and Australia, this drab olive brown male, uses aesthetic tastes to bring vibrancy of colour into his life: and to woo his mate. His brightly coloured exhibits are graded for size and colour and any withered or faded items are quickly replaced. Satisfied with his work, he whistles, and growls to entice her to a private view. After mating the female departs to rear her single chick unaided, while the male returns to the task of tending his creation.
