For the first time, visitors to London Zoo can come nose-to-beak with some of the world's most beautiful - and rare - birds, including hummingbirds, kookaburras and toucans.

The Blackburn Pavilion, built in 1883 to house reptiles, has been modernised to showcase up to 200 rare and exotic birds, like this Peking Robin, in a naturalistic, free-flying arena.

The attraction, renovated at a cost of �2.5m, allows visitors to walk among tropical plants, pools and an indoor waterfall surrounded by the sounds of birdsong.

Among the collection is this blue-bellied roller, about to have its lunch...

...it's maggot on the menu for the large bird, with its brilliant blue wings - not an uncommon sight in African savannahs.

Less common though, is the Montserrat Oriole. The national bird of the island of Montserrat is classified as critically endangered.

This Amazilia hummingbird, capable of flying backwards, sideways and up and down, is part of the UK's only living collection of hummingbirds.

In recent years, London Zoo has been trying to bring down the bars to give visitors a closer look at its collections.
