The year's most spectacular bird snaps

The year's most spectacular bird photos including a kingfisher getting ready to devour its dinner have been revealed in their full glory. 

This year, Alejandro Prieto Rojas was named Bird Photographer of the Year for his memorable image of flamingos feeding their offspring in Mexico. 

Head competition judge Chris Packham said: 'As President of the British Trust for Ornithology I am proud to support Bird Photographer of the Year, a competition that will push bird photographers to new limits. We see lots of technically accomplished images and "nice" portraits of attractive species. But what we are looking for as judges are those images which have an instant and enduring "wow" factor. 

'To have been gifted with so many of these "wow" photos in the first two years of this competition is extraordinary, because photographing birds is enormously challenging. I am excited about seeing what this year brings and being involved again in choosing the best of the best.' 

The winning images are published in a book available for purchase from the British Trust for Ornithology and will be part of a traveling exhibition around the UK.

She said: 'This common species of duck's most identifiable feature is the iridescent speculum feathers which are often only visible during preening or flight. I took this photo at a small lake. The still waters and the dark foliage of the background resulted in an opportunity to highlight the gorgeous feathers. I exaggerated the effect in Adobe Lightroom, but otherwise have not altered the original photo'

I was trying to capture the moment when the net is fired and is still in the air above the camera. As we were waiting to fire the net this fox walked right at the front of the camera scaring all birds into the air -but at least I took this great image'

Scavengers: Marabou Storks were photographed by Daniel Rosengren,frmo Sweden. He said: 'Marabou Storks are scavengers, but they are not that good at ripping big pieces of meat off a carcass. Instead, they rely on other scavengers like hyenas or vultures to do that, so they can take the easy pickings from the ground. This photo was taken by placing the camera with a wide angle lens near the zebra carcass and trigger it with a remote from a distance.' The photo was taken in Tanzania
