Birdwatchers went head-to-head at Slimbridge's Wildfowl and Wetlands Trust to see how many species they can spot.
The festival of birds took place as bird numbers peak in the Gloucestershire reserve as teams and individuals competed to record as many birds as possible.
On a good day at Slimbridge visitors can see up to 100 species of birds.
The less competitive got the chance to have a go at swan bill sketching, wild bird feeding and dog decoy demonstrations.
One Show star Mike Dilger, falcon expert Ed Drewitt, and Mya-Rose Craig, 12, who became the youngest person to see 3,500 species of bird, all attended the event.
James Lees, reserve warden, said: "The Bird Festival is a chance for us to really showcase what a fantastic day out Slimbridge is for wildlife lovers."
