Scientists researching bird populations have found that some birds travel surprisingly long distances.
The British Trust for Ornithology, who study bird habits and populations, asked volunteers to help them find out more about our feathered friends.
A million birds had numbered rings fitted so that they could be traced and identified as they flew across the world.
The longest flight recorded was from a seabird called a 'Manx shearwater' which was recorded flying 7,564 from Scotland to Argentina

Manx shearwaters aren't the only long distance flyers.
An Arctic skua, flew from Scotland to Brazil, which was 6,845 miles.
And a swallow flew all the way from Britain to South Africa!

Not only did the rings mean that the trust could see how far birds were travelling.
Researchers were able to find out how well different types of birds are breeding and how big their populations are.
They were also able to find out how long these birds lived for.

A Scottish fulmar bird that was ringed was found to be at least 41 years, 11 months and 17 days old.
The longest-living wild bird in Britain was found in 2008 and it was a 50-year-old Manx shearwater, from Bardsey Island in Wales.
