Almost the entire world's population of around 30,000 winters along the coast of Ireland.
Light-bellied brent geese have one of the longest migrations. They travel a staggering 2,900 miles from Ireland via Iceland and Greenland, including an incredible flight up and over the 1.5 mile high ice cap before continuing to their summer breeding grounds in arctic Canada.

WWT has teamed up with BBC Radio 4's World on the Move in a research first. This year, we are following three individual Greenland white-fronted geese, three Brent geese and three Barnacle geese as they make their epic migrations and compare how much fuel they need to complete them.
Which one will get their first? Will they all make it? Which one will be Top Goose?
