Bird migration is truly one of the most extraordinary phenomenona in nature. October is a time of travel for countless millions of wild birds - right across the Northern hemisphere, vast numbers of them, belonging to hundreds of different species, are on the move, in search of warmer climes and a reliable source of food.

The island of Ireland finds itself in a unique position when it comes to bird migration. Situated at the very edge of Europe and at the intesection of several intercontinental migratory flyways, it receives vast numbers of both summer and winter migrants. 

It is the first port of salvation for weary trans-Atlantic voyagers, a warm holiday destination for Arctic nesters eager to escape the polar winter, and a key staging post for several species that are en route to Africa.

To learn more, Derek went to visit Anthony at the North Bull Island in Dublin, along with ornithologist and zoologist Dr. Richard Collins, Niall Hatch (Development Officer with BirdWatch Ireland) and Eric Dempsey (author, guide and founder of
