Of all the Islands on the Edge, the Outer Hebrides are the most exposed the full power of the Atlantic. Despite this, the wildlife here is the most spectacular in Europe.

On the outlying islands, seabirds rush to feed up their chicks while avoiding the murderous intentions of 'bonxies' - predatory skuas with a taste for young puffins.

On the low-lying Uists, acres of beautiful meadows burst into flower as Summer finally arrives.

But this is a year of drought and Atlantic salmon find themselves trapped in the sea pools and unable to move into the river systems. Yet again the creatures of the Hebrides must find ways to survive the extremes of these Islands on the Edge.
