Walking around Hirta, the island is full of new life at the moment. Young birds are preparing to leave their parental nests but in doing so place themselves at great risk from predators. Cryptic plumage camouflages the youngsters against their background.
Eider duckilngs, brown, swimming amongst the kelp are hard to spot.
Resting out on the old concrete slipway they are more visible and watched over by Mum.
Lesser Black backed Gull and chick can be clearly seen against the grass, but the larger grey chick to the right is much harder to spot resting on a rock.
Another few weeks and the youngsters will have fledged and the island become a much quiter place.
