common bird on St Kilda is the puffin, with roughly
270, 000 birds on the islands in summer. They only come
ashore to lay their eggs and look after their young.
Puffins don't nest on cliff edges. Instead they lay
their eggs in burrows which they dig in the green, grassy
slopes at the top of a cliff. The island of Dun is perfect
for them. Here they are protected against predators.
When the pufflings hatch in the summer and begin to
fly, some of them are attracted to the lights on the
buildings. So the St Kilda ranger weighs the birds,
puts an identity ring on them and releases them back
off the end of the pier.
Puffins only have a bright stripy beak in the summer
months. The rest of the year it's a dull yellow colour.
Puffins spend most of their life at sea and are excellent
swimmers. They use their wings to fly underwater, like
penguins do. They are sometimes called 'Tammie Norries'
by people on the islands of Scotland.
