As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

How Puffin Island's bird population is fighting back from effects of invasion of shipwreck's four-legged stowaways 200 years ago



The colony was ravaged when the ship went down in 1816, and the island's puffin population has never fully recovered

The bird population of Puffin Island has spent 200 years trying to recover from a shipwreck that brought unwelcome stowaways to its shores.

At the peak, more than 50,000 puffins resided on the island, just off the east coast of Anglesey.

But a shipwreck in the 1800s plagued it with brown rats. Their number exploded, and the consequences for the puffins were catastrophic.

To this day, the puffins that give the island its name have never got back up to their previous strength. But work is going on to try to reverse the damage.

An estimated 500,000 rodents were on the island by 1971, virtually wiping out the thriving sea bird population, cutting the number down to around 2000 by 1907, and leaving less than 20 pairs of puffins by the 1990s.

By 1998 the situation got so bad that the Countryside Council for Wales (CCW) and the Royal Society for the Protection of Birds (RSPB) stepped in to eradicate the vermin.

Despite the intervention, according to Puffin Island Seabird Research, there were only eight breeding pairs of puffins left on the island in 2010.
