The Leach's storm-petrel is a small and secretive species that is rarely seen by visitors to the island due to its nocturnal behaviour and nesting habits in burrows and amongst rocks.
The sound they produce at night is, however, very distinctive and that's why Work Party 1 and I decided to head out one evening to try and listen to them. We gathered together at 10pm but it was still far too light to head off so we passed the time skimming through old bird books and listening to some awful jokes!
We could see relatively well on the way to the petrel site so we stopped to look out over Gleann Mor and to investigate some old owl pellets.
All was quiet to begin with but after a short while we heard the delightful, but completely ridiculous, sound of a petrel chuckling from inside a wall (click here
for an example clip). We moved slowly up the hill eventually stopping amongst a little cluster of cleits and it was there that the petrels put on their most spectacular performance. They called, churred and chuckled and even in the darkness we coud see birds fluttering about above us - some appeared to be mere inches over our heads! Just after 1am we decided to leave the birds and head home. On the way back down the road we heard the other species of petrel that nests on the island calling nearby..... Amazing.
