Dear Readers, it’s not all about the whales you know – Cory’s Shearwater is the bird that you’re most likely to see at sea. We often saw them resting in great rafts, eventually lifting themselves into the air when they saw the boat approach. The way they ran a few steps on the waves before gently lifting off was very endearing.

Cory’s Shearwater breeds only in the North Atlantic, with the Azores, Canaries and Madeira being their main breeding grounds. The fascinating thing is that at sea, these birds are completely silent, but last night we went to visit the rocky outcrops and cliffs where the birds nest. For most of the year they range widely over the whole Atlantic, with different birds following different migration paths, some reaching as far south as Patagonia, others veering off towards the UK and even Madagascar. However, the birds are monogamous and find one another at their nesting site every year, where they raise one fat, fluffy chick. They all leave in the autumn, and the one-in-ten of the chicks that survive will return to their original nesting ground.
What is truly remarkable is the sound that they make as they come into land at the end of the day. The male and the female have different calls, but each bird is unique, and their call helps them to find one another. Sometimes they’ve just been fishing separately for the day, but sometimes they are finding one another after months apart (the pairs often have different migratory locations). I have never heard anything like it. See what you think. You won’t be able to see the birds, but you’ll certainly be able to hear them. For some reason it made me cry, and laugh, simultaneously. Each recording is slightly different.
Sadly, a big problem for Cory’s Shearwaters is the increasing level of light pollution, and a campaign to encourage the turning off of unnecessary lights has been waged in the Azores and the other Atlantic islands. Sadly it doesn’t seem to be working that well on the island of Faial, right opposite where the birds I heard are nesting. We found two downed and disorientated shearwaters just sitting on the road as we made our way back. Fortunately we were able to shoo them back towards the rocks (and hopefully they’ll sort themselves out at day break) but you can see what a problem it will be when the chicks fledge. Let’s hope that more places learn to turn the lights off.
