Let’s start with the question that must be on all our minds: who was Cory? Was he the now-retired bird blogger? Or the Filipina businesswoman Cory Vidanes?

Both these people deserve to have a shearwater named after them, but the eponymous honour belongs to Charles Barney Cory. For scientific names it is a faux pas to name something after yourself, but in English a bird can be named after the “discoverer”. Charles (Chuckie for friends) Cory was an American ornithologist, golfer, outdoorsman, and author, according to Wikipedia. Dr Jekyll and Mr Hide, both a boorish ornithologist and a boring golfer. Or as an English comedian once put it: it’s a dessert topping AND a floor cleaner! The same bird has been named after Heinrich Kuhl in Dutch, while most other nations refer to its Atlantic Ocean home, its yellow bill or the Canary Islands (we will get back to that one later on). In Portugal – very woke – it is masculine on the islands (cagarro) and feminine on the mainland (cagarra). Considering all this confusion, Linnaeus came up with the scientific nomenclature, so Calonectris borealis it is. Give that man a statue!

The confusion hasn’t stopped at the naming – when I first heard the eerie sounds of shearwaters on the island of Gozo back in the eighties, there was only Scopoli’s Shearwater with some sub-species. For the listers amongst us the news has been nothing but good: we now have Scopoli’s, Cory’s and Cape Verde Shearwaters.

With the Treaty of Alcáçovas, the Castilian control of the Canary Islands was confirmed (nobody asked the natives as they had been exterminated). This has turned out to be a grave mistake for without the treaty all Cory’s Shearwaters would have been born in Portuguese-speaking territories (and most of them winter in Portuguese-speaking Brazil). What a great pub quiz question that would have made! Castilians even named the bird pardela canaria which is pushing it considering the distribution of the species. To make amends for this gross act of cultural appropriation, SEO/BirdLife, la Sociedad Española de Ornitología is doing a tremendous job with bird conservation on and around the islands. Gracias!

Cory’s Shearwaters are long-living seabirds which has helped them survive human mismanagement and outright abuse. Fishermen on the Atlantic islands used to collect the chicks to use as bait for long-lining, but with the better legal framework and increased awareness the birds have become the unofficial symbol of the islands. The species is now classified as Least Concern. SPEA and SEO run campaigns against light pollution (distracts the fledglings), against introduced predators and much more. During fledging season, the organisations set up boxes all over the islands to collect stranded fledglings. Volunteers descend cliffs to salvage birds. I have been fortunate enough to hold such a rescued Cory’s Shearwater in my hands, which is really special – you usually see them fly past at great speed. So, if you see a Cory’s Shearwater on a pelagic birding trip off the Massachusetts seaboard: think about the work on the Atlantic islands that got it there.

Peter Penning is a sustainability management consultant who spends many weeks abroad away from his homes in The Netherlands (work) and Portugal (holidays). Although work distracts him regularly from the observation of birds, he has managed to see a great many species regardless. He firmly believes in the necessity of birders to contribute to conservation. He passively supports BirdLife in the Netherlands and South Africa and actively in Portugal as treasurer of SPEA – Sociedade Portuguesa para o Estudo das Aves. Peter likes to meet people and have good after-birding lunches which has seriously hampered his ability to build up a truly impressive life list. Somehow, he doesn’t care.
