# The Portuguese Berlengas Islands support a thousand pairs of Cory's Shearwaters

Miguel Lecoq ([Eco-Ethology Research Unit, ISPA-Instituto Universitário](http://www.ispa.pt/ui/uie/), Lisbon, Portugal) and colleagues writing in the journal *Airo* last year report on the numbers of Cory's Shearwaters*Calonectris diomedea borealis*breeding on the Portuguese Berlengas Islands on the Atlantic coast of the Iberian Peninsula.

 The 2011 survey resulted in an estimated 980-1070 breeding pairs on 10 islands and islets within the archipelago.
