Birds in Spain
Jacob González-Solís & Laura Zango
On 28.6.2013, while conducting a research on Cory's Shearwater (Calonectris diomedea) breeding colony at Montaña Clara, an islet of the Chinijo archipielago North of Lanzarote, Canary islands, an individual of Cape Verde Shearwater (C.edwarsii) was found (Zango & González-Solís 2013). The bird was not ringed because the '6' model for diomedea does not fit this species and it was not checked if it had brood patch or not but it was in an area within the colony frequented by non-breeding individuals so it is not believed to be actively nesting.
Photos show the individual and differences with a Cory's Shearwater of the same colony.
This is the 3rd proven and due for acceptance record for Spain, the two previous coming from the same site and colony back in 2010. As from CR-SEO/BirdLife rarities report for 2010 published in Ardeola journal:
The 2013 bird was trapped again on 2.7.2013. It was ringed then with a 6 ring 6215207. Tarsus was 50.0 mm, Culmen 44,2 mm, Bill height 16.0 mm, and bill height in front of narina was 11.9 mm. Bill to skull 96 mm, Wing 314 mm and weight 445 mm. Brood patch was regrowing and it has not been apparently breeding.
