Zino’s / Fea’s Petrels key identification

I just want to let you know that there is an extensive report of Hadoram Shirihai article on last Birding World in the Madeira Wind Birds website… Hadoram??describes his sea experience with Zino’s Petrel and writes about some key identification marks between Fea’s/ Deserta and the Zino’s Petrel he has observed. Also, very nice pictures of what is known to be the first picture of a Melanistic morph of a Blackcap on the wild…Have a look at??www.madeirabirds.com
