Hadoram Shirihai (Shoham, Israel) and colleagues have published in the journal Dutch Birding on the endemic gadfly petrels of Chile’s Juan Fernández Islands.
“This paper details the special avifauna of Juan Fernández archipelago, off Chile. We visited the archipelago from 3 to 15 March 2013, mainly to study the local gadfly petrels Pterodroma at sea, namely Juan Fernández Petrel P. externa, Stejneger’s Petrel P. longirostris and De Filippi’s Petrel P. defilippiana.”
