Today we observed in our garden in Hondón de las Nieves an Isabelline Warbler (Iduna Opaca). Formerly this species was called Western Olivaceous Warbler (and then it was a Hippolais opaca), but according to the new Collins Guide we have to use the new name. This is a new species for the Migration List. In the Costa Blanca area it is not a common bird, but according to the map in the ‘Ocells de Catalunya, País Valenciá i Balears’ it is in Hondón de las Nieves close to the limit of its breeding area.
