Iberian chiffchaff Iberian chiffchaff The Iberian chiffchaff ("Phylloscopus ibericus") is a species of leaf warbler endemic to Portugal, Spain and North Africa, west of a line stretching roughly from the western Pyrenees via the mountains of central Spain to the Mediterranean. The name "chiffchaff" is onomatopoeic, referring to the repetitive "chiff-chaff" song of the common chiffchaff ("Phylloscopus collybita"). There are similar names in some other European languages, such as the Dutch "Tjiftjaf", the German "Zilpzalp" and Welsh "siff-saff". The genus name "Phylloscopus" is from Ancient Greek "phullon", "leaf", and "skopos", "seeker" (from "skopeo", "to watch"). The specific "ibericus" is Latin for "Iberian".
Handbook of the Birds of the World a non-profit endeavour fuelled by material from more than one hundred contributors from around the world. In early 2013, Lynx Edicions launched the online database HBW Alive, which includes the volume and family introductions and updated species accounts from all 17 published HBW volumes. Since its launch, the taxonomy has been thoroughly revised and updated twice (once for non-passerines and once for passerines), following the publication of the two volumes of the "HBW and BirdLife International Illustrated Checklist of the Birds of the World". The Handbook of the Birds of the World Alive site also provides a free access 'Key
