Iberian chiffchaff
phylloscopus ibericus latin

Perhaps the greatest challenge is distinguishing non-singing birds of the nominate subspecies from Iberian Chiffchaff in the field.

It was initially named P. brehmii, but the type specimen of that taxon is not an Iberian Chiffchaff.

Previously the Iberian Chiffchaff was considered as a subspecies of the Common Chiffchaff (Phylloscopus collybita).

"The correct name of the Iberian Chiffchaff Phylloscopus ibericus Ticehurst 1937, its identification and new evidence of its winter grounds".

The song differs from that of the Iberian Chiffchaff, which has a shorter djup djup djup wheep wheep chittichittichiittichitta.

Regarding the latter aspect, it is interesting to note that the Iberian Chiffchaff apparently is the oldest lineage of chiffchaffs and quite distinct from the Common Chiffchaff.

The Iberian Chiffchaff (Phylloscopus ibericus) is a species of leaf warbler endemic to Portugal and Spain, west of a line stretching roughly from the western Pyrenees via the mountains of central Spain to the Mediterranean.
