Potamia Valley, Lesvos,
12' 40.6" N 26° 10' 09.8" E 16
from an olive grove. Song composed of long strophes
of around 30 seconds of scratchy and squeaky elements.
Not unlike Eastern Olivaceous Warbler but overall
narrower frequency range sounding slightly lower in
pitch (though not as low and 'crunchy' as Olive-tree
Warbler), longer strophes (shorter, with more pauses
in EOW), faster with 4-7 elements/sec (EOW 8-10 elements/sec).
