Key Identification Features
- When measuring birdsong complexity by the number of distinct notes, the high song complexity of Blyth's leaf warbler results from increased variation between its different song types.
- Its most distinctive call is a two-note dir-tee, where the second note is much higher in pitch.
- This resemblance to the willow warbler is strengthened by the presence of a distinct dark eyestripe.
- In Portugal, it occurs mainly in the northern regions of Trás-os-Montes and Alto Douro, with another distinct breeding population in southern Portugal from Estremadura south to the Algarve.
