Балеарская славка Curruca balearica

Only occurs on the Balearic Islands. A dark gray, long-tailed, and big-headed warbler. Red eye ring is distinctive. Differs from Marmora’s Warbler (of which it was formerly treated as a subspecies, and a scarce passage bird in the Balearics) in having buffy flanks and a light gray throat on breeding males. Typically found on scrubby hillsides and rocky coastal scrub, usually avoids woodlands. Primarily forages on the ground. Short song is composed of rattling whistles. Gives low “chrk” call.
