About Curruca subalpina (Temminck, 1820)
Moltoni's warbler (scientific name: Curruca subalpina (Temminck, 1820)) is similar to the Western subalpine warbler. Male Moltoni's warblers have salmon pink underparts, while male Western subalpine warblers have orange underparts. Females and juvenile Moltoni's warblers are almost identical to female and juvenile Western subalpine warblers. The most significant difference between the two species is their vocalisations. Moltoni's warbler's song is faster paced and higher pitched than the Western subalpine warbler's song; it consists of a rapid succession of insect-like notes, and includes the typical dry "trill zerr" call within the song. Moltoni's warbler breeds in areas around the Tyrrhenian Sea in the Mediterranean, specifically on the Balearic Islands, Corsica, Sardinia, and in northern Italy. It winters in the western Sahel, between the Atlantic coast, Niger, and northern Nigeria. It occurs as a vagrant in northwestern Europe. Moltoni's warbler breeds in Mediterranean scrubland, and winters in semiarid savanna dominated by acacia.
