About Locustella lanceolata (Temminck, 1840)
The lanceolated warbler, with the scientific name Locustella lanceolata, is an Old World warbler species belonging to the genus Locustella. It breeds across the Palearctic region, from northeast European Russia extending to northern Hokkaidō, Japan. It is a migratory species, and spends the winter in Southeast Asia. The genus name Locustella comes from Latin, and it is the diminutive form of locusta, the Latin word for "grasshopper". This name refers to the song of the common grasshopper warbler and some other species in the same genus. The specific epithet lanceolata is Latin for "spear-shaped", which refers to the streaks on the bird's breast. This small passerine bird occurs in grassland that has some thicker shrubby vegetation or trees, and it is often found near water in bogs or wet clearings. It lays five eggs in a nest built in a grass tussock. This species is a rare vagrant to western Europe, and Fair Isle, Shetland is one of the best locations to spot this skulking vagrant species. It is a small warbler. Adult individuals have a streaked brown back and whitish grey underparts, which bear small spear-head-like streaks; these streaks are also found on the undertail. As with most warblers, the sexes look identical, but young birds have a yellower colouration on their underparts. Like most warblers, it is insectivorous. This is a skulking species that is very hard to observe, only occasionally visible when singing. It creeps through grass and low foliage. Its song is a monotonous, mechanical insect-like reeling, similar to the songs of other species in this group, and is often produced at dusk. Two subspecies of this species are currently recorded: L. l. lanceolata (Temminck, 1840) and L. l. hendersonii (Cassin, 1858).
