The subdesert brush warbler, also known as Lantz's brush-warbler, is a species of Old World warbler in the family Acrocephalidae. It is found only in Madagascar.
Region
Southwest Madagascar
Typical Environment
Occurs in subdesert and spiny thicket habitats characterized by Didierea and Euphorbia shrubs, as well as dry coastal scrub and bushy dune margins. Favors dense, low vegetation and ecotones along tracks and the edges of thickets. It also uses degraded scrub and lightly disturbed areas where cover remains. Populations are concentrated from around Toliara south toward Lake Tsimanampetsotsa and adjacent plateaus.
Altitude Range
Sea level to 300 m
Climate Zone
Arid
Ease of Keeping
Beginner friendly: 1/5
Endemic to the subarid spiny thickets of southwestern Madagascar, this skulking warbler is often detected by its loud, varied song before it is seen. It keeps low in dense, thorny scrub and flicks its long tail while foraging. Habitat loss from charcoal production and clearing is a concern locally, but the species persists in several protected areas.
Temperament
skulking yet curious near cover
Flight Pattern
short rapid wingbeats low over scrub
Social Behavior
Typically solitary or in pairs, holding small territories in dense scrub. Builds a neat cup nest low in thorny shrubs or grass clumps. Both parents attend the young, and the male often sings from a semi-concealed perch.
Migratory Pattern
Resident
Song Description
A loud, varied series of whistles, trills, and chattering phrases delivered from cover or low perches. Calls include sharp tacks and scolding churrs, often repeated in quick sequences.
