摘　　要：Many populations of the Moustached Warbler (Acrocephalus melanopogon) have suffered a noticeable decrease over the last decades. This work has the aim of estimating the home range of the Moustached Warbler and its habitat use during the reproductive season. We captured 11 males during the reproductive period with mist nets and marked them with radio transmitters. We determined the home range by calculating minimum convex polygon and kernel areas at 95% (home range) and 50% (core area). Then, to study the habitat use, we registered the proportion of the different vegetation types within these areas and carried out a compositional analysis to investigate if there is a detectable habitat preference. The results seem to indicate that the marked individuals did not show territorial behavior, given that the overlaps between home ranges and also the core areas were over 70%. The compositional analysis showed that A. melanopogon prefers tall and short reeds and mixed vegetation with rushes and bulrushes. Thus, maintaining heterogeneous and stratified vegetation would favor this species.Many populations of the Moustached Warbler (Acrocephalus melanopogon) have suffered a noticeable decrease over the last decades.
