These times were chosen to reflect the main periods of bird activity. The survey method was to walk slowly along paths through the scrub, recording all species seen or heard, but paying particular attention to records of Red-shouldered Vangas. We played a tape of Red- shouldered Vanga song at regular intervals, in an attempt to elicit responses from any birds present. Results and Discussion We located a minimum of nine singing male Red-shouldered Vangas within a 2 km radius of the village of Lintsa (25°00'S 44°24'E), and one singing male was found c. 3 km E of Itampolo (24°41'S 43°58'E). Photographs and sound recordings were taken at both sites. Our record of a singing male Red-shouldered Vanga close to Itampolo is within the known range of the species, as determined by ZICOMA (1999). However, we also found a population close to Lintsa, c. 50 km southeast of the southern limit of the previously known range of the species, extending its known range. Male and female Red-shouldered Vangas are similar to the respective sexes of the Red-tailed Vanga Calicalicus madagascariensis, which inhabits the same region, but there are several distinctive differences (see Hawkins et al. 1997 for details). S. Zefania was familiar with both species, after a previous visit to the region in 1998, and we are confident that our observations were Figure 1.
