The Marsh Harrier (Circus aeruginosus) is a ground-nesting migrant raptor (Clarke, 1995) and has a widespread breeding range in Europe as well as in Turkey (Kirwan et al., 2008). Although it is one of the most common raptor species in Turkey, it’s reproductive biology has not been examined. We studied the breeding biology of the Marsh Harrier at the southern border of its distribution, at Acıgöl (37°49'N, 29°52'E), an important wetland complex in southwestern Turkey (Dijksen & Kasparek, 1988). The total surface area of the lake is 150 km2 (Helvacı et al., 2013); the total surface of the reed beds associated with the lake is 759 ha, scattered over 13 different reed beds, each with a surface area of between 3 and 362 ha (potential breeding habitats).This study was carried out during the breeding seasons (March to September) of 2016, 2017, and 2018
