Diet and nesting morphometric analysis of reed warbler Acrocephalus scirpaceus (Hermann, 1804) near the lake of Reghaia Algeria.

We investigated diet and nesting morphometric in a population of reed warbler (Acrocephalus sciepaceus) living near the lake of Reghaia, North of Algeria. Diet was estimated by analysis of fecal samples (34 feces) During the year 2014-2015. Faecal samples were collected and treated separately in 70% alcohol to identify prey-species. In total, 181 prey items of 55 different species were found classified into 5 classes, 12 orders and 39 families. Insects were the most dominant preys (87.85%), followed by Arachnida (7.18%). The basic component of the diet was Hymenoptera (33.15%), followed by Coleoptera (14,92%), Diptera (11.05%) then Homoptera (9.94%) and Heteroptera (8.29%). Concerning the nesting morphometric analysis, the measuring of 14 nests leads to find an external diameter varying between 64 and 90 mm, an inner diameter fluctuating between 43 and 70 mm, and a height between 55 and 95 mm The distance between the nests and the ground through, varied between 0.98 and 2.94 m. The nests were placed on Phragmites communis.
