Abstract:

The diet of the Common Moorhen Gallinula chloropus was studied at Lake Réghaïa (Algeria). A total of 600 faecal samples were collected from February 2010 to January 2012. The results showed that green plant materials (especially Poaceae) were the dominant faecal components (86.7 ± 23.8%), followed by invertebrates (13.2 ± 23.8%) and grit (0.03 ± 0.05%). Seventeen plant species belonging to eight different families were identified in 2010/2012. The major item identified in faecal contents was Poaceae. Paspalum distichum was the most important diet category. Others grasses mostly eaten were Poa annua, Avena sp., Phragmites sp. and Panicum repens. Other plant species recorded in faeces were Carex hispida, Polygonum lapathifolium, Thypha angustifolia, Plantago major, Mentha pulegium, Plantago crassifolia, Panicum repens and Carex hispida. The Common Moorhen diet contained invertebrates, and ephippium of Daphnia sp. were the most dominant. Insects were recorded, but with a negligible proportion.

Abstract:

The study of the Coot’s (Fulica atra) diet was carried out from February 2010 to January 2012 in the nature reserve of Lake Réghaïa in the eastern part of Algeria. For that purpose, a total of 600 faecal samples, or 300 faecal samples per year, were analysed. The analysis showed that the bird’s food spectrum primarily consists of plant species, animal prey being very rare. Overall, 34 plant species belonging to 17 families and 18 animal species were identified. Thirty plant species belonging to 15 families were identified during the first study period (February 2010–January 2011) and 32 plant species belonging to 17 families were identified during the second study period (February 2011–January 2012). The relative abundance of Poaceae family plants in the Coot’s diet was estimated at 65.1% and that of Cyperaceae and Typhaceae at 7.3 and 4%, respectively. The share of other plant families in the bird’s diet was found to be negligible. The proportion of animal prey in the diet represents 3.1%. Among plants of the Poaceae family, the most favoured are the following three species Paspalum distichum, Phragmites sp. and Panicum repens with rates of 33.2, 18.6 and 15.7%, respectively. The intake of other taxa was lower. Dietary variations during the year coincided with changes in local availability of food and species phenology.

“Les derniers cas de nidification du Fuligule milouin (Aythya ferina) rapportés en Algérie ont été signalés par Heim de Balsac et Mayaud en 1962 au niveau du Lac Fetzara (Annaba) et au Lac Tonga (Parc National d‘El-Kala)……

C’est en avril 2009 que le groupe ornithologique du centre cynégétique de Réghaia a signalé la présence des nids de cette espèce. L’Algérie représente donc une nouvelle zone de reproduction pour le Fuligule milouin. L’étude de l’écologie de la reproduction de six nids installés durant l’année 2010 a révélé une taille de ponte moyenne avoisinant 8,16 œufs/nid. Les nids sont installés dans les touffes de Massettes à feuilles étroites Typha angustifolia…….”.

Abstract:

Breeding evidence of Common Pochard Aythya ferina at Lake Réghaia (North Algeria).

After an absence of nearly 50 years, breeding was again assessed for the Common Pochard in Algeria. Nesting was found in 2009 and 2010 at Lake Réghaia. The six nests found in 2010 showed a mean clutch size of 8.16 eggs/nest. The first hatching occurred in May and the last one in the first week of July. Hatching success was of 66.66 %. The main causes of hatching failure were predation and egg abandonment. Nests are made of Typha and Phragmites leaves.
