Abstract:

An ecological study of the Northern Shoveler Anas clypeata in the wetlands of the Guerbes-Sanhadja eco-complex (Skikda, north-eastern Algeria) which was performed during wintering season (from September 2012 to March 2013) showed that the species was regularly wintering in these ecosystems during the seven months of observation. The highest numbers were recorded during December 2012 (1943 individuals) at Garaet Hadj-Taher, although this wetland was the last to be colonized if we compare it to other wetlands. Garaet Hadj-Taher hosted more than half of the wintering population of the Northern Shoveler in the Guerbes-Sanhadja eco-complex. Sleeping activity (diurnal resting) dominated over other diurnal behaviours of this Anatidea at Garaet Hadj-Taher by representing almost two-thirds of total results (63.74%). This activity was observed among gathered individuals in the centre of this wetland. The second place was taken by swimming (15.10%) followed by preening (10.49%), feeding (7.03%) and finally flying (3.64%), showing the results of diurnal counting for the Northern Shoveler in Garaet Hadj-Taher and all other wetlands in the Guerbes-Sanhadja complex.

Abstract:

In Algeria, the Globally Endangered White-headed Duck Oxyura leucocephala is resident throughout the year in the coastal wetlands of north-east Algeria and the Hauts Plateaux, where it occupies habitats that range from freshwater ponds and brackish marshes to hypersaline lakes. In autumn and winter, at two study sites sleeping (49% and 68%) and resting (9% and 20%) dominated, whereas feeding (7% and 10%) represented a minor proportion of, diurnal activities. There was no marked seasonal change in the activity pattern, as would be expected for a resident bird. The breeding and winter distributions of the species were similar, but seasonal and diel patterns of dispersion among habitats remain poorly known. Human encroachment on wetland habitat, habitat degradation and illegal hunting in protected areas are the major threats to the persistence of the species and probably similar threatened species in Algeria.

Diurnal behaviour of breeding White-headed Duck (Oxyura leucocephala) at Lake Tonga, Algeria

Lazli, A., Nouari, I., Chater, N. & Moali, A. (2014). Diurnal behaviour of breeding White-headed Duck Oxyura leucocephala at Lake Tonga, North-East Algeria. Revue D’écologie 69 (2): 131–141.

Résumé :

Le comportement diurne de l’Érismature à tête blanche Oxyura leucocephala a été étudié au lac Tonga, lac d’eau douce peu profond situé dans le Nord-Est algérien, au cours de deux saisons de reproduction. Les rythmes d’activités diurnes de 173 oiseaux ont été compilés, de la période de pré-nidification jusqu’à la mue postnuptiale. Des budgets d’activités séparés ont été construits pour chacun des mâles et des femelles d’Érismature. Durant la saison de reproduction, le sommeil s’est avéré être la principale activité diurne pour les mâles (40 %), ce qui reflète l’avantage de la thermorégulation au cours du repos pendant la journée. Les femelles se nourrissent plus que les mâles (respectivement 26 % et 19 %) au cours de la période de pré-nidification, indiquant ainsi leur besoin d’acquérir des nutriments et de l’énergie pour la production d’œufs et l’incubation. Les parades nuptiales et le comportement agonistique, plus importants pendant la pré-nidification (période de ponte et d’incubation), indiquent que certains mâles tenteraient de copuler avec d’autres femelles, alors que d’autres essayeraient de protéger leurs propres femelles contre cela. L’augmentation du temps imparti à la toilette à partir de juin et juillet pour les deux sexes indique le début du phénomène de mue. L’activité alerte est plus importante pendant la période postnuptiale. En effet, mâles et femelles d’Érismature allouent un même temps à la protection des poussins et des juvéniles contre différents ennemis. Ce travail présente des données récentes et inédites sur l’éco-éthologie d’une espèce menacée pendant la saison de reproduction et dont les études sur le sujet restent peu développées dans la nature, en particulier pour chaque sexe.

Ecologie de la Sarcelle Marbrée Marmaronetta angustirostris (Ménétries, 1832) dans l’éco-complexe de zones humides de la vallée de l’Oued Righ (Sahara algérien). Bulletin de l’Institut Scientifique, Rabat, section Sciences de la Vie 35: 141-149. PDF

Résumé :

Une étude menée sur la Sarcelle marbrée Marmaronetta angustirostris du mois d’août 2007 au mois de juillet 2011 dans les zones humides de l’éco-complexe de la vallée de l’oued Righ (Sahara algérien) a montré le caractère sédentaire de la population nicheuse locale et mis en évidence la reproduction de cette espèce dans la majorité des plans d’eau. A cette population nicheuse locale s’ajoute en saison d’hivernage un nombre important de migrateurs. L’effectif maximal recensé a été de plus de 600 individus, en décembre, et les effectifs les plus bas de moins de 200 individus durant les mois  les plus chauds, soit juin et juillet de chaque année. Le bilan des rythmes d’activité diurne est dominé par l’activité alimentaire, qui représente 55.7 % du total. Elle s’opère à 75 % par basculement du corps du canard contre 25 % uniquement par plongeon de la tête. Cette activité est suivie par la nage avec 10.9 %, l’entretien du plumage (8.3 %), le sommeil (7.6 %), le vol (6.5 %), et les activités de parade (6 %) et d’antagonisme (5 %). De ce fait, les chotts et les sebkhas de la vallée confirment leur rôle de terrain de gagnage diurne. L’espèce niche régulièrement dans les milieux aquatiques sahariens étudiés. La période de nidification s’étale de la fin mars à la fin juin. Les nids sont édifiés dans les touffes de Salicornia fruticosa, Salsola fruticosa, Atriplex halimus, au sol sous Tamarix gallica et sur les premières ramifications de ses branches. Ils peuvent contenir jusqu’à 13 œufs.

Ecology of Marbled Teal Marmaronetta angustirostris (Ménétries, 1832) in the wetland complex of Oued Righ valley (Algerian Sahara)

Abstract:

We conducted a survey on the Marbled Teal Marmaronetta angustirostris in the wetland complex of Oued Righ valley (Sahara of Algeria) from August 2007 to July 2011. Our results showed that this species have a sedentary breeder status. The breeding of Marbled Teal was reported in the main wetlands of Oued Righ complex. Further of the local breeding population, an important number of migrating individuals came to spend the wintering season. The maximum of 600 Marbled Teal were observed in December, while less than 200 individuals were recorded in the hottest months of the year (June and July). Feeding was the dominated diurnal behaviour with 55.7 %. This activity was performed mainly by upending (75 %) and sometimes by head dipping (25 %). Which confirm the important role of wetland complex of Oued Righ as a diurnal feeding area. The other less dominant activities were swimming (10.9 %), preening (8.3 %), resting (7.6 %), flying (6.5 %),  courtship (6 %), and agonistic behaviour (5 %). The Marbled Teal breed regularly in most surveyed wetlands. The breeding period stretched from late March to late June. The majority of Marbled Teal nests contained thirteen eggs, settled mainly in tufts of Salicornia fruticosa, Salsola fruticosa, Atriplex halimus on branches near the water and in Tamarix gallica near the shore.

Diurnal behaviour of the Northern Shoveller in winter at two Algerian wetlands: Garaet Hadj-Tahar and Garaet Timerganine

Metallaoui, S., Maazi, M.C., Saheb, M., Houhamdi, M., & Barbraud, C. (2014). A comparative study of the diurnal behaviour of the Northern Shoveller (Anas clypeata) during the wintering season at Garaet Hadj-Tahar (North-East Algeria) and Garaet Timerganine (Algerian highlands). Turkish Journal of Zoology 38: 158-167.  doi:10.3906/zoo-1212-1   PDF 

Abstract:

The rhythms of the Northern Shoveler’s (Anas clypeata Linnaeus, 1758) activities during its wintering period in 2 wetlands, Garaet Hadj-Tahar (North-East Algeria) and Garaet Timerganine (Oum El-Bouaghi, Algerian highlands), were studied during 2 wintering seasons in Garaet Hadj-Tahar from November 2007 to March 2008 and November 2008 to March 2009, and in the Timerganine wetland from November 2007 to March 2008. They were linked to certain spatiotemporal variables, i.e. daytime activities and 2 different wetlands. During the wintering season, the main activity at Garaet Hadj-Tahar was sleeping (70%), followed by swimming (12%). By contrast, feeding was the dominant activity at Garaet Timerganine, occurring 45% of the total monitoring time, followed by sleeping (35%). The frequency of the behaviours did not differ significantly between the sites as a function of the date (P > 0.05). The choice of the site was made according to either the feeding resources or the resting place. These factors are therefore essential and highlight the importance of the protection of the sites where the species is concentrated outside of the breeding period.

Status and diurnal behavior of the Greater Flamingo in Algerian eastern high plains

Bouaguel, L., Saheb, M., Bensaci, E., Bougoudjil, S., Bouslama, Z. & Houhamdi, M. (2013). Status and diurnal behavior of the Greater Flamingo Phoenicopterus roseus in Algerian eastern high plains. Annals of Biological Research 4 (8): 232-237.   PDF

Abstract:

The Grater Flamingo Phoenicopterus roseus has been well studied during the last decade in Algeria leading to highlight some aspects of its distribution, status, movements, and population dynamics. Knowing that an important part of the country has rarely or never been investigated, we studied the status and behaviour of the species in two newly discovered wintering populations (Sebkhat Ouled Amara and Sebkhat Ouled M’barek) in the Northern limit of Sahara, Khenchela, Algeria. The number of individuals was higher in Sebkhat Ouled Amara than Sebkhat Ouled M’barek showing peaks of 8 000 and 1 452 in the winter, respectively. Diurnal activity budget revealed that feeding was the most dominant activity representing 73.5% of all activities. Locomotion, flight, preening, courtship, and resting accounted for 12.3%, 6.2%, 4.0%, 2.8%, and 1.3%, respectively. There was no marked seasonal change in the behaviour of flamingo except for courtship which increased in the breeding season. Diurnal activity rhythms showed that locomotion, preening, and resting decreased in the afternoon while courtship and flight increased.

PDF in ResearchGate.net

Abstract:

Between September 2003 and July 2006, the reproductive biology and time budget of the Ruddy Shelduck Tadorna ferruginea was studied in the wetland complex of Oum el Bouaghi, north-east Algeria. Our results indicate a marked post-breeding dispersal of the Ruddy Shelduck to the eastern Hauts Plateaux where more than 1 000 birds (one-third of the estimated north-west African population) may gather in autumn. Dispersal is again conspicuous at the end of the wintering period when most birds leave the area to return to their breeding grounds. In 2004 and 2005, successful nesting was recorded at five sites. In both years, territoriality was exhibited from March to June and broods, ranging from nine to 14 chicks (mean = 11.1 ± 1.8, N = 16), were recorded between 21 May and 7 July. We also monitored the diurnal time budget of the Ruddy Shelduck over a two-year period. Feeding, most intense in late autumn and winter, occupied 50.6% of the daily activities with a distinct gradual seasonal decrease coinciding with the start of the breeding period. Ruddy Shelduck relied more upon surface feeding in shallow waters but displayed flexibility of feeding behaviour when water level fluctuated.

Atoussi, S., Bara, M. & Houhamdi, M. 2013. Phenology and diurnal behavior of the Tufted Duck Aythya fuligula in Garaet Hadj Tahar (Occidental Numidia, Northeast Algeria). Journal Academica 3 (2): 117-126. PDF

Abstract:

In order to evaluate the number of Tufted Duck Aythya fuligula and its diurnal behavior in Garaet Hadj Tahar (Guerbes-Sanhadja wetlands, Northeast Algeria), this study was carried out during the wintering period (from November to April) in the years 2006, 2007, 2008 and 2009. The peak of the number observed during whole study period was recorded in December 2008 with a value of 100 individuals. The sleeping is the dominant diurnal behavior of the Tufted Duck (32%) followed by the swimming (31%) and feeding (2 5%). These comfort activities are done during the cold period in order to preserve the energetic stock.
