Abstract:

First successful breeding of the Glossy Ibis in the Boussedra wetland (El-Bouni near Annaba) in northeastern Algeria. The breeding occurred in a mixed colony of herons located in Tamarix gallica trees. The birds were present from mid March to mid July. 124 nests were censused, most of them (55.64 %) contained 4 eggs. Egg laying occurred from 4 April to 27 May 2014. Breeding success was of 92 %.

Le résumé: (de la communication affiché de Wahiba Boudraa présentée lors du 3éme Colloque International sur l’Ornithologie Algérienne à l’aube du 3ème millénaire (les oiseaux et leurs milieux):

Le marais de Boussedra (55 ha) est une zone humide périurbaine située dans la commune d’ElBouni, wilaya d’Annaba (Nord-est de l’Algérie). Elle héberge chaque année quelques 53 espèces d’oiseaux d’eau appartenant à 15 familles, dont la famille la plus représentée est celle des Anatidés une douzaine d’espèces. L’Ibis falcinelle Plegadis falcinellus est le seul de représentant de la famille des Threskiornithidés. Après une absence totale depuis plusieurs années, l’espèce s’est installée en Afrique du nord et a commencée à nicher depuis les années 2000. Elle niche avec des effectifs faibles dans des zones éloignées. Au niveau de la zone humide de Boussedra, elle est observée avec des effectifs avoisinant 160 individus. Au cours de la saison de reproduction de l’année 2014 (entre mars et juillet), cette espèce a nichée dans une héronnière mixte (Héron garde-bœufs Bubulcus ibis, Aigrette garzette Egretta garzetta, Bihoreau gris Nycticorax nycticorax, Crabier chevelu Ardeola ralloides et Blongios nain Ixobrychus minus) où un total de 120 nids ont été dénombré. Ceci représente la plus grande colonie observée en Afrique du nord. La reproduction a eu lieu dans une tamaricacée à Tamarix gallica qui a supporté plus de 2000 nids.

Distribution patterns of ectoparasites of Glossy Ibis (Plegadis falcinellus) chicks

Abstract:

The aim of this study was to identify the ectoparasite community that may be found on the body of Glossy Ibis chicks Plegadis falcinellus in two Algerian wetlands, Chatt and Lake Fetzara, during the breeding season of 2010. Birds were parasitized by the following chewing lice (Phthiraptera: Amblycera, Ischnocera) species at both study sites: Plegadiphilus plegadis and Colpocephalum leptopygos (both Menoponidae), Ardeicola rhaphidius and Ibidoecus bisignatus (both Philopteridae). In addition, one tick (larva) Ixodes ricinus was also found at Lake Fetzara. All these ectoparasites were recorded in Algeria for the first time. Results showed that chewing lice varied in their spatial distribution at the infracommunity level with some species displaying no microhabitat preferences, whereas others confined themselves to specific body parts of their hosts. The recorded frequency pattern of chewing lice followed the negative binomial distribution.

Abstract:

The study of the reproduction of the Glossy Ibis (Plegadis falcinellus) in Tunisia was undertaken from 2008 to 2010. Until the discovery of nesting in 2008, this species had only been considered as wintering in Tunisia. The Tunisian breeding population resides in the Lebna Dam in the north east of the country where it forms a mixed nesting colony with other species of the family Ardeidae ((Bubulcus ibis (Bi): 388 pairs, Ardeola ralloides (Ar): 17 pairs, Egretta garzetta (Eg): 27 pairs), (Bi: 300 pairs, Ar: 25 pairs, Eg: 40 pairs) and (Bi: 400 pairs, Ar: 30 pairs, Eg: 10 pairs) recorded in 2008, 2009 and 2010 respectively). All nests were constructed on Acacia horrida. Laying began in early May. The average clutch size over the three years of the study was 3.44 ± 0.73 eggs (N = 29 nests). Hatching success was 83 % (2.86 ± 1.18 eggs hatched/nest) and 2.65 ± 1.17 hatchlings/nest survived until the age of 10 to 12 days. Egg mortality was 17% during the incubation phase and chick mortality was .2%. No interannual variation was detected in these parameters.

First banding scheme of Glossy Ibis (Plegadis falcinellus) in Algeria

Abstract:

Over the last decade, the Glossy Ibis has staged a come-back in Algeria after an absence lasting almost a century. The breeding was recorded in the year 2002 and in the period 2003-2008 the breeding population has been monitored at four sites across the wetland complex of Numidia, north-east Algeria. In order to increase our knowledge of the causes underlying fluctuations in the dynamics of local colonies, a banding scheme of Glossy Ibis chicks was started in 2008, for the first time in North Africa. A total of 72 chicks of a c.100 breeding pairs estimated in three distinct colonies were banded.
