Hamlaoui, B., Rouaiguia, M., Zebsa, R., Kafi, F., Haddad, S., Lahlah, N. & Houhamdi, M. (2016). On the breeding ecology of House Martins Delichon urbica (Linnaeus 1758) in Northeast Algeria. Zoology and Ecology 26: 77–84.  doi: 10.1080/21658005.2016.1149350
PDF

Abstract:

The study of the reproductive biology of House Martins Delichon urbica was carried out in the cities of Guelma and Hammam Debagh, Northeast Algeria during two years 2013 and 2014. Birds of this species produce two broods per year and per breeding pair. At both study sites, the egg-laying period lasted for almost four months. Egg weight and volume differed between broods and years. The mean clutch size was 3.87 ± 1.29, 4.19 ± 1.02 in Guelma and 3.93 ± 1.13, 3.64 ± 1.30 in Hammam in 2013 and 2014, respectively, with a seasonal decline. Hatching success reached 69 and 74.25% in Guelma, and 74.20 and 63.39% in Hammam in 2013 and 2014, respectively. Fledging success was 64.57 and 72.62% in Guelma, whereas, in Hammam it was 72.22 and 58.16% in 2013 and 2014, respectively. Hatching failure was the main cause of mortality. The breeding parameters and morphometrics of the House Martin’s eggs in Algeria determined during our study differed from those reported in previous studies carried out in different parts of Europe.

 

La reproduction de l’Hirondelle rustique (Hirundo rustica) dans un milieu urbain nord-africain

Haddad, S., Hanane, S. & Houhamdi, M. 2015. La reproduction de l’Hirondelle rustique (Hirundo rustica) dans un milieu urbain nord-africain: quel impact des conditions climatiques et de l’application des insecticides ? Revue d’Ecologie (Terre et Vie) 70(3): 280-290.

Summary:

Breeding performance of the Barn Swallow (Hirundo rustica) in a North African urban area: what are the impacts of climatic conditions and insecticide applications? The present study examined the effects of climate conditions (temperature, precipitation and wind speed) and human activity (insecticide treatment) on clutch size, number of hatchlings and total productivity of the Barn Swallow in a North African urban area (Guelma, Algeria). Our results demonstrated that climatic conditions did not clearly affect reproductive parameters of this Hirundinidae, unlike insecticide treatments inside nesting-buildings. A seasonal decline of the three studied parameters was recorded. The number of hatchlings and total productivity were greater for first than for second clutches. Likewise, productivity significantly decreased in 2013 compared to 2012. Further research on other environmental factors such as: (i) insect availability; (ii) agricultural activity and (iii) adverse weather events, are an essential track for the implementation of management measures to improve local breeding conditions of this North African urban population.

Résumé:

La présente étude analyse les effets des conditions climatiques (température, précipitations et vitesse des vents) et de l’activité anthropique (traitements aux insecticides) sur la taille de ponte, le nombre d’œufs éclos et la productivité totale de l’Hirondelle rustique dans un milieu urbain Nord-Africain (Guelma, Algérie). Les résultats ont démontré que les conditions climatiques n’affectent pas clairement les paramètres de reproduction de cet Hirundinidé, contrairement aux traitements insecticides des bâtiments de nidification. Les trois paramètres étudiés ont tous subi une importante diminution au fur et à mesure de la progression de la saison de reproduction. Le nombre d’œufs éclos et la productivité totale ont été plus grands pour la première ponte que pour la seconde. Cette productivité a nettement diminuée en 2013 par comparaison à 2012. La poursuite des recherches sur d’autres facteurs environnementaux comme : (i) la disponibilité des insectes ; (ii) l’activité agricole et (iii) les événements météorologiques défavorables, s’avère une piste incontournable pour la mise en œuvre de mesures de gestion visant l’amélioration des conditions locales de reproduction de cette population urbaine Nord-Africaine.

Kaf, A., Saheb, M., & Bensaci, E. (2015). Preliminary data on breeding, habitat use and diet of Common Kestrel, Falco tinnunculus, in urban area in Algeria. Zoology and Ecology 25(3): 203–210.  doi: 10.1080/21658005.2015.1057989

Abstract:

The nesting of the Common Kestrel, Falco tinnunculus, was monitored in an urban environment (University of Oum El Bouaghi, 35°52′46″ N, 7°05′28″ E) over three successive years from 2011 to 2013. The mean clutch size was 5.75 eggs/nest. The incubation period was spread over at least 27 days. The hatching success was 0, 50 and 60.83% for the years 2011, 2012 and 2013, respectively. The size of the hunting area was between 5.92 and 255.07 ha. The diet analyses of Common Kestrel adults showed that their foods included grasshoppers (31.49%), snakes (12.7%), lizards (21.35%) and rock dove chicks (34.45%).

Nest-site selection and reproductive success of the Little Grebe (Tachybaptus ruficollis) in Northeast Algeria

Athamnia, M., Samraoui, F., Kelailia, B., Rouabah, A., Alfarhan, A. H. & Samraoui, B. (2015). Nest-site selection and reproductive success of the Little Grebe Tachybaptus ruficollis in Northeast Algeria. Ardeola 62: 113–124.

PDF in ResearchGate.net

Summary:

We studied the phenology, habitat selection, and interannual and seasonal changes in breeding performance of the little grebe Tachybaptus ruficollis in relation to the spatial structure of a shallow lake during three breeding seasons (2010–2012). Nests were mostly located in shallow waters, close to the shore (98.3 ± 37.9 cm), in vegetation dominated by Scirpus lacustris. The egg-laying period started at the end of March and extended for four months until the end of July. Overall, the mean clutch size was 4.7 ± 1.1 (N = 154) with a modal clutch of 5. There was a seasonal decline in both egg volume and clutch size. The overall nesting success was 60% and the chief causes of nest failure were predation (52%) and adverse weather (20%). Breeding outcome was influenced by water depth, nest size and year of breeding. Predation and nest flooding markedly varied between years. Larger nests had a higher nesting success than smaller ones. Likewise, nests located at greater water depth (further from the shore) succeeded better than ones located in shallower water. As the little grebe forages preferentially in shallow waters, these results suggest that optimal nesting locations may be the result of a trade-off between conflicting selection pressures such as foraging efficiency (better in shallow waters) and nest predation risk (greater in shallow waters).

Résumé:

Sur la zone littorale de Rabat-Bouznika, des dénombrements réguliers, de janvier 1999 à décembre 2001, ont permis de définir le rythme de migration des espèces d’oiseaux d’eau les plus fréquentes ainsi que leurs statuts phénologiques. Quarante neuf espèces ont fréquenté le site, dont 24 régulières. Les Limicoles et les Laridés sont les groupes les plus dominants. Le suivi de la reproduction a concerné l’Oedicnème criard, la Glaréole à collier, le Gravelot à collier interrompu et la Sterne naine. Ces quatre espèces déposent leurs œufs à même le sol avec une production d’œufs/nid qui avoisine 2 : 1,88 pour l’Oedicnème criard, 2,20 pour la Glaréole à collier, 2,89 pour le Gravelot à collier interrompu et 2,51 pour la Sterne naine. La ponte débute à la dernière décade de mars pour l’Oedicnème criard et le Gravelot à collier interrompu suivi, à la première quinzaine d’avril, par la Glaréole à collier et au début mai par la Sterne naine. Le maximum de l’activité reproductive est enregistrée durant les mois de mai et juin. La durée de la saison de reproduction est plus étalée chez les nicheurs sédentaires (Oedicnème criard et Gravelot à collier interrompu) que chez les migrateurs nicheurs (Glaréole à collier et Sterne naine). Le succès à l’éclosion a été de 49% chez la Glaréole à collier, de 51.5% chez la Sterne naine, de 58.4% chez le Gravelot à collier interrompu et de 71% chez l’Oedicnème criad. Sur cette portion de côte, les plus importants facteurs d’échec ont été le piétinement, le ramassage et l’abandon des œufs. Malgré ces sources de dérangements, la zone littorale de Rabat-Bouznika continue à accueillir une centaine de couples d’oiseaux d’eau nicheurs.

An overview of the Rallidae of Algeria with particular reference to the breeding ecology of the Purple Swamp-Hen (Porphyrio porphyrio)

Samraoui, F., Nedjah, R., Alfarhan, A. H. & Samraoui, B. 2015. An overview of the Rallidae of Algeria with particular reference to the breeding ecology of the Purple Swamp-Hen Porphyrio porphyrio. Wetlands Ecology and Management 23: 505-517.  doi: 10.1007/s11273-014-9404-0
PDF in ResearchGate.net

Abstract:

Rallids are good biological models to monitor anthropogenic changes to wetlands. The distribution of the Rallidae was mapped up during a survey of all major wetlands across Algeria and nest site selection, phenology, and breeding parameters of the Purple Swamp-Hen Porphyrio porphyrio were monitored at two distinct sites under contrasting conditions. Data were collected at Boussedra, an unprotected freshwater marsh during the years 2005 and 2008, and at Lake Tonga, a protected freshwater marsh during 2009. The onset of egg-laying was found to occur earlier (mid-February) than was recorded previously (end-March). There was much variation in the egg laying patterns and in the clutch sizes which dropped significantly from 5.8 ± 0.9 (Boussedra 2009) to 3.4 ± 0.9 (Boussedra 2008) and 3.9 ± 1.0 (Tonga 2009). This study, the first investigation of the ecology and conservation of the Purple Swamp-Hen in North Africa, suggests a decline in breeding success associated with steady habitat loss and ineffective enforcement of legislation.

Breeding biology of the European Greenfinch (Chloris chloris) in the loquat orchards of Algeria

Bensouilah, T., Brahmia, H., Zeraoula, A., Bouslama, Z., & Houhamdi, M. (2014). Breeding biology of the European Greenfinch Chloris chloris in the loquat orchards of Algeria (North Africa). Zoology and Ecology 24(3): 199–207. doi:10.1080/21658005.2014.934514

Abstract:

Few data are available on passerines’ breeding in farmlands in Algeria. The breeding biology of the Greenfinch was studied in the loquat orchards to describe the timing of breeding, clutch size, number of nestlings hatched and fledged, assess nesting success and the main causes of nesting attempt failure, and investigate nest placement in the loquat trees. Nests were monitored intensively to quantify the number of nesting attempts and territory densities. The breeding season extended from mid-March to late May. Mean clutch size was 4.37 ± 0.04, number of hatchlings was 2.62 ± 0.15, and number of fledglings per successful nest was 3.44 ± 0.16. Clutch size differed significantly across the breeding season. The density of breeding pairs was 12.83 ± 0.83 p/ha, and breeding success was lower than that reported in other studies of finches and passerine birds. Predation was the cause of most nest failures. Loquat orchards seem to be the main suitable breeding habitat for the Greenfinch, and differences in some breeding biology characteristics between Algeria and European countries may be explained by climate and latitude.

Breeding ecology of the Atlas Pied Flycatcher in an old oak forest in northeastern Algeria

Boudeffa, K., Brahmia, Z. & Benyacoub, S. (2014). Breeding ecology of the Atlas Pied Flycatcher Ficedula speculigera in an old oak Quercus suber forest in northeastern Algeria. Bird Study 61 (1): 73–81.
doi: 10.1080/00063657.2013.876971 (Free access)

Abstract:

Capsule: Low clutch size (CS) in the Atlas Pied Flycatcher breeding in evergreen Mediterranean forest was compensated for by relatively high overall reproductive success.

Aims: To describe the breeding ecology of the Atlas Pied Flycatcher Ficedula speculigera in detail for the first time, in an old oak Quercus suber forest.

Methods: A total of 102 nests were monitored during 2010–2012. Breeding phenology, population density, clutch and brood sizes, egg biometrics, breeding losses and breeding success were accurately determined.

Results: The species arrived in the breeding area in late April. Population density was very high with 4.87 (±1.02) pairs/ha. Mean egg laying date (LD) was 19 May and CS averaged 4.92 eggs. Hatching and fledging success were 88.7% and 83.5%, respectively. The number of fledged young averaged 3.8 (±1.66) and decreased with LD (4.2 ± 1.45 chicks fledged per nest at the start of the season versus 2.8 ± 1.56 at the end).

Conclusion: Lower CS compared to Ficedula hypoleuca populations was compensated by relatively high fledging success, thereby ensuring overall reproductive success of this species. Moreover, the Atlas Pied Flycatchers seem to benefit from the lower seasonality in their food in the evergreen habitat.

Nefla, A., Ouni, R., & Nouira, S. (2012). The Breeding Status of the Glossy Ibis Plegadis falcinellus in the Lebna Dam in Cap Bon, Tunisia. Journal of Life Sciences 6: 776–782.   PDF

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.
