Assessing the extinction risk of the great bustard Otis tarda in Africa

Palacín, C., Martín, B., Onrubia, A. & Alonso, J. C. 2016. Assessing the extinction risk of the great bustard Otis tarda in Africa. Endang Species Res 30: 73–82. doi: 10.3354/esr00726 (Open Access)

Abstract:

We studied the dynamics and trend of the last extant population of great bustards Otis tarda in Africa. Moroccan great bustards are the southernmost population of this species, and thus show the characteristics of a peripheral population: small size, isolation and low gene flow. Available counts indicate a severe population decline (62% in the last 15 yr), as well as a contraction of the species’ distribution. We used a population viability analysis (PVA) to evaluate the quasi-extinction risk and to identify the most important threats. The estimated geometric growth rate of the more realistic of a set of possible scenarios was 0.87 (95% CI: 0.85, 0.89). This implies a 13% annual decline over 50 yr. However, projections derived from these results should be interpreted with caution, because models have a great deal of uncertainty and vital rates from Iberian populations may be different from those of the Moroccan population. PVA showed the negative consequence of human-induced mortality. According to the model that best fits our census data and if present threats remain in the coming years, this peripheral population could go extinct in ca. 20 yr. Agricultural intensification, infrastructure developments and new power lines in rural areas where the species occurs are causing habitat destruction and fragmentation and increasing artificial mortality. Urgent conservation measures, especially to reduce human-induced mortality, are needed to save African great bustards from extinction. We suggest that these findings can be generalized to other peripheral great bustard populations living in highly humanized landscapes.

Significant population of Egyptian Vulture (Neophron percnopterus) found in Morocco

Amezian, M. & El Khamlichi, R. 2016. Significant population of Egyptian Vulture Neophron percnopterus found in Morocco. Ostrich 87: 73–76.

Abstract:

The Egyptian Vulture Neophron percnopterus population in Morocco has undergone a marked decline since the 1980s to the point of nearing local extinction in the twenty-first century. A field study of some possible sites for Egyptian Vultures was carried out over six days during June 2014 in the Middle Atlas Mountains, Morocco. We counted a total of 48 Egyptian Vultures at three different localities: two occupied breeding sites and one communal roost that hosted 40 vultures of different ages. A (probable) singe adult bird at the breeding site was located and a previously occupied site was also visited. A preliminary survey amongst local people indicated that threats faced by this species are predator poisoning in some areas, and the use of vulture parts for traditional medicine. Given that the species is considered globally Endangered and populations continue to decline in many areas, the discovered population reported here, although relatively small, is of national and regional (North-west Africa) importance. We expect this new situation will revive the hopes for studying and conserving this and other vulture species in Morocco and North-west Africa in general.

Breeding ecology of Turtle Doves (Streptopelia turtur) on intensively cultivated farmland

Hanane, S. (2016). Effects of location, orchard type, laying period and nest position on the reproductive performance of Turtle Doves (Streptopelia turtur) on intensively cultivated farmland. Avian Research 7: 4.  doi: 10.1186/s40657-016-0039-0 (Open Access)

Abstract

Background
Until recently little was known about factors affecting reproductive parameters of the Turtle Dove (Streptopelia turtur) on intensively cultivated farmland in the Mediterranean area. In this study, the reproductive parameters of this game species were evaluated in relation to location, orchard type, laying period and nest position in central Morocco.

Methods
A total of 317 nests were found and analyzed across five breeding seasons (2004–2008) in the Haouz and Tadla regions, over two major agro-ecosystems made up of olive and orange orchards. Nest position, laying period, clutch size and the number of chicks hatched and fledged per nest were determined on 120 study plots. I used Generalized Linear Models (GLMs) with a Poisson distribution and a log link function, including the logarithm of the number of eggs in each clutch as an offset to model the number of chicks hatched and fledged per nest.

Results
Clutch-size was not affected by location, orchard type, laying period or nest position. The number of chicks hatched per nest differed between orchard types; they were greater in olive orchards (1.33 ± 0.06) than in orange ones (1.03 ± 0.08), whereas the number of chicks fledged per nest consistently differed with laying period and orchard type, which were higher in the early laying period (1.22 ± 0.07) than in the late period (0.93 ± 0.08) and higher in olive orchards (1.22 ± 0.06) than in orange orchards (0.90 ± 0.06). Neither location nor nest position were related to variation in the fledging success of the Turtle Dove.

Conclusions
Olive orchards and the early laying period confer better nesting conditions than orange orchards and the late laying period. Although nest position could be different in each orchard type, it did not affect the breeding success of the Turtle Dove, suggesting that factors other than tree characteristics are influential. Further studies are needed to improve our understanding of the effects of anthropogenic disturbance, especially agricultural activities and hunting, on the productivity of Turtle Dove nests.

PDF in ResearchGate.net

Résumé:

Le marais de Fouarat représente l’une des zones humides de la région du Gharb. Il abrite une faune et une flore aussi importante l’une que l’autre et manifestement en perpétuels changements saisonniers. Dans le but de mettre cette zone en valeur, et de montrer son importance dans la biodiversité locale, régionale et nationale, nous avons entrepris d’étudier sa biodiversité aviaire, notamment celle de l’ordre des Ardéiformes et la phénologie des différentes espèces qui le composent, en mettant le point sur la nidification, l’hivernage et la migration pré – et postnuptiale des taxons en question.
Des notifications de présences et des recensements quasi hebdomadaires ont été réalisés durant l’année 2013, qui nous ont permis de dresser la liste de toutes les espèces d’Ardéiformes vivant dans le marais et d’avoir une idée sur les fluctuations de leurs effectifs saisonniers.
Nous avons rencontré lors de nos visites dix espèces d’Ardéiformes, à savoir : le Blongios nain (Ixobrychus minutus), le Bihoreau gris (Nycticorax nycticorax), le Héron garde-bœufs (Bubulcus ibis), le Crabier chevelu (Ardeola ralloides), l’Aigrette garzette (Egretta garzetta), la Grande Aigrette (Casmerodius albus), le Héron cendré (Ardea cinerea), le Héron pourpré (Ardea purpurea), l’Ibis falcinelle (Plegadis falcinellus) et la Spatule blanche (Platalea leucorodia).

Phenology of the Ardeiformes of Fouarat’s wetland of Kenitra (Morocco)

Abstract:

Fouarat’s swamp is one of the Gharb’s region wetlands. It represents a habitat for an important fauna and flora witch are clearly in perpetual seasonal changes. In order to enhance this area, and to show its importance in the local, regional and national biodiversity, we undertook to study its avian biodiversity, including that of the Ardéiformes order and its different species phenology, putting the accent on the nesting, wintering and migration pre – and post-nuptial of its taxa.
Notification of presence and almost weekly censuses were done in 2013, which allowed us to make a list of all the Ardeiformes species in the marsh and to have an idea about the seasonal fluctuations of theirs numbers.
During our visits, we met ten Ardéiformes species: Little Bittern (Ixobrychus minutus), Black-crowned Night Heron (Nycticorax nycticorax), Cattle Egret (Bubulcus ibis), Squacco Heron (Ardeola ralloides), Little Egret (Egretta garzetta), Great White Egret (Casmerodius albus), Grey Heron (Ardea cinerea), Purple Heron (Ardea purpurea), Glossy Ibis (Plegadis falcinellus) and Spoonbill (Platalea leucorodia).

Autumn-winter breeding by Cream-coloured Coursers Cursorius cursor is more common than previously reported

Amezian, M., Bergier, P. & Qninba, A. 2014. Autumn-winter breeding by Cream-coloured Coursers Cursorius cursor is more common than previously reported. Wader Study Group Bulletin 121: 177–180.

Abstract:

Until the end of the 20th century there were only limited numbers of autumn-winter breeding records of the Cream-coloured Courser Cursorius cursor. Here, we compile several autumn-winter breeding observations obtained mainly by amateur birders (citizen scientists) and we show that this phenomenon is more common when local conditions (especially rainfall) are favourable. These observations are from several parts of the species’ range, as far apart as Socotra Island (Yemen), Oman, and the Canary Islands (Spain), although the majority are from the region of Oued Ad-Deheb, southern Morocco.

Factors influencing species-richness of breeding waterbirds in Moroccan IBA and Ramsar wetlands

Cherkaoui, S. I., Hanane, S., Magri, N., El Agbani, M.-A. & Dakki, M. (2015). Factors influencing species-richness of breeding waterbirds in Moroccan IBA and Ramsar wetlands: a macroecological approach. Wetlands 35(5): 913–922.
doi: 10.1007/s13157-015-0682-y

Abstract:

Since 2005, Morocco has designated 28 Important Bird Areas (IBA) and Ramsar wetlands for waterbirds, yet little is known about how waterbird communities are changing over time and space, within and between sites. We assessed the relationships between species numbers of overall breeding waterbirds, as well as those of Anatidae, Rallidae and Podicipedidae, and geographical, topographical and macrohabitat factors. Species richness of overall waterbirds and Anatidae were positively correlated with: (i) extent of emergent vegetation, (ii) number of plant species present, and (iii) altitude. Species richness of Rallidae was positively correlated with: (i) latitude, and (ii) different beds of emergent vegetation, while that of Podicipedidae was exclusively correlated with altitude. These results suggest that breeding waterfowl are significantly related to habitat characteristics, most importantly vegetation structure, and altitude. Our findings give support to the idea that large mountain wetlands protected areas provide valuable habitat to breeding waterbirds in this region, by providing larger buffer zones with fewer human activities, such as hunting, urbanization and tourism disturbance. This study provides a platform from which we can advance the scientific research on Moroccan IBA and Ramsar wetlands.
