“…The black-necked grebe has a highly dispersed characteristic in the western side of North Africa. Cherkaoui, Bouajaja, Elbanak, Lahrouz, Hanane (2013) reported an expending breeding behaviour of this species in the middle Atlas (Morocco) since 2009. Dayet El Ferd due to its vicinity to the middle Atlas was frequented from 2017 by breeding pairs of black-necked grebes.…”

“…But, the black-necked grebe Podiceps nigricollis is rare in Eastern and Central wetlands of Algeria, but most common in the western region (Bendahmane, Mostefai, Moulai-Melliani, Houhamdi, 2014). This ascertainment is probably due to the neighbouring Moroccan wetlands from Dayet El Ferd (Moroccan population) (Cherkaoui, Bouajaja, Elbanak, Lahrouz, Hanane, 2013). The little grebe occupies a wide spectrum of habitats across its range (Athamnia et al, 2015).…”

“…The great crested grebe has a widespread distribution occupying most of Europe, Central and South Asia, and North Africa (Abdellioui, Bensouilah, Houhamdi, 2015). The black-necked grebe has a broad distribution from Western Palearctic to North America (Cherkaoui, Bouajaja, Elbanak, Lahrouz, Hanane, 2013).…”

In this current study, we examine the abundances and breeding phenology of three sympatric grebes (little, great crested and black-necked grebes) in Dayet El Ferd. These grebes were observed during all the period (2011-2018) in this wetland, except in September when the great crested grebe leaves the region. The abundances of these three grebes show a significant difference. In 2017, the total number of 71 nests was measured. The mean clutch size was 5.23 ± 1.49 eggs per nest. The highest number of eggs per nest was ten eggs, and most nests contained three eggs (N=18).

“…Each wetland was visited 4 times, and during each visit the observer (I. Cherkaoui) recorded the presence/absence of breeding duck species in 3-6 points (depending on wetland size), using a spotting scope (30X by 60 mm) and a telescope (60X). The range of duck observation varied from 20 to 400 m. Proofs of breeding for each species was confirmed by one of the following: (i) nest construction activity; (ii) presence of active nest; (iii) nest attendance by adults and (iv) presence of chicks nearby the adults or the behavioural breeding criteria (Cherkaoui et al 2014) and (v) copulation. The Ruddy Shelduck Tadorna ferruginea is a cavity-nesting duck (The´venot et al 2003) so criteria (i), (ii) and (iii) were not appropriate for this species.…”

Conservation of Anatidae in North Africa is hindered by lack of information concerning population size, population trends, and species‐habitat relationships. In this work, we used a 2‐year survey data in 25 wetlands distributed throughout Morocco to model duck spatial distribution and to assess the relevance of a set of environmental and anthropogenic factors in predicting site occupancy, by means of Generalized Linear Mixed Models (GLMM). Mallards and Ferruginous ducks were the most commonly detected species, whereas White‐Headed Ducks and Common Pochards were the least detected ones. An inter‐annual variation in site occupancy was recorded for Ruddy Shelducks, Red‐Crested Pochards and White‐Headed Ducks. Geographical location (measured mainly as distance to the coastline and altitude) was the major predictor of the occurrence probability of Ruddy Shelducks, Marbled Teals and Red‐Crested Pochards, while human presence and habitat features were the most relevant factors in shaping Mallard's distribution. However, none of the considered environmental and anthropogenic factors explained the distribution patterns of the Ferruginous Duck, Common Pochard and Gadwall. The results of this study clearly show that there are still gaps in our knowledge on factors driving wetland occupancy by breeding Anatidae in Morocco. The pursuit of the investigations, while considering other explanatory factors such as water quality (limnological data), diet, predation, and conservation status, is of great importance to more profoundly understand the dynamics of Moroccan duck populations.

“…In North Africa, the Black-necked Grebe is present in Algeria (Isenmann and Moali 2000), Morocco (Thévenot, Vernon, and Bergier 2003;Cherkaoui et al 2014) and Tunisia (Isenmann et al 2005). In Algeria, the species is more abundant in winter, particularly at the El Kala's wetlands, at Lake Oubeïra where up to 850 were censured in 1971-1979(van Dijk and Ledant 1983, in the eastern Oran region where 162 individuals were seen at Lake Gharabas (Metzmacher 1979), and at the sea.…”

In order to evaluate the number of Podicipedidae and to monitor their diurnal behaviour for the first time in North Africa, bimonthly outings were conducted from September 2013 to August 2014 in Garaet Hadj-Tahar, a Ramsar site. The population size varied significantly between three investigated species. The peak numbers observed during the whole study period were 484 and 86 individuals of the Little Grebe and the Great Crested Grebe, respectively. These two species were present all year. The maximum for the Black-necked Grebe was 13 individuals observed during January 2014. This last species was a rare winter visitor to Garaet Hadj-Tahar. The analysis of the diurnal time budget revealed that feeding was the major activity of the Little Grebe and swimming was the major activity of the Great Crested Grebe. The latter devoted more time to preening, resting and parading than the former did. The total time spent for agonistic behaviour and flight accounted for a minimal budget for both species. Pirmą kartą Šiaurės Afrikoje, Garaet Hadj-Tahar pelkių komplekse (Ramsaro konvencijos saugomoje teritorijoje) buvo įvertintas Podicipedidae šeimos paukščių gausumas ir elgsena dienos metu. Tyrimai atlikti kas du mėnesiai stebint šiuos paukščius 2013 m. rugsėjį -2014 m. rugpjūtį. Nustatyti ženklūs tiriamų rūšių populiacijų dydžių skirtumai. Mažieji kragai (daugiausiai -484 individai) ir ausuotieji kragai (86 individai) buvo aptinkami pelkėse per visus metus. Didžiausias juodakaklių kragų skaičius (13 paukščių) užfiksuotas 2014 m. sausio mėn. Į Garaet Hadj-Tahar pelkes juodakakliai kragai žiemojimui užklysta retai. Dieninės elgsenos stebėjimai parodė, kad mažieji kragai daugiausia laiko maitinosi, ausuotieji kragai -plaukiojo. Mažieji kragai daugiau laiko nei ausuotieji kragai skyrė plunksnų valymui, poilsiui ir ritualinei elgsenai. Mažiausiai abiejų rūšių paukščių laiko užėmė agonistinė elgsena ir skraidymas.
