The analysis of biological diversity at a regional scale is the first step to understand and classify the biological importance of a specific region and therefore the adoption of implementing conservation strategies. We conducted weekly bird counts by using the point count method from January 2015 to December 2017 in Midelt province, Morocco. A total of 130 bird species were observed, among breeding, migrant, and wintering species belonging to 42 families. Accipitridae (15 species), Muscicapidae (9 species), and Alaudidae (9 species) were the most observed families. Order of Passeriformes was the dominant order represented with 16 families and 68 species. Moreover, five species of conservation concern were recorded such as the vulnerable European turtle dove, houbara bustard, and Dupont’s lark; the near threatened ferruginous duck and bearded vulture; and the endangered Egyptian vulture. On the other hand, the results of the diversity analysis (Margalef index, Shannon–Wiener index, and Simpson index) showed the highest diversity in wetlands, forests, steppes, and farmlands, while cliff, landfills, and urban areas were the least diversified habitats. Finally, with its geographic situation between humid Atlas and Sahara desert, as well as the diversity of habitats and avifauna, Midelt region needs advanced analysis in terms of biodiversity and environmental characteristics, in order to provide effective conservation management.
The European Blackbird (Turdus merula) is a widespread species. In Morocco, available knowledge on this species is limited to a few descriptive pieces of information with no detailed data provided. With climate change and the intensification of agricultural activities, the study of the breeding performances of this species is indispensable for management purposes. This study investigates breeding biology, nesting habitats, breeding chronology, and reproductive success of the European Blackbird in both apple orchards and surrounding woody vegetation at Ait Ayach (Morocco) between March and August 2016. We monitored weekly nest status, nesting sites, breeding dates, and failure factors. Results showed that the European Blackbird nests mainly in apple orchards, on Golden Delicious and Starkrimson Delicious trees. Nest height above the ground was 214.15 ± 0.09 cm. Blackbird nests were cup-shaped with medium size dimensions and built from twigs, including dry leaves, stems, and roots walled by the mud. Breeding activities started firstly by nest construction during the last week of April, secondly by egg laying during the first week of May, and thirdly by hatching during the second week of May. Among the 74 surveyed nests, 100% were active during the nesting phase and 88.38% of eggs have succeeded during the incubation phase. In total, 69.03% of chicks have been emancipated. In short, 15.9% of clutches were attacked by predators, 14.35% of clutches were failed due to nest desertion, and 8.75% of chicks were dead. Our study provides the first and only detailed data on reproductive parameters of the European Blackbird in Moroccan ecosystems. Data collected from this study provide valuable information for long-term monitoring of the Moroccan Blackbird population. Additionally, our data offer a possibility of large-scale comparative studies of the reproductive ecology of the Blackbird species.
The European serin (Serinus serinus) is one of the best examples of a species in the western Palaearctic that has expanded its distribution ranges in current periods. However, the breeding features of serin are not well known and were restricted for some localities, as well as there have not been any deep and comparable studies on its mortality and menacing factors. This study investigates breeding biology, including breeding chronology, nesting strategies, and reproductive success of the European serin in farmland and woodland habitats at Moulouya high plain (Morocco), during 2016. Results showed that, at high-altitude breeding habitats, the European serin started breeding activity lately by 25 April (construction of the first nest) and continued until 19 July (last fledging date). Moreover, most nests (96.42%) were found in farmlands, mainly in apple orchards. Two broods were recorded between April-May and June-July, and the clutch size was an average of 3.04 ± 0.13 eggs/nest. For reproductive success, among the 65 examined nests, 73.84% were active during the nest construction phase and 87.42% of eggs have succeeded during the incubation phase. Reproductive success was higher (93.83%) during fledging. Clutches were failed due to predation (15.9%), nest desertion (14.35%), and destruction of nests (8.88%). Finally, our study highlights that the European serin breeds in high-altitude zones with late and shorter breeding seasons, which might allow this bird to avoid high lands’ vigorous climate conditions and their effect on breeding success.
The current study aimed to investigate the nesting behavior and breeding chronology of the crested coot (Fulica cristata) in Morocco's high altitude wetlands. We monitored nesting activities and breeding phenology in two wetlands, Zerrouka and Hachlaf lakes, to achieve our goals. Besides, nesting materials and nest dimensions were analyzed to characterize the crested coot nests. As a result, 52 nests were found in two sites, 18 in Zerouka and 34 in Hachlaf. Nests were built by available twigs on each site, and nest dimensions varied between analyzed wetlands. Nests were larger in Zerrouka compared to Hachlaf Lake. To protect their nests, coots select open waters and submerged vegetation as nesting sites. On the other hand, breeding chronology, including nesting, laying, and hatching dates, was earlier in Zerrouka Lake than Hachlaf. The nesting activities started at Zerrouka during January and February, while at Hachlaf, breeding attempts started during April.
