“…103 species of passerine birds that nest in Algeria out of 214 species, represent almost half of the avifauna (48.1%), it is a general dominance throughout the Palearctic zone (Isenmann and Moali, 2000). Given climate change, agricultural extensions, the appearance of new wetlands, especially artificial etc., all these factors, as well as others, can influence the phenological categories of species, this is what they cited by Chedad et al (2020b) and confirmed in several species Chedad et al (2020 a,b;2021b, c) .…”

This study is an avifaunistic diversity assessment was carried out in the Merine forest, Sidi Bel Abbes (Northwest Algeria). During three years (2019-2021). The major objective of our investigation is to inventory avian species and to define their phenological categories. Among the important results is a record of, 71 species of bird, belonging to 17 orders and 28 families. The Passeriformes are the most noted with 43 species, distributed across 15 families, of which the Muscicapidae is the most represented with 10 species. The phenological categories indicates that the majority of this species are resident breeders (65 %), 21% are migrant breeders and 14% are passing visitors. Depending on trophic status, 32% are polyphagous, 27% insectivorous, 17% carnivorous, 15% granivorous and 8% omnivorous. In addition, we noted that, 31 species are protected by Flat 12-235 in Algeria, with one species (Falco naumanni) protected by the Ordinance 06-05. Internationally and one species protected according of the IUCN red list (Streptopelia turtur). The Merine forest is shelter to five species endemic to North Africa: Barbary Partridge (Alectoris barbara), Levaillant's Woodpecker (Picus vaillantii), Moussier's Redstart (Phoenicurus moussieri), Tristram's Warbler (Sylvia deserticola), African Blue Tit (Cyanistes teneriffae).

“…Contrary to these previous studies, our data reveal that Turtle Doves used Northwest African grounds as wintering sites. The observation of these birds from mid‐October to February between 2015 and 2022 in several sites is important evidence that these birds were adapted to these habitats and confirm the separate observations made by Chedad et al (2020), Mansouri et al (2022) in Algeria and Morocco, respectively.…”

“…Across the eight study years (2015–2022), 155 Turtle Doves were observed in different habitats of Northwest African ecosystems. Despite the wide range of literature on the wintering features of Turtle Doves (Boukhemza‐Zemmouri et al, 2008; Browne & Aebischer, 2003; Calderon et al, 2016; Eraud et al, 2013; Lormee et al, 2016; Marx et al, 2016), only one study has reported three wintering Turtle Doves in Northwest Africa, principally in Algeria (Chedad et al, 2020). In addition, with the use of satellite telemetry, decades of recovery data, and geolocators, (Eraud et al, 2013; Lormee et al, 2016) (Marx et al, 2016; Schumm et al, 2021) have localised with high precision the wintering areas of Turtle Doves in sub‐Sahara.…”

Timing of migration dates and detection of first wintering sites for the Turtle Dove in Northwest Africa

The identification of migration dates and wintering zones for migratory birds are key elements for the understanding of the Afro‐Palearctic migration system. From 2015 to 2022, a large‐scale survey of Turtle Doves Streptopelia turtur, a vulnerable species, was established in Northwest Africa, including Morocco, Algeria, and Tunisia. We monitored migration dates and wintering individuals using the line‐transect method. We found that Turtle Doves arrived in the last week of March and left the North African region in mid‐October. Compared with Morocco, Doves arrived significantly earlier in Algeria and Tunisia. Moreover, Doves were discovered wintering on nine Northwest African sites, from October to February, where individuals feed in groups. We found that the occurrence probability of wintering Turtle Doves decreased significantly with increasing temperature and rainfall. Birds wintered most often close to wetlands since the overwintering probability decreased with the increasing distance from the recording area to the nearest water body. These are the first and only detailed findings on the migration phenology of the globally vulnerable Turtle Dove in north western Africa.

“…It winters in Africa mainly in the Sahel zone with new attempts recorded currently in North Africa ( Schumm et al, 2021 ; Mansouri et al, 2022a ). Four subspecies are recognized: S. t. turtur (Europe, S and N Mediterranean coast, Asia Minor to W Siberia) ( del Hoyo et al, 2014 ; Marx, Korner-Nievergelt & Quillfeldt, 2016 ); S. t. arenicola (Morocco to Tripolis) ( El Hassani, Dakki & El Ghadraoui, 2018 ); from Iraq, Iran, Afghanistan to W China ( Abode et al, 2021 ); S. t. hoggara (Ahaggar, Tibesti, Ennedi Massifs in Sahara ( Chedad, Bendjoudi & Guezoul, 2020 ) and S. t. rufescens (Kufra Oasis, Dakla, Kharga and Faiyum oases, Nile valley) ( Dubois, 2002 ; Prakas et al, 2021 ).…”

Background The turtle dove is a migratory species that has suffered a rapid decline principally across its Northern ranges, despite pronounced conservation measures. Consequently, it has been categorized as ‘Near Threatened’ in Europe. Degradation of breeding habitats and a decrease in food resources are listed as principal causes of this decline. Despite its importance, the productivity of the North African population is widely unknown. Here we present the first estimation of the density of the breeding population and the superior reproductively of Streptopelia turtur arenicola in Morocco and entire North Africa. Methods This study was carried out for two seasons 2018–2019 in the Saïss plain, central Morocco. Based on previous data, doves were monitored weekly, from early March to late August, in aquatic ecosystems (two dams and one river) and farmlands (cereals and orchards). The breeding population was censused using the “point-count” method, following a walked transect of 5 km in orchards, 7 km in cereal fields, and 3 km along the river. Equally, nests were searched in natural habitats counting riparian trees, forests, and ornamental trees, and in orchards based on the Common Birds Census (CBC) methodology, in which the singing doves, mating pairs, nesting, and/or feeding behavior were the most monitored signs to discover nests. In orchards, nests were searched line-by-line based on the rows of fruit trees. For each recorded nest, we note the breeding chronology, clutch size and incubation period, success and failure factors, dimensions, and vertical placement on trees. To evaluate the predictors of doves’ occurrence, we noted at each site the presence of cereals, water, human disturbance, presence of nesting trees, and predators. Results and Discussion In total, 3,580 turtle doves (22.37 birds/ha), including 240 breeding pairs, were documented. Nesting occurred mainly in olive groves, cereals were used for forage, and aquatic ecosystems for water sources. The nesting period lasted from late April to July (last fledglings). All nests were located on olive trees at a height of 225.30 ± 48.87 cm. The clutch size was 1.98 ± 0.13 (laid eggs/built nests), the incubation period lasted 14.16 ± 1.32 days, and the rearing period lasted 16.54 ± 1.76 days. The breeding success among the 240 monitored nests accounted for 73.84% during the nesting phase and 87.42% during the incubation phase; 71.5%% of nestlings have fledged, which is the highest success rate for turtle doves in Europe and Northwest Africa. Clutches were aborted mostly due to predation from snakes (7.5% of nests, 16.12% of eggs, and 5.63% of chicks), nest desertion (9.16% of nests and 5.37% of eggs), and marginally by the destruction of nests through farming activities. These findings are important for conservation plans, to restore turtle doves’ habitats in Europe, where the species is widely declining.
