Breeding biology of sympatric LaughingStreptopelia senegalensisand TurtleStreptopelia turturDove: a comparative study in northeast Algeria

Abstract

The Turtle Dove and Laughing Dove display distinct behavior and are morphologically and genetically different. However, microhabitat selection and reproductive success details of the two species are still poorly studied. The geographic distribution of the Laughing Dove in North Africa has clearly expanded nowadays. The breeding ecology and nest placement of this species have been studied previously, but little is currently known about its life history in Algeria. This study aimed to provide the basic information on the breeding biology of the Laughing Dove in Algeria. During two consecutive breeding seasons (2013-2014), the clutch size, brood size, chick survival, timing of breeding, densities of breeding pairs, nest placement, and the main causes of nest failure of the sympatric Laughing Dove and Turtle Dove were studied in an olive orchard in Guelma region, northeast Algeria. Clutch size, brood size, chick survival, the estimated productivity, and nest placement of the two species were similar but timing of breeding and population densities were significantly different. Finally, the largely coincident egg-laying period and the similar clutch size of the two species seem to be the main factors behind their similar survival rate and productivity in our study area.Paprastieji ir mažieji purpleliai skiriasi morfologiškai, genetiškai ir elgesiu. Šių rūšių veisimosi sėkmė ir mikrobuveinių pasirinkimas ištirti nepakankamai. Apie mažojo purplelio biologiją ir ekologiją Alžyre žinių trūksta, nors rūšies geografinis paplitimas Šiaurės Afrikoje plečiasi. Tyrimo tikslas -apibendrinti informaciją apie mažojo purplelio perėjimo biologiją Alžyre. Guelmo regione (Šiaurės Rytų Alžyras) 2013-2014 metų perėjimo sezonų metu alyvmedžių sode buvo tirti simpatriškai gyvenančių mažųjų ir paprastųjų purplelių dėties ir vados dydžiai, jauniklių išgyvenamumas, perėjimo laikas, perinčių porų tankumas, lizdų vietos pasirinkimas ir nesėkmingo perėjimo priežastys. Dėties ir vados dydžiai, jauniklių išgyvenamumas, vislumas ir lizdaviečių pasirinkimas buvo panašūs, tačiau perėjimo laikas ir populiacijos tankumas reikšmingai skyrėsi. Panašų šių paukščių rūšių išgyvenamumą ir vislumą tirtame regione veikiausiai nulemia sutampantis kiaušinių dėjimo laikas ir panašus dėties dydis.

Drivers of nest survival rate in a southern Tunisian population of Laughing Doves (Spilopelia senegalensis)

“…Our results showed that the estimated daily survival rate of Laughing Dove nests in the studied oasis was similar to those previously estimated (Boukhriss and Selmi 2018). It was also equal to that reported for the same dove species by Brahmia et al (2015) in an agricultural landscape in northern Algeria (0.975). We also found that vegetation structure in the close nest tree environment and nest age provided important predictors of daily nest survival rate in the studied Laughing Dove population, whereas neither nest height nor laying date showed significant effects.…”

New Data on Migration Time, Breeding Phenology, and Breeding Success of European Turtle Doves in Their Highest Breeding Habitats in North Africa

“…Equally, departure dates (date of last observed birds in the breeding site) were recorded at the leaving of the last birds from the whole breeding area. After the installation of doves in the designated sites (after the arrival of breeding pairs), the nest initiation (first nest recorded after the arrival date), laying date (first egg after the nest initiation), hatching (first fledged chick), and chicks' nest leaving (first chick to leave its nest) were surveyed with three visits per month (each visit with three days in field), based on turtle dove breeding biology reported in North Africa [30,31,41,42]: (i) the first visit was conducted at the beginning of every month, (ii) the second visit from 10 th to 20 th days, (iii) the third visit from 20 th to 30 th days. Common Bird Census (CBC) methodology [36], instigated to provide sound and observational information on farmland bird populations in agricultural lands, was used and research took place from 06.00 to 18.00 hours.…”

“…Although the breeding ecology and migration dates of turtle doves have been examined in detail [28,29], there has been no comparable examination of the detailed breeding chronology and reproductive success in high-altitude habitats [22]. In all previous studies, research concerning breeding ecology was limited to an altitude ranging from 100 to 600 m in both Europe and North Africa [22,23,[30][31][32][33][34][35][36][37]. erefore, understanding the migration and breeding phenology at high-altitude habitat will open a new window in conservation measures, in particular with recent evidence indicating that turtle doves breed and feed in mountainous zones [22,23].…”
