The approach of the birds to use physical and alimentary resources in degraded and modified natural habitats is an important aspect of their adaptation. This study was undertaken during 2016-2017 at forty habitats in the Moulouya plain, Morocco to examine behavioral diet, habitat use and foraging ecology of turtle dove, . We monitored turtle doves in four major plots namely cereal plots, lucerne farms, apple orchards, and stations in the Ansgmir River covering 40 habitats. Digestive tract contents were also identified and evaluated for 68 Turtle Doves shot by hunters during two consecutive years. The results showed that the turtle doves use a variability of feeding habitats. The cereal cultivation seemed to be more preferable habitat for feeding especially in the month of May, the first breeding phase of the year. But, during the months of August and July, the riverbanks were the preferred habitat for turtle doves. The diet of this species is polyphagous and diverse with a granivorous tendency. Diet analysis showed that soft wheat and barley seeds constituted 44.53% and 38.74% respectively followed by barley seeds with 38.74% and sand stones (9.16%) of the seeds eaten by Turtle Doves. However, moderate proportion of elements (7.32%) remained undefined. All these aspects, including the variability of feeding habitats and the wide diet seem to be an adaptive strategy followed by turtle dove to counter the degradation and the modification of its natural feeding habitats.
鸟类在退化和改变后的自然栖息地中利用物理和食物资源的方式是其适应性的一个重要方面。本研究于2016 - 2017年在摩洛哥穆卢亚平原的40个栖息地进行,以研究斑鸠的行为性饮食、栖息地利用和觅食生态学。我们在四个主要区域监测斑鸠,即谷物种植区、苜蓿农场、苹果园以及安斯米尔河的站点,涵盖40个栖息地。还对连续两年被猎人射杀的68只斑鸠的消化道内容物进行了鉴定和评估。结果表明,斑鸠利用多种觅食栖息地。谷物种植区似乎是更适宜觅食的栖息地,尤其是在5月,即一年中的第一个繁殖期。但是,在7月和8月,河岸是斑鸠偏爱的栖息地。该物种的饮食具有多食性且多样,有食谷倾向。饮食分析表明,软质小麦和大麦种子分别占所食种子的44.53%和38.74%,其次是大麦种子占38.74%,还有沙石(9.16%)。然而,有中等比例(7.32%)的成分仍未明确。所有这些方面,包括觅食栖息地的多样性和广泛的饮食,似乎都是斑鸠为应对其自然觅食栖息地的退化和改变而采取的一种适应策略。
