SummaryBirds are suffering from steep population declines on a global scale and they are one of the few taxonomic groups for which these declines are well documented by long-term monitoring data. This study provides a synthesis of the status of the breeding birds of Greece. To this aim, we retrieved population size estimates from six sources spanning 22 years (1992–2014) and calculated species’ trends in Greece. Using the IUCN Red List assessments for each species we assessed whether ecological traits including habitat and diet preferences were associated with species’ trends and conservation status in Europe and determined major threats affecting birds in Greece. Moreover, we assessed the importance of Important Bird & Biodiversity Areas (IBAs) in terms of declining trigger species. Results showed that almost one fifth of the breeding birds in Greece have declining populations. Raptors were found to be the most threatened group of birds whereas the highest declines by dietary group were observed in scavengers, with 60% of species showing a decreasing trend. The most common threats were those that cause habitat alteration and degradation as well as more direct effects such as poisoning. Our results suggest that restoration of habitat and ecosystem functions along with the management of protected areas and improvement of legislation should be the main conservation actions undertaken and pinpointed the IBAs where they should be prioritized for implementation. Finally, further research, especially on specific drivers of population change, along with further examination of current and past population trends, will increase the power and accuracy of future regional Red List assessments especially concerning the breeding species for which the country bears the greatest responsibility.

希腊繁殖鸟类的状况：趋势、威胁和对保护的影响

摘要鸟类在全球范围内正遭受人口急剧下降的困扰，它们是为数不多的长期监测数据充分记录了这些下降的分类群之一。这项研究提供了希腊繁殖鸟类状况的综合。为此，我们从 22 年（1992-2014 年）的六个来源中检索了种群规模估计值，并计算了希腊物种的趋势。使用 IUCN 红色名录对每个物种的评估，我们评估了生态特征（包括栖息地和饮食偏好）是否与欧洲物种的趋势和保护状况相关，并确定了影响希腊鸟类的主要威胁。此外，我们评估了重要鸟类和生物多样性区域 (IBA) 在减少触发物种方面的重要性。结果表明，希腊近五分之一的繁殖鸟类的种群数量正在下降。猛禽被认为是最受威胁的鸟类群体，而在食腐动物中观察到的饮食组下降幅度最大，60％的物种呈现下降趋势。最常见的威胁是那些导致栖息地改变和退化以及中毒等更直接影响的威胁。我们的研究结果表明，栖息地和生态系统功能的恢复以及保护区的管理和立法的改进应该是采取的主要保护行动，并确定了 IBA 应该优先实施的地方。最后，进一步研究，特别是关于人口变化的具体驱动因素，以及对当前和过去人口趋势的进一步检查，
