For migratory birds, sustainable harvest management based on quantitative modelling needs cross-border hunting bag statistics. At the European scale, proper modelling requires both reliable and mutually compatible hunting bag data between regions and countries. Owing to the absence of harmonisation among the different hunting bag collecting schemes in Europe and the lack of methodological metadata, adaptive management at the flyway scale is currently extremely challenging for a number of species. For improving the current state of affairs, we expose statistical concepts, terminology and issues inherent to hunting bag data collection schemes; identify the multiplicity of error sources for being able to judge the quality of hunting bag statistics; call for a harmonisation process; discuss the origin of the hurdles in the production of standardised hunting bag statistics at the European scale; and suggest some potential avenues for future actions for overcoming them.

从意图转向采取行动来收集欧洲范围内的狩猎包统计信息：一些方法学见解

对于候鸟，基于定量建模的可持续收获管理需要跨境狩猎包统计。在欧洲范围内，正确的建模需要区域和国家之间可靠且相互兼容的狩猎包数据。由于欧洲不同的狩猎袋收集计划之间缺乏统一性，并且缺乏方法学上的元数据，对于许多物种而言，在飞行道规模上进行适应性管理目前极具挑战性。为了改善当前的状况，我们介绍了统计概念，术语和狩猎袋数据收集方案固有的问题；确定错误源的多样性，以便能够判断狩猎袋统计数据的质量；呼吁协调进程；讨论在欧洲范围内制作标准化狩猎包统计数据时遇到的障碍；并为将来的行动建议一些可能的途径。
