Raptor and sparse grassland bird species represented by the migration concentration models, migration time periods for each species, and the numbers of observations used from existing occurrence datasets for model validation.

Raptor and sparse grassland bird species represented by the migration concentration models, migration time periods for each species, and the numbers of observations used from existing occurrence datasets for model validation.本数据集包含以迁徙聚集模型（migration concentration models）表征的猛禽（Raptor）与稀树草原鸟类物种、各物种的迁徙时段，以及从现有物种出现数据集（occurrence datasets）中提取的用于模型验证（model validation）的观测样本量。
