The global population was previously estimated to number 44,000-57,000 individuals. This species has suffered rapid population reductions across most of its range owing to the loss, degradation, and fragmentation of its habitat, as well as hunting. Key threats are increased habitat degradation, fragmentation, and loss due to agricultural intensification, land-use changes, and infrastructure development. Collisions with power lines are a serious threat for the species (Janss & Ferrer 2000, Raab et al. 2010), in some countries (e.g. Slovakia) this factor even contributed to the rapid decline and extinction of local populations.
