Each year the Beijing Raptors Rescue Centre nurses back to health more than 300 injured birds that were rescued from the wild or turned in by their captors. More than 43 types of raptor can be found year-round, as the city is on their migratory route. Some end up caught in traps, while others are injured by vehicles or predators. The centre, run by the non-profit International Fund for Animal Welfare group, helps rehabilitate birds and prepares them for release back into the wild.
