Each year at this time, Guanting Reservoir becomes a hub for birds travelling southward. As one of the world's eight major migratory routes for birds, Beijing plays host to millions of birds migrating each spring and fall. These feathered travelers arrive in droves, feasting and resting before resuming their journey.

This year presents a slight deviation from the norm at the reservoir. A drop in water levels has expanded the mudflat area, attracting more wading birds to feed. Consequently, there's been a notable increase in the crane population compared to previous years.
