Statistics show that there were seven days over the period when the volunteers observed more than 100 predatory birds. Red-footed falcons, Falco subbuteos, Japanese sparrowhawks, and crested honey buzzards were the main predatory bird species that stopped over during their migration.
A peak migration of red-footed falcons occurred this year. From Oct 25, swarms of the wildlife species were found foraging on the city's Guanzhang Mountain and Junzhang Mountain and in Hongsha Bay.

They would fly in flocks at daytime and rest on high-voltage lines at night. A combined 2,598 red-footed falcons have been spotted by local bird watchers this year.
Black bazas were also found hovering in flocks for a long time in Yixing, which is the first time that this predatory bird species has ever been spotted in the city.
