Every year in winter, a flock of crows haunts the citizens of southern Gyeonggi Province, complaining of great inconvenience.



The Ministry of Environment is even accepting photo reports from citizens to determine the migration path of the flock.



This is a video uploaded to social media last month under the title 'Sky Status in Osan City'.



The sky is covered with countless crows, and flocks of crows are sitting in rows on power lines.



Online, there are a series of posts complaining of inconvenience about crows that have appeared not only in Osan, but also in Suwon, Hwaseong, and Pyeongtaek in southern Gyeonggi Province.



It's scary, and the streets are dirty with excrement.



It is estimated that the flock of crows haunting the southern part of Gyeonggi-do came from Siberia to spend the winter.



If you take a picture of a crow that appeared in Suwon, Hwaseong, and Ansan and upload it to the application 'Cada', 500 won is paid per photo.



It is said that they plan to produce a map of the appearance of rooks using the accumulated data.
