Thank you.

The first bird should be HP, ringed in Nov-2020 at Mai Po. This is the first sighting.

The bird with black over white flag was ringed in Shanghai Chongming Dongtan Nature Reserve. I have let the Reserve staff know about this sighting.

The last one DH was ringed in Nov-2021 at Mai Po, first sighting as well.
