Thank you very much.
The first bird is D7. It was ringed on 15-Nov-2023 and fitted with a GPS tracker. This is the first sighting. Since the tracker did not transmit any signal, I thought the bird is not alive! Great to know that it is still around.
The second bird is CV. It was ringed on 11-Apr-2021. It was recorded at Mai Po every year in April.
