Thank you John.
DV was ringed on 31-Mar-2017. Reported in Apr-17, Apr-19, Apr-21 for 6 times at Mai Po or Shenzhen Futian. Good to see it returns again.
HN was ringed on 3-Apr-2022. This is the 1st sighting.
EY has a nice history: also ringed on 31-Mar-2017. Reported at Tianjin in May-2018, back at Deep Bay Apr-19 and Mar-2020. Great to have another sighting of it after 3 years!
