Thank you for the records!
M4 is a nice one. It was ringed at Mai Po in Nov-18, stayed for winter until Apr-2019, came back to Mai Po in Sep-19 for the winter. M4 was reported in Mongolia this spring, probably breed there. Very nice to see it back!
BP was ringed in Jan-19 as a 2nd year bird (born in summer 2018). It was last reported on 15-Mar-20. This is probably its first journey back from the breeding ground.
Z4 and BE were just ringed on 20-Sep-20, both 1st year bird.
