Stunning photos!
Further to Captain's comments, Bearded Reedling (=Bearded Parrotbill) is also now on Category E of the HK list on the basis of birds seen/trapped at Mai Po. (That was a thrill, walking to a net at Mai Po to find such a distinctive bird trapped!)
Unfortunately I think Purple Cochoa will have the same fate - Category E - but well done finding and identifying the bird
