Thnak Geoff this is helpful.
I think the next area of expertise for HK birders to develop will be in deformities and types of wear on HK birds.
I understand the Records Committee will produce something on this issue in due course, but perhaps we need to arrange a talk from a vet who deals with cagebirds to understand the likely types of damage.
Its good to have your reports coming again on Friday mornings to get us all thinking about birding in the weekend ahad
Cheers
