These are presumably two different birds, one at KFBG and another in Lam Tsuen. If anyone has more photos, I would urge you to post them or to contact me by PM. I will try to establish the individuals involved.
The KFBG bird appears to include -38- in the ring number. This might indicate a new longevity record for the species. Any photos showing more of the ring number would be very useful.
The Lam Tsuen bird has, I suspect, come from KFBG. This would be the first confirmed movement of this species. Again, if anyone can provide some or all of the ring number, it would be very useful. It looks like the bird may be nesting, in which case it may be possible to get a good view (but please DO NOT disturb the nest!)
Please note that it is always useful to post pictures of ringed birds, especially if the ring number can be read. Alternatively, PM me with details of a ring. For some species (especially prinias, white-eyes and bulbuls) it may be difficult to be certain of the individual involved. For others, it may be possible to work this out from a partial ring number or location. I understand that most photographers take great pride in getting such good photos, but remember that the crucial information on a ring may be obtained even when the photo is not perfect (for example if the bird is partly obscured). If you are able to photograph a ringed bird, please try to get photos from as many angles as possible (to maximise the number of digits seen).
In HK, photographs of ringed birds have provided information on the migration of Japanese Yellow Bunting (the bird ringed in Japan and photographed on Po Toi), the local movement of White-shouldered Starlings (from colour-ringed birds) and a longevity record for (at least) Long-tailed Shrike. It seems that photographers may have an important role in future with obtaining information about ringed birds.
