Dear tomatofamily,
Being a HKBWS member, I think you would agree to follow the "Code of Conduct for Birdwatching and Photography announced by HKBWS:
http://www.hkbws.org.hk/BBS/view ... &extra=page%3D1
In order to protect bird nest and juvenile, bird watchers and photographers are NOT encouraged to approach bird nest and chick and juvenile birds. I know you may encounter this chick during your visit and you do not mean to disturb it. However, from your reply above, especially the sentence "See, when we look at this issue in a macro way, I would not worry about our behaviour, i.e. walk closer to have a look or take a nice photo of the babies and the juveniles.", I think this would mislead other members in this forum that human approaching nests and chicks is an acceptable behaviour.
We would like to clarify that HKBWS do not encourage people to approach breeding birds, nests, eggs, chicks and juvenile birds so as to minimize human disturbance to them.
Vicky
HKBWS Officer
