A fellow birder of the loca (Chilean) watchers net informed us about death of Peruvian diving petrels (Pelecanoides garnotii), an endangered species according to UICN, at a coast town in Central Chile, apparently due to dazzling caused by recently changed luminaries, the new ones being higher both in size and intensity.
We have already contacted relevant local authorities as well as some biologists who have provided information on the species, but locally we seem to have very little experience and technical directives ruling public illumination, so my question is:
Does anybody know of internationally acknowledged standards or directives on the subject, giving e.g. sound, practical advice on light intensities, projection angle, suitable distance from the coast and further parameters that can help us solve the problem?
Any information provided will be highly appreciated.
