Very interesting. I reported 4 cormorants flying around / on the water below our house in Sai Kung a few days ago (Feb 3rd). I guess this sighting would be just the other side of the hills. Maybe they are regular and I just miss them but I hadn't seen them before and they did not stay long. We look out over Tai chau, Lap sap chau, & Yeung chau. I wish I had scoped them now but I was busy working :-(
