In the last two outings to Po Toi, I realised that there were few HK residents at Po Toi. For example, Japanese White-eye seems to be totally absent, and the no. of Bulbuls are very low. Black-necked Starling, Masked Laughingthrush, Greater Coucal, Great Tit, Great Tit were not recorded and Crested Myna was seen briefly on last Sunday. The bird density is also very low. Then I realised that Peregrine Falcon were at the cliff of the South Peninsula, and a Crested Goshawk were around the main area. I wonder whether these two Raptors were responsible for the departure of the common residents.
