I observed on two occasions when two Large-billed crows (Corvus macrorhynchos) attacked a Buffy fish- owl (Ketupa ketupu) nest at Pasir Ris park on 22 and 24 Mar 2024. I was able to witness about four attacks by the crows. I will be showing a composite of images from these two dates to show in sequence how these attacks happened. It is difficult to show a complete sequence of the attack from one sitting as it is very challenging to be at the right place at the right time. It is very hard to predict how the event will unfold as it may happen suddenly from any place.
Apparently, these crow attacks happened daily, more than once a day, as I found out from a bird photographer who came regularly and stayed from morning to evening. I suspect the crows were defending their territory because I have seen them in this vicinity on many occasions. This was the first time that I spotted a Buffy fish-owl nest in this location. According to this photographer, he had also seen Oriental Pied hornbills and even a long-tailed macaque threatening the owl nest which caused the female adult owl to defend the nest.
