greenshanks & a murder @ SBWR - Nov2017

The crows had a few moments ago ganged up against the visiting whimbrels successfully causing them to flee for fear of being clawed at. This time it was the greenshanks' turn (and a hapless common sandpiper who thought the greenies were safe to hang around with). With the crows being repeatedly concentrated within the safe refuge of the wetland reserve due to the crow-culling team shooters regularly lingering outside the boundary of the protected wetland reserve, their numbers have increased to such a level that any species even remotely competitive would eventually be harassed away by the relentless murders of crows. This change in the avian dynamics within Singapore's only wetland reserve seems inevitable given the persistent crow culling just outside. The crows have also begun their taste experiments with organisms within the muddy mangrove substrate. No doubt they had plenty of opportunity to watch and learn from their shorebird cousins. This puts them in direct competition with the shorebirds which unfortunately have a much less aggressive disposition as compared to the average marauding murder of house crows. This perhaps explains why the crows harass the shorebirds.
