Other foraging methods observed in this stork are prey herding mechanisms typical of other Mycteria species. One of these is foot stirring, whereby the stork stands on one leg and disturbs the river bed with the foot of the opposite leg; which may drive aquatic prey from places inaccessible to the storks. Milky storks also forage in flocks at high prey density, whereby they cooperatively flush fish in shallow water to divert them to their half-open bills; as has been observed in Java. Milky storks also often feed in aggregations alongside other wading bird species such as lesser adjutant and egrets. This stork occasionally detects aquatic prey by direct visual searching.
