Bitterns and Egrets

Bitterns and egrets belong to the Ardeidae (Heron) family, see Taxonomy note below. This page features photo essays of Bittern and Little egret behaviour together with an image gallery of other species depicting feeding, hunting and other behaviours.

Bittern and Egret Notes

Like most members of the heron family, bitterns adopt different postures: upright with the head and neck extended when startled or to look for food; erect (bittern posture) with the bill and neck vertical and crouched with the head and neck withdrawn.

Photos show a female in startled with stretched neck and puffed up feather posture. Bitterns are incredibly agile, a sequence of images show a male gripping palm stems, striking prey in the water and capturing a fish in its bill. An immature image shows agility in catching fish. A sequence of five images depicts preening, observing, poised ready to strike, caught fish in its bill and swallowing prey. A slider image on ‘Birds’ page features a bittern stretched almost horizontally while gripping palm fonds.

Yellow bitterns hunt fish, amphibians and insects. They are resident over a broad range of South East Asia, Indonesia, native in Singapore. They are sexually dimorphic; males that have uniform dull yellow above and buff below; females have a streaked brown crown, neck and breast. Immatures have significantly more streaking.

Schrenck’s bittern or Von Schrenck’s bittern hunts similar prey to the yellow bittern. I photographed this species in the Wetland Centre pond at Sungei Buloh in Singapore where it is a winter visitor.

Little Egret Behaviour

Little Egret Behaviour Notes

Little Egrets do not take up a classical heron static stance when hunting but flutter around over the water and in the water to stir up the mud, presumably to scare the fish. They also fly short distances and then pounce on prey, sometimes in less than a second or two. They also shade the water with their wings.

The gallery shows some of this behaviour, including one bird devouring a medium-sized fish.

Egret Behaviour

Egret Behaviour Notes

The gallery is an ecliptic mix of egret images. The first sequence shows an eastern cattle egret in Kakadu National Park perched on a feral water buffalo going from relaxed to classic stretched neck pose when prey is spotted. Other images show little blue heron foraging and capturing prey and snowy and not-so snowy egret at Orange Valley mudflats in Trinidad.

Mixed flock photos show great-white and snowy egrets at Caroni Swamp and little and great egrets flying at Sungei Buloh Wetland Reserve.
