Little
Egret
Egretta garzetta
Bangau Kecil (Malay)
The Little Egret is the smallest and most common egret in Singapore.
Singapore receives a good concentration of these migrants during the
winter (September-May).
In February, just before they leave for their summer breeding sites,
some may start to put on their beautiful breeding plumes (right).
Little
Egrets eat a wide variety of prey from fish, molluscs and worms to
insects and even small mammals and birds.
Little Egrets are the liveliest hunters among herons and egrets, with
a wide variety of techniques. They may patiently stalk prey in shallow
waters. Or stand on one leg and stir the mud with the other to scare
up prey. Or better yet, stand on one leg and wave the other bright
yellow foot over the water surface to lure aquatic prey into range.

including North offshore islands. The race nigripes

In peninsular Malaysia, some have been observed hunting near floating vegetation
(like palm fronds), possibly looking for prey attracted to the shade. They
may crouch with their wings slightly outstretched, either to reduce the
sun's glare or perhaps to create shade to attract underwater prey. They
may also enthusiastically rush around in shallow waters perhaps to flush
out prey. Little Egrets usually hunt alone. Where they hunt in a group,
they are well spaced out, each individual aggressively defending a feeding
spot. However, they roost communally, often with other herons and egrets,
usually in mangroves. They also roost in reedbeds or snags over open water.
Breeding:
Little Egrets breed in the warm-temperate areas of the Old World, as well
as tropical areas like Java, Bali and Kalimantan. But they are not known
to breed in Singapore. They build rough nests out of sticks. A wide variety
of nesting sites are used, from trees and bushes to rocks, walls and even
on the ground. Up to 5 greenish-blue eggs are laid.
Migration: Little Egrets spend
winter in Southeast Asia, migrating in large dispersal flocks, arriving
mainly in September-October. Their preferred wintering grounds are mangroves
where there are mudflats suited to their hunting style and providing preferred
roosting sites. In Singapore, they are mostly found in estuaries, mudflats,
ponds, mangroves and even canals. Some may stay in their wintering grounds
over the summer.
Status and threats: Like other egrets
with beautiful breeding plumes, Little Egrets were threatened by hunting
for their feathers (for more, see our page on the family Ardeidae).
Now, they are more threatened by habitat destruction and pollution. The
overuse of pesticides have made them scarce in rice fields.
