Lesser
Coucal
Centropus bengalensis
Bubut Kecil, But-but (Malay)
Coucals feed on
large insects, frogs, lizards, snakes. They hunt these among the undergrowth,
using their powerful bills to catch and kill their prey.
Coucals are rather terrestrial, preferring to walk than fly. They
emerge in the open only in the early morning. The rest of the day,
they forage on foot in tall grass. When disturbed, they make a short
flight with shallow wing beats and brief glides into cover. They then
scuttle away on foot. They are strong runners and have straight hind
claws and are sometimes called "lark-heeled cuckoos".
Lesser Coucals are mostly solitary, only rarely seen in pairs. They
specialise in more open grasslands (lallang and other tall grasses)
both dry and marshy, while the Greater Coucals (C. sinensis)
are found in thickets.
Breeding: Lesser Coucals have
a courtship ritual of offering each other titbits like a leaf or grasshopper.
Although they are members of the cuckoo family, Lesser Coucals do
not lay their eggs in other birds' nests.
They build their own nests. These are usually well concealed and comprise
a large globe (18 x 25cm) made of twigs or grass (blades and stems)
with a large entrance hole to one side. The nest is sometimes lined
with green leaves and grass.

Juvenile
and non-breeding adult: head, neck and mantle brown
streaked with pale buff; rump and upper tail coverts,
blackish barred rufous; tail dark brown glossed with green;
underparts buffy with paler streaks.
Call: Described as a series
of mellow whoops; 3-4 hiccups followed by knocking rattles;
sharp 3-note call that sounds like got-to-go; or
boot-boot-boot, like their Malay name.
In flight: Low, rapid shallow
flapping with long spurts of gliding, seldom raising their
wings above the horizontal.
Similar birds: Greater Coucal
(C. sinensis): The Lesser is smaller, somewhat
paler and has chestnut wing-linings, while the Greater
has black wing-linings. Unlike the Greater, when in the
breeding the Lesser has pale buff streaking on nape and
upper back and appears more streaky and scruffy because
the Lesser has very glossy head feather shafts which reflect
the light and make them appear almost white.
Status in Singapore: Common
resident throughout the island and North offshore islands.
World distribution: India to East Indonesia.
Classification: Family Centropodidae.
World 30 species, Singapore 2 species. Order Cuculiformes
(Cuckoos). |

They build in open grasslands, close to the ground, incorporating
tall grass stems into the nest. Less frequently, low in bushes or
trees.
2-3 white eggs are laid in December-July. Hatchlings are black skinned
with long bristly down. Like other Coucals, when disturbed, the chicks
squirt out copious amounts of foul-smelling liquid faeces.
The Coucals have the head and bill of a crow, but long tail feathers
of a pheasant. In fact, in the past, they were known as crow-pheasants.

Argus
Argument
A
local folktale explains why the
Argus Pheasant is so beautifully marked
while the Coucal is so plain.
One day, both birds met and decided
to help each other disguise themselves
from their enemies with tattoos. The Coucal diligently marked the
Argus with fine and beautiful tattoos, but when it came to the Argus'
turn, it was too lazy and simply poured the tattoo ink over the
Coucal and ran away!!
|
Status
and threats: Lesser Coucals have adapted well to open grasslands
and secondary growths that result from human interference. They are often
the first to colonise a new patch of lallang and other wastelands. They
are not considered at risk in Singapore. In fact, they have become among
the most common of the cuckoo family in Singapore.
