    Approximate distribution of the Baya Weaver

    The Baya Weaver(Ploceus philippinus) is aweaverbird found across Southand Southeast Asia. Flocks of

    these birds are found in grasslands, cultivated areas, scrub and secondary growth and they are best known for

    their hanging retort shaped nests woven from leaves. These nest colonies are usually found on thorny trees or

    palm fronds and the nests are often built near water or hanging over water where predators cannot reach

    easily. They are widespread and common within their range but are prone to local, seasonal movements mainly

    in response to rain and food availability.

    Male ofburmanicus race with the bright yellow crown

    Among the population variations, three subspecies are recognized. The nominate racephilippinus is found

    through much of mainland India while burmanicus is found eastwards into Southeast Asia. The population insouthwest India is darker above and referred to as subspecies travancoreensis.[2]

    Female (burmanicus race) feeding juvenile in Kolkata, West Bengal, India.

    These are sparrow-sized (15 cm) and in their non-breeding plumage, both males and females resemble

    female house sparrows. They have a stout conical bill and a short square tail. Non-breeding males and females

    look alike, dark brown streaked fulvous buff above, plain (unstreaked) whitish fulvous below, eyebrow long and

    buff coloured, bill is horn coloured and no mask. Breeding males have a bright yellow crown, dark brown mask,

    blackish brown bill, upper parts are dark brown streaked with yellow, with a yellow breast and cream buff

    below.[3][4]

    [edit]Behaviour and ecology

    A flock in Hyderabad, India.

    Baya Weavers are social and gregarious birds. They forage in flocks for seeds, both on the plants and on the

    ground. Flocks fly in close formations, often performing complicated manoeuvres. They are known to glean

    paddy and other grain in harvested fields, and occasionally damage ripening crops and are therefore

    sometimes considered as pests.[5] They roost in reed-beds bordering waterbodies. They depend on wild

    grasses such as Guinea Grass (Panicum maximum) as well as crops likerice for both their food (feeding on

    seedlings in the germination stage as well as on early stages of grain[6]) and nesting material. They also feed

    on insects (including butterflies[7]), sometimes taking small frogs[8] and molluscs, especially to feed their young.

    [9] Their seasonal movements are governed by food availability. Their calls are a continuous chit-

    chit-... sometimes ending in a wheezy cheee-eee-ee that is produced by males in a chorus. A lower intensity

    call is produced in the non-breeding season. [10]

    They are occasionally known to descend to the ground and indulge in dust bathing. [11]

    In captivity, individuals are known to form stablepeck orders.[12]

    [edit]Breeding

    The breeding season of the Baya Weavers is during the monsoons.[2] The breeding condition is initiated by

    environmental characters such as day length and comes to an end after summer although this termination is

    not influenced by short day length as in temperate birds. [13]They nest in colonies typically of up to 20-30, close

    to the source of food, nesting material and water. Baya Weavers are best known for the elaborately woven

    nests constructed by the males. These pendulous nests are retort-shaped, with a central nesting chamber and

    a long vertical tube that leads to a side entrance to the chamber. The nests are woven with long strips of paddy

    leaves, rough grasses and long strips torn from palm fronds. Each strip can be between 20 and 60 cm in

    length. A male bird is known to make up to 500 trips to complete a nest. The birds use their strong beaks to

    strip and collect the strands, and to weave and knot them while building their nests. The nests are often built

    hanging over water[14] from palm trees[15] and often suspended from thornyAcaci
