Black Breasted Weaver: Master Craftsman
All birds make nests to raise their chicks. The nests range from simple twigs heaped together to most elaborate. Weaver birds excel as craftsman in making intricate nests.
The area they choose for nesting is carefully chosen. There should be thorny tree like acacia or lofty trees like palms. Idea is to deter predators like snakes, shikra etc from destroying the nest for eggs. Then there should be plenty of food available near by. So they choose the areas near agricultural land. Then there should be nesting material available like bulrush grass in bogs.
While baya weavers make the nests on trees their cousins Black Breasted Weavers also known as Bengal Weaver or Black Throated Weaver (Ploceus benghalensis) make their nests inside thick bulrush grasses. Their nests are not easily seen on cursory look. It is so intricately hidden.
Only male birds do the nest making. They make hundreds of trips to bring the grass blades which they cleave from the grass stalks. Females are invited to inspect the partially completed nest, if a female okays the nest she would move with male for starting the family.
In our area there are plenty of weavers birds. We located one such nest in the making. From a distance without disturbing the bird made a video which I am sharing with my friends on wordpress.
