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.
Weaver Birds visit our area when summers are at peak. They stay here, make beautiful nests using the grass stalks and mate and raise the chicks for new generation. Most common are Baya Weavers which make nests on the acacia, palm trees which are difficult for predators to approach.
Birds choose the places to nest in the area where food and water is available and safe from disturbances.
But there is another variety called Black Breasted Weaver. It is master strategist in the choice of the area fulfilling all three criteria. They make different kind of nests and use the long grasses to hang the nests. I accidentally discovered the nest while stopping on the scooter near a roundabout near Ghaggar river bridge in Panchkula Haryana of India.
On the side of road are trenches and crests and a water pool, I saw the nest last year. This year also I saw these nest almost in the same spot. Area is very difficult to approach. I somehow approached at not so favourable distant but still very far for better pictures of this small beautiful bird. It makes nest if the tall reed grass and so much camouflaged that you cannot see it clearly. Only once or twice it sat on the top of dry grass.
