Baya Weavers are small birds of house sparrow size. The scientific name is Ploceus philippinus. What separates them from other birds is the beautiful nests they weave from the grass stalks, mud blobs.
The name weaver itself justifies the mastery is weaving very elaborate and elegant nests hanging from the branches of very high palm trees, thorny acacia trees. Usually these trees are near the water pools, scrub grasses where they are safe from predators.
It is male domain entirely to make the nest. When it is in the almost halfway stage, they invite the females by flapping their wings and if the female approves the nest, it means that she will reside with the particular male, mate and raise the new chicks. If she doesn’t approve, the structure will be abandoned and weaver will feel dejected and sometimes tore away the nest. It starts making newer one.
These birds come to our area in North India, at the peak of summers and by the onset of monsoon rains, have their nests completed. They visit the fields for foraging the seeds both raw and fallen after ripening.
After monsoons, and winter coming, they migrate to slightly warmer areas like western India where food is available and weather is not harsh.
The birds are gregarious and live in flocks. They can be located from the noises they make.
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.
Scientists have marked the time since the Earth began its life. They have divided it into different Epochs, Periods, Eras and Eons progressively in increasing time groups.
We are living in the following division of time.
Holocene epoch began roughly 11700 years back and continues till present. United States Geological Survey (USGS) has divided this time into three ages namely
Greenlandian: 11700 to 8326 years ago
Northgrippian: 8326 to 4250 years ago
MEGHALAYAN: 4250 to present date
MEGHALAYAN age marks the time when a mega drought devastated civilizations across the world, including those in Egypt, Greece, Syria, Palestine, Mesopotamia, The indus Valley and the Yangtze valley. Drought lasted some 209 years and supposed to be prompted by shifts in ocean and atmospheric circulation.
Geologists chose the name “Meghalayan” as a nod to a rock sample they analyzed from Meghalaya, a northeastern state in India, whose name means “the abode of clouds” in Sanskrit. By analyzing a stalagmite growing on the ground of Mawmluh Cave, geologists found that each of the stalagmite layers had different levels of oxygen isotopes, or versions of oxygen with different numbers of neutrons. This change marked the weakening of monsoon conditions from that time.
