Murmuration of House Sparrows
Murmuration of some birds is a strange but fascinating phenomenon. It has been observed with common starlings in Europe and India. In this phenomenon, groups consisting of thousands of birds fly together and are joined by more and more groups from the neighborhood. They fly together going up and down, changing direction suddenly making breathtaking patterns. But even being so close, they hardly collide with one another.
I was lucky to observe this phenomenon by chance but not with starlings which are not in plenty in our area but with House Sparrows.
So It was a double bonus and surprise. I at least have the notion that house Sparrows live in houses in small groups and also the most common belief that the population of house sparrows has declined to dangerously low levels. But I was proved wrong when I spotted them in the fields.
It was dusk time when it all started. I was roaming with my camera in the field located nearby to my home. There are two or three excavated areas in the fields which have become water bodies and Reed grass grows in them in adundance. It was early April and wheat crops have been reaped.
Suddenly, groups began arriving and joining over an area of say about 1 kilometer radius. The group will perform those maneuvers and suddenly once in while land on the electric transmission wires passing that place or plunge into the reeds. The numbers must be thousands. Then suddenly they will again take off and perform those maneuvers in the sky. This went on for till the darkness descended.
This was observed by me on three different evenings.
Lastly, since two day in a row, the Sparrows have left the place suddenly. Baffling me. Why they have left and where they are headed. One apparent change is of course the reaping of the wheat harvest in those fields. But still the explanation is uncertain.
