Y Prakash Rao - Swarnandhra Colony Yapral Secunderabad Andhra Pradesh

There is one pair here in the colony that used to visit my house in search of a nesting place. I had placed four wooden nests last year in apr may 2011. I noticed that there was stiff competition between the Scaly Breasted Munias and the sparrows. Two nests were colonised by the munias. One was used as roost by the young ones last winter. The other was used by munias to breed. However the eggs(five) were never hatched in this one. How ever adult munias used to visit this nest box. The other two nests did not have any takers.
This year in Feb Mar the two nests that were not occupied last year were hurriedly occupied by a pair of Indian Robins. hey placed nesting material in both the nests simultaneously but used one to hatch the eggs. The sparrows tried to occupy one of these nests. However the aggressive male Indian Robin attacked the male sparrow from rear and probably piercing the bird with its slender pointed beak. The sparrows were not found here again. How ever there is one nest in the colony in a toilet ventilator made of grass. The house was not occupied at that time.
