(4/4/12) 35, 28, 63 , move to ficus and scattered;

It seems that the sparrows prefer medium sized trees for their roosting. They do not move out on windy and chilly days. But a general trend of drastic reduction maybe either due to local migration or encroachment of crows later.
Some sparrows peck in the interlocking bricks near the hedge
when even a single pigeon joins them all the sparrows fly away. Generally they fly in groups of 10-15 when they are in large number otherwise they fly singly. Their reduced number in summer coincided with encroachment of crows in the garden.
The sparrows nest on the east side of our building as they get full protection from the pigeon. But on the west side grill has an opening through which pigeons enter. Therefore they do not nest on that side besides whenever the sparrows nest a pigeon comes and sits on the vantage point of the pipe everyday and monitors the movements of the sparrows specially whenever the eggs are laid. This goes on until the fledglings leave the nest. This indicates competition between sparrows and pigeon for food and space for nesting.
