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.

Tarangan Complex is a locality with high rise buildings in which almost 350 families of higher middle class reside(Map 1). In front of these buildings a big open nallah flows and flyover is built on the east side of this complex carrying heavy traffic day and night. Korum mall has come up on the north side. All the buildings have a garden and tall trees line the side of the nallah.
The drainage and water pipes are covered by concrete walls and frontage have a iron grills of 3.5 cm square openings. These openings give free access to the sparrows and avoid menace of pigeons and other animals. In the beginning crows were not seen in this locality even though cawing of crows could be heard only in the early morning.
The garden receives cow dung manure and has mainly Ficus hedge which continues into bamboo hedge on the road side of this complex. At the end, the bamboo hedge turns into thicket (5 feet breadth, 13 feet in length and 11 feet height) which becomes short and sparse as it continues. The thicket is the roosting site of the sparrows in the morning. In the evening, sparrows gather in the ficus and sparse bamboos chirping continuously and then retire to roost in the bamboo thicket.
The sparrows chirp for almost 45 minutes before sun rise and then leave their roosting place invariably within 15 minutes in groups of 10 to 15 just before the sunrise. The number of sparrows was counted from the two ends of the thicket (site 1 and 2 respectively) for half an hour. Some of them rest for a few seconds on a nearby tree probably to warm up and then fly. A few of them return back. The returned sparrows are subtracted from the total number of sparrows to give a correct picture. (Table 1).
