Basically, the idea was to check out the continued presence of bristled grassbirds which were detected to be breeding in the area. It is some weeks since I last checked the spot and hence the need to make recordigs. It the grassland beyond the lake on the right side of the road where the birds were first sighted, three birds were seen circling and makingflight calls while two additional birds were spotted inside the grass at close range (confirmed by binoculars). The latter did not make calls. It appears that one pair is nesting on the side of the road in very newly formed grass outside of the regular grassland area (Pressure of numbers), making a total of five birds in the area. Three other birds were spotted all singing in the grassland to the right (east) of the road to the south of the lake. The birds were seen taking turns to occupy the tall sacharum grass that stands tall among the imperata dominated grassland. [All the grasslands are mainly imperata with isolated patches of saccharum). In addition there were two more singing males in the grassland on the left of the road (west) south of the lake, making a total of 10 birds which is a great underestimate since bird density seems to be high as the distance between birds on the ground seem to be not more that 20-30 meters and the birds spilling out of the grassland. Therefore ten is a very conservative estimate with actual numbers likely be upto fifty. There were no grassbirds seen or heard in the relatively recently grown grass on the side of the road leading to the forest (part of the next record but relevant to the description here). Photos taken, sound recording made.
