Ashy Prinia

This sparrow sized bird is generally found in areas with reeds bordering streams and moist grassland. As I was photographing these birds, I realised that they enjoy sitting on a thin reed and swinging about, just like how a kid plays on a swing. The reeds were barely strong enough to carry their weight.
The first photograph was taken in fading light and hence lack details, but posted it to highlight the colour of the bird's posterior.
The bird produces a peculiar 'kit-kit-kit' sound which sounds like electric sparks. The exact way in which it produces this sound is still not fully understood. The bird also builds beautiful nests either of stitched leaves like a tailor bird or of woven fibers, like a weaver bird.
