Nest of a 'Plain Prinia', Kosgama, Avissawella, Sri Lanka.

I saw the nest of a 'Prinia' on a tree close to the entrance of a house at Kosgama, Avissawella. I took the picture of the nest above. You can see the chicks inside. One bird flew out and sat on a branch closeby. I presume it was the mother. I took a video of it. Click on the link below to see the mother and its chirping.
