I saw this bird in our backyard last week sitting like this on our compound wall. I saw it continuously for nearly 6-7 days. I have never seen this type of bird earlier. I have seen a gray bird with black polka dots sometimes, but couldn't photograph it. It was looking like, nearly a crow but with slightly flat belly. I don't see it now.
I tried to take a close-up photo and zoomed, but it looks blurred!
