A plain bird that you have shown very well Satish.
I like the colors of the BG and the raised foot.
The eye is really well detailed.
I wish we had the light you do here in Nova Scotia. I don't think I have ever shot at ISO 200!

Agree with Randy on the motion blur in the head. When photographing birds, there is really no reason to go below ISO 400, but now that I see the 550D, not really sure as far as that body. Blur in foot works well. Lovely perch and BG. Might consider a tad off of bottom and right. Looks a little centered. Maybe even a tad more on top if you have it.
I too never go below ISO 400 for birds...even static ones as you never know what they'll do next and you may need the SS to freeze the surprise action. I agree with the others, but I want to point out that he perch and especially the BG are fantastic.
