Thanks, ajoin. I think you are right. According to "http://en.wikipedia.org/wiki/Red-eyed_Dove":
"Red-eyed Dove is a largish, stocky pigeon, typically 34 cm in length. Its back, wings and tail are pale brown. When flying, it shows blackish flight feathers. The head and underparts are dark vinous-pink, shading to pale grey on the face. There is a black hind neck patch edged with white. The legs and a patch of bare skin around the eye are red."
There is no red bare skin around the eye of the one in the photo. So it should be Spotted Dove.
Sorry for any inconvenience caused and thanks again.
(Will change back the title soon)
