I recently took pictures of Spotted doves (Spilopelia chinensis) during their courtship. The one on the right, is large with a off-white breast and the one on the left is comparatively small with dingy reddish white breast.

My professor and I presumed that the one on the right is the male and the other is the female. The larger one mounted the other during cloacal kiss.

I've checked Wikipedia and other sites which seem to copy Wikipedia, they say that the species does not show sexual dimorphism. On the other hand, this website claims that there is a difference.

Does it show sexual dimorphism?

First I think that is a Western Spotted Dove (Spilopelia suratensis), now splitted from the Eastern spotted Dove (Spilopelia chinensis). In your area there should be both species but the red iris and eye-ring should indicate the Western. Sexes are alike so there are no signs you characteristics you can check (source, handbook of the bird of the world, which is the most updated and reliable source in many occasions). Males sing much more often than females (so you can observe this behaviour) and in many species, but I dunno about this one, is the male providing food to the female...so I think your guess is right!

All the best,

Have fun

    $\begingroup$ I am sorry I think there is not much more information that the one provided by wikipedia. Also this specialized website, which I trust, birdforum.net/opus/Spotted_Dove repeats the same information. $\endgroup$ – have fun Oct 6 '16 at 13:18
