I think that John A is correct to raise the caution that it may be an (escaped) Marabou Stork, quite a common species in captivity. Based on the distinct paleness of the coverts can we rule out Lesser Adjutant, which should show no pattern on the wing? However, I am not sure about separating Greater Adjutant and Marabou from this photo. I can't see any yellow colour on the neck (which would favour Greater Adjutant) but that may just be because the bird is quite distant. Are there any more photos?
