As this discussion seems quite interesting, I am posting some additional images of the same birds. In image 1 you can see both birds, second one is in the background with tertails visible. Image 2 shows details of bird from the back. 3 and 4 are some additional images, but not sure which if they are the same bird or different individuals.
About the yellow staining on the face, it is possible that it might be due to vegetation. Around this time of the year most of the plants are have shed their seeds and these 2 were foraging on the ground.
