In reality, the angle of this shot and the small amount of plumage visible makes it impossible to decide whether it is flammea or cabaret with any certainty. If anything, it appears to be quite a pale specimen, so PhotographyGal's ID is a reasonable one. Without a view of the rump, the back, the undertail coverts and wings, any specific ID is only a guess.
Of course, they may only be variants upon a single species...
