Although a - EV is useful with white birds under high contrast situations (direct sunlight) here, with the low contrast light, the opposite is true, and a +1.3 seems reasonable to me. Underexposing, and it seems likely this happened here, is very detrimental as far as digital noise is concerned, especially at ISO 1600. I've stated this before; noise is a largely low luminosity beast, and under low contrast light you can shift the histogram curve to the right (toward overexposure) quite a bit and eliminate a great deal of the low luminosity elements. Then reduce exposure to normal in post-processing.
Whites, being high luminosity, are resistant to noise, and even at ISO 1600 very light parts of an image will show little noise. I'm not talking about blown(clipped) whites, but even these have the potential to be recovered in ACR given the lighting conditions of this image(low contrast).
Therefore, although you may have needed noise reduction for the background, your subject could have gone with out it. Hope I've been helpful~Bill
