How to isolate a specific "hot spot" in a video clip for exposure adjustments

Hello Adobe Premier Pro CC Forum

How is everyone? My name is Ira and thank you in advance for taking your time to read and consider a reply for my question below:

I have Premier Pro CC 2014.1 and am color correcting with RGB and/or Luma Curves for exposure and I am finding that on some clips there is one particular area that I'd like to affect, e.g. isolating that area with any exposure and/or color correction adjustments that do not affect the entire clip. I have not found one tutorial, nor any type of information on how this may or not be possible. Whenever I use any type of "exposure" related video effects I am able to balance the exposure and color clip-wide, but on one particular clip of about 15 seconds there is a shot of a baby hawk's head in his tree nest with sunlight and shadows throughout the tree, leaves, nest, sky, etc...It is the baby hawk's head only that I am trying to isolate in the clip to properly adjust the severe "hot spot" overexposure on the top of his head.

Using the various scopes I have balanced the overall luma and chroma at good levels according to the YC waveform and the RGB Parade: however, the baby hawk's head still stands out like a lightbulb and that is what I am trying to isolate for the correctives. My question is how can I isolate this area of the clip and what are the correctives that I'd need to use to properly expose just that area. It reads at just under 100 on the YC waveform.
