Well the current cold snap appears to have slowed down birds as whole, but the hawks appear to be doing just fine. They continue to mate, although there appears to be a direct correlation between the presence of my camera and when they chose to "frolic". Anyway, the female (I presume) appears to be spending quite a bit more time on the nest and the male seems to be bringing in food. The female calls (for minutes at a time) for the male who eventually shows up with food. He lands on a branch near the nest, and waits for the female to fly over to him to grab the food. She then eats it, and heads back to the nest. The pictures below are of the female eating a rodent.
It's a bit hard to see in this photo, but there is a rodent in the hawks claws:
