*Update July 4, 2011. Continued observation of the "babies," leads us to believe this is one of them, and not an adult.

There is so much variation even in what we know for sure is the same hawk's expression. The Cornell Lab of Ornithology's website shows huge variation in the color and pattern of feathers. I'm giving up trying to tell the adults and babies, as well as the male and female apart. (Although, when seen together, the female is clearly significantly larger than the male in this family group.)
