Searching the "Comments on Specific Birds" forum returns just two entries for "hawk" -- common black hawk and short-tailed hawk. Should I start a new topic in that forum to ask non-identification related questions about red-tailed hawks and other birds not already listed? Or is that up to Mitchell? I don't see any way to begin a new thread in that forum and suspect it's restricted.
BTW, it's interesting to see the names "Mitch Waite" and "Waite Group" again. I used to buy rather a lot of your programming books. Interesting new line, this.
