Dennis,

We haven't seen any signs of breeding but there are either a few sticking
around or a lot of them passing through. Your calculation the other day made
me think that it may a the latter. There were quite few sightings around the
zoo two to three weeks ago. We haven't seen as many the last few days.
Since my office is no longer in "Camp David", our administrative trailer
complex near the north enty, I'm not the best judge of the current numbers.
Greg Toffic or Lynne Givler may have a better idea.
