To follow-up on Rob's message, I would say that we're in the midst of an
Orange-crowned invasion.  In addition to the 3+ that Ottavio found,
there's a report of an OC at Hains Pt. on 12/18, and another from Jones
Pt. (actually Alexandria, but 50' from DC waters) yesterday (12/23). 
Has anyone checked the LBJ grove recently?
