Capped Heron at Howard

Wally Murdoch reports a Capped Heron on a creek by the stables at Howard Air Force Base.
On 27 June 1999 at 0640 hours I observed a Capped Heron at Howard Air Force Base. It was feeding in the small stream to the right that crosses under the main road to the base just before the Stables as one travels South. I stopped to observe it better, it saw me and flew into the underbrush upstream.
It was about the size of a cattle Egret, entirely white except for the beak which was blue and the top of head which was black.
