I took a tour of the upper bay today, chasing birds reported recently by Matt 
Hafner, Chris Starling, and Walter Ellison, plus finally getting around to seeing 
the Great White Heron.  Luckily, the heron wasn't deterred by the cold 
weather.  In fact, I saw it defend its territory against a regular Great Blue 
Heron, so maybe it's planning to stick around for a while longer.
