Here's one explanation. “ Borchelt suspects his rufous may stick around longer. “What I think is happening,” he says, “is that birds from the Canadian Rockies go east across the Plains on fall migration (instead of down the eastern side of the Sierra) and find patches of resources where they hang out for the season. For rufous, winter here isn’t that much different from early spring in the Rockies—they’re really hardy little birds.” “There’s an emerging consensus that ‘vagrant’ hummingbirds [those that winter outside traditional ranges] are some kind of genetic ‘scouts’ programmed to prospect for likely winter habitat,” adds Borchelt. “Mine seems to have hit pay dirt. She may have moved in for the season . . . as long as I keep the feeder unfrozen!” ” If for some reason (ahem) the internets and electronic broadcasting should be interrupted, I know that I will find ample entertainment watching our grandchildren (before they get too old) and our birds, of which we have hundreds (birds, not chillens)  that make our yard "home."  Winter hummers would be a real treat.  Now, if we can somehow get bluebirds and orioles ... .
