​After rejoicing just 8 days ago over 4, occasionally 5, Cardinals hanging around the place along with a plethora of other familiar local birds, suddenly, with the exception of an occasional junco or chickadee, and a pair of blue jays, they've all disappeared.  The feeders  remain almost full even after I emptied and refilled them in case seed was stale.  I'm thinking the change probably occurred around the time of the ice and deep cold.  Is this a common occurrence?  How would we know if the storm wiped them out?  Any ideas?

Thanks.
