Bluebirds on a Cold Day

I work facing our deck and can watch the birds come and go.  I can almost sense when the bluebirds might decide to come to feed.  They tend to come along with other colorful birds, cardinals, and yellow warblers.   Today I decided to get my camera out should they decide to show up...and they did.  There were probably 5 or 6 together.  They don't stay long either!
