It really was an unexpectedly poor turn out of our birds. We can usually rely on three sorts of tits (occasionally a troop of long-tailed as well), goldfinches, robins, blackbirds, dunnocks, pigeons and doves, starlings and sparrows, and get sporadic visits from bullfinches, siskins, greenfinches (though rarely recently, as mentioned previously) and sometimes woodpeckers and sparrowhawks.
They must all have been keeping their heads down yesterday - not surprising, really.
