We put out a bird-feeder bell before Shabbos, as part of our Shabbos Shirah celebrations. No birds braved the freezing cold over Shabbos, but we had hopes for the rest of the week...
...Until just now, when I heard a thump outside and got this picture:
Those are evil-looking eyes.
I don't suppose raccoons ate the manna left out on Shabbos by Dasan and Aviram?
Now that we're discussing Shabbos Shirah and leaving food for birds, here's a halachic note on the subject:
May I feed wild birds on Shabbat Shirah?
There is an old custom of leaving grain or bread for birds on Shabbat Shirah. Some suggest it is a reward for their song at the Sea; others link it to the way the birds ate the false manna dispersed by Dasan and Aviram on Shabbat.
Some oppose this practice, insisting that food be left out before Shabbat. This is because the sages forbade feeding wild animals on Shabbat (1) because there may be strain involved and (2) because one might forget the laws of Shabbat and trap these creatures. They permitted only feeding domesticated animals which depend on us for food.
Other authorities defend the practice of putting out food on Shabbat Shirah, arguing that there is no strain involved and that the birds are beyond trapping when the food is placed outside. Further, we are doing it not for the birds' sake, but for the sake of our own custom.
