I usually only feed birds during unseasonable weather (either unseasonably cold, or a rare snow which I figure covers much of the ground where they'd usually find food). The rest of the time I presume they can find food on their own. Surprisingly, it takes only a couple of days before dozens of birds find the food. I put out a birdbath when we had an unusual heat wave, but didn't see any birds using it, though we had some squirrels stop by in the daytime, and a raccoon family visited at night to get a drink.
