Little birds find it hard to forage for nibbles when it's snowing (which it is). They also need food and water every 24 hours to stay alive when temperatures drop (which they have), so if you're lucky enough to own a patch of garden, it's always kind to leave something out for the little feathered cuties. We bought a bucket load of seed/fat balls, but they came naked, without the little fluorescent netting needed to attach them to branches/hooks. Turns out old fishnet tights and a little twine do just as well. Win!
