Feeding birds through winter

Winter is the season the whole setup is for. Days are short, insects are gone, and a small bird can burn through most of its fat reserves overnight. What you put out genuinely matters more now than at any other point in the year.

1. Fat

Energy density is what counts in the cold. Black oil sunflower publishes 24% minimum fat. Suet is higher and is the single best cold-weather offering — Project FeederWatch names woodpeckers, nuthatches and chickadees as the birds a suet cage attracts, and all three are winter regulars.

Peanuts and shell-free nut mixes are also strong here: Lyric Delite publishes 35% minimum fat, the highest of any mix we list. What to avoid is a filler-heavy bargain mix, which is poor value at any time of year and actively unhelpful now. Seed picks here.

2. Access

A full feeder with iced-over ports is an empty feeder as far as a chickadee is concerned. After snow or freezing rain:

• Clear snow off perches, ports and the roof.
• Check the ports are not glazed over — a gloved finger is enough.
• Knock accumulated snow off the tray so it does not turn to ice.
• Check the seed has not frozen into a block, which happens when damp seed then freezes.

Feeders with a roof — hoppers especially — earn their keep in this season for exactly this reason. See hopper feeders.

3. Consistency

Birds learn which sources are reliable and route their day around them. In deep winter, a feeder that is full every morning is worth more than a bigger feeder that is empty half the week. This is the strongest argument for capacity: not that birds eat more, but that you are less likely to leave it empty.

If you are going away, either fill a large feeder before you go or ask someone to top it up. Birds will not starve because your feeder is empty — they will simply go elsewhere — but there is no reason to make them.

Water, which people forget

In a hard freeze, open water can be harder to find than food. A shallow dish, refreshed when it freezes, is genuinely valuable. Heated bird baths exist and work.

Two cautions: never add antifreeze or salt to a bird bath — both are harmful — and keep it shallow, an inch or two, so birds can drink and bathe without difficulty. Clean it as often as you clean the feeder.

Cleaning does not stop in winter

It is tempting to skip it when the hose is frozen, but wet snow in a feeder produces damp seed just as rain does. Keep to the every-week-or-two schedule; use hot water indoors and dry the feeder completely before rehanging it. Method here.

What winter brings that autumn did not

• Bigger flocks. Winter finch movements can fill a nyjer feeder that was quiet all autumn.
• Hungrier squirrels. Preference-based tactics like safflower work less well when alternatives are gone. The hardware still works.
• Hawks. A concentrated flock at a feeder attracts them. Give small birds cover to reach.

Do birds become dependent?

The concern is common and is not borne out by how birds actually forage: feeder birds use multiple food sources and continue foraging naturally. The honest framing is that feeding is a supplement, and the responsibility that comes with it is hygiene, not an obligation to never stop.
