No birds at my feeder: a fault-finding sequence

The short answer

• Split the problem first: a feeder that has never had birds is a discovery or placement fault, and a feeder that lost its birds is a food, predator, season or hygiene fault. They have different fixes.
• A new feeder in an established neighborhood usually takes 1 to 2 weeks. On a bare new-build lot with no mature trees within 100 ft, 3 to 6 weeks is normal and nothing is wrong.
• Stale seed is the most under-diagnosed cause. Nyjer in particular goes dead within weeks and birds simply stop touching it, while it still looks perfectly good to you.
• Two calendar windows empty feeders every year for reasons you cannot fix: late May to early August, and a heavy acorn or conifer seed year in October and November.
• Change one variable at a time and wait seven days. Changing four things at once means you never learn which one was the fault.

An empty feeder is a fault, and faults are found by testing in order, cheapest and most likely first. Doing that badly, by changing the seed and moving the pole and buying a second feeder in the same weekend, is how people spend three months without ever learning what was wrong.

First: sudden, or never?#

This one question splits the problem in half, and the two halves share almost no causes.

Never had birds. The feeder has been up for days or weeks and nothing has ever landed on it. This is a discovery problem or a placement problem. The birds have not rejected your feeder, they have not found it, or they will not cross the ground it stands on. Go to checks 1, 3 and 8.

Had birds, lost them. Traffic was normal and then stopped, either overnight or over a couple of weeks. Sudden stops are predators, food gone bad, or hygiene. Slow fades are seasonal, or a neighbor, or seed quietly going stale. Go to checks 2, 4, 5, 6 and 7.

One more free clue before you start. Is the feeder empty or full?

• Full feeder, no birds. Nobody is coming. Work the list below.
• Empty feeder, no birds seen. Something is coming, just not while you are watching. Squirrels, a grackle flock or House Sparrows can clear a feeder before breakfast, which is a different problem with a different fix.

The eight checks, in order#

1. Time on the pole#

Most "no birds" reports are a feeder that has been up for four days.

Working estimates rather than measurements, and weather moves all of them:

Starting in winter is faster than starting in June, because flocks are searching hard and natural food is thin. If your feeder has been up less than 14 days in a normal suburb, the correct action is to do nothing for another week.

2. The seed#

The single most common fixable cause, and the one people are most confident is not the problem.

Seed does not have to look bad to be rejected. What birds are detecting is rancid fat, and it happens well before mold appears.

• Sunflower. Crack a few. The kernel should be plump and cream-colored, and smell faintly oily and nutty. Gray, shrunken, dusty or sharply "paint-like" means it is finished.
• Nyjer. The worst offender by a distance. It is heat-treated so it cannot sprout, it dries out in weeks, and goldfinches will sit on a feeder full of dead nyjer and refuse it. Pinch a few seeds: fresh nyjer marks your fingers faintly with oil, dead nyjer is dry dust.
• The bottom of the feeder. Seed at the base of a tube can be months old while the top looks new. Topping up without emptying is how a good bag of seed goes bad.
• The bag. Seed stored in the garage through a humid summer, or in the original paper sack on a concrete floor, degrades fast. See storing birdseed.

If in doubt, dump it. A fresh bag of black oil sunflower is the cheapest diagnostic test in bird feeding, and it is also the seed with the broadest appeal, so it doubles as the control condition.

Fill for the scout species while you are at it. Chickadees are usually the first bird to find a new feeder anywhere in their range, and they bring the mixed flock with them:

1. Black oil Top
2. Hearts Top
3. Peanuts (shelled) Top
4. Suet Top
5. Mealworms Top
6. Safflower Yes

3. Cover and sightlines#

A feeder in the middle of a lawn, 30 ft from the nearest shrub, is a place small birds will not linger. They need somewhere to sit before they commit and somewhere to bolt to afterwards.

The number is 10 to 12 ft to dense woody cover. Closer than about 5 ft and you have built a cat ambush point. Further than about 20 ft and every visit is an exposed crossing. If your yard has nothing at that distance, a stacked brush pile of prunings, 4 ft by 6 ft, put up in an afternoon, is the fastest fix available and works within days. The permanent version is planting, positioned using where to put a bird feeder.

Also check what is above. Birds approach a feeder from a perch. A feeder with no staging branch within 15 ft gets found late and used cautiously.

4. Is something hunting the yard#

Sudden and total silence, especially with a scatter of feathers on the ground or a bird-shaped smudge on a window, is a predator.

• Accipiter. Birds vanish for several days after a hawk starts a circuit, and stay away for days after it leaves. Full detail in hawks at feeders.
• Cat. More persistent and less obvious. Watch at dawn. A cat that has learned the yard turns a busy station into a quiet one within a week. See cats and feeders.

Neither justifies dismantling the station. Both justify changing the geometry.

5. The calendar#

Two windows empty feeders every year across most of North America, and neither is a fault.

• Late May to early August. Insects and green seed heads are everywhere, nestlings are being fed caterpillars rather than sunflower, and adults are molting and staying under cover. This is the deepest annual lull and it catches out every new feeder owner. Summer feeding explains what to keep offering.
• A heavy mast autumn. In a good acorn, beechnut or conifer seed year, October and November feeders can sit untouched until the first hard weather, then fill up in a single cold snap.

Add migration on top: your White-throated Sparrows and juncos are seasonal residents, not permanent ones, and some winters bring no siskins or redpolls at all.

6. Somebody else started feeding#

Feeder birds work a circuit, and a circuit is a local competition. A new feeder two doors down, especially one with fresh seed and better cover, will take a share of your traffic within a fortnight. So will a neighbor's new dog, a construction project, or a hedge that got cut down.

This one is diagnosed by walking around the block and looking at other people's yards. There is no fix beyond being the better station: fresher seed, better cover, water.

7. Hygiene and disease#

Birds avoid a fouled feeder, and they are right to.

• Droppings on the tray, wet clumped seed at the base, or a slimy film inside the tube all reduce use before they cause illness. Wash on the schedule in how to clean a bird feeder.
• Visible mold means empty, scrub and start again, and it means the seed goes in the bin. See moldy seed.
• A local outbreak of salmonellosis or finch eye disease will thin a yard quickly, and sometimes the correct response is to take the feeders down entirely for a couple of weeks on agency advice. That decision is covered in bird diseases at feeders.

8. Can a bird see it at all#

Birds find feeders by sight, from above and from a perch. A feeder under a deck roof, inside a dense shrub, on a shaded north wall or below a fence line can be genuinely invisible to a bird flying over.

Three things make a new feeder findable:

1. Put a shallow layer of seed on top of the feeder lid, on a nearby wall cap, and on a small patch of open ground beneath it, for the first two weeks only.
2. Keep the seed level high enough to be visible through the tube or above the tray edge. A quarter-full feeder reads as empty from the air.
3. Keep the approach open from at least one direction, and keep a perch within 15 ft.

Change one thing a week#

This is the part that actually determines whether you solve it.

Water deserves its place on that list. In dry regions and in late summer, a shallow moving water source pulls in birds that will not touch seed at all, including species that never use feeders. Keep it shallow, under 2 in at the deepest point, and keep it clean.

The five-minute test that tells you what you are working with#

Before you conclude your yard has no birds, sit outside at first light with no feeder in view and listen for ten minutes. Then walk the block.

• Birds are present in the neighborhood but not in your yard. It is habitat or predators. Checks 3, 4 and 8.
• Birds are present in your yard but not on the feeder. It is the food or the feeder design. Checks 2 and 7, then ask whether the feeder suits the species you actually have, using how to choose a bird feeder.
• No birds anywhere within a block. It is your area, not your feeder, and the answer is planting and water over a season rather than anything you can buy.

When there is genuinely nothing wrong#

Some yards are hard. A new development with turf, saplings and no seed-bearing plants for a quarter mile will not produce a busy feeding station in its first year, no matter what you hang or fill it with. The route in that case is habitat first, feeder second: plant cover, add water, tolerate the wait, and read attracting birds to a new feeder for the full startup sequence. Yards get better every year. Feeders do not.

Frequently asked questions#

How long does it take birds to find a new feeder?

In a neighborhood with mature trees and other feeders, usually a few days to a week. In an average suburban yard, one to two weeks. On a new-build lot with no mature trees within 100 ft, three to six weeks is normal and some yards take a full season until the planting matures. Winter is faster than summer, because natural food is scarce and flocks are actively searching. Before you change anything, make sure the feeder has genuinely had two weeks of fair trial.

Why did birds suddenly stop coming to my feeder?

Sudden means predator, food or hygiene. Check in that order. A cat or an accipiter working the yard empties it within a day, and the effect lasts several days past the predator's last visit. Seed that has gone stale, damp or moldy gets abandoned just as fast, and the bottom of the feeder is where that starts. A dirty feeder or a local disease outbreak does the same. A gradual fade over two or three weeks is more likely to be seasonal or a neighbor's new feeder.

Do birds stop using feeders in summer?

Yes, and it is the most common false alarm in bird feeding. From late May through early August, insects and seed heads are everywhere, adults are feeding nestlings on caterpillars rather than seed, and many species are molting and skulking. Feeder traffic can fall by most of its spring level with nothing wrong at all. Keep offering fresh water and a small amount of fresh seed, and expect the numbers to return in late August and September.

Can old birdseed stop birds coming?

It is one of the leading causes. Seed oxidises, and the fat that makes it worth eating goes rancid, which birds detect long before you do. Nyjer is the worst case: it is heat-treated so it cannot germinate, it dries out fast, and a bag opened last season is often ignored completely. Pinch a few nyjer seeds between your fingers. Fresh nyjer leaves a faint oily mark. If it crumbles dry and dusty, it is finished.

Should I move my feeder if no birds come?

Move it last, not first. Position is worth checking, but it is the change with the longest reset cost: every move restarts the discovery clock. Confirm the seed is fresh and the feeder is clean, then check that there is cover 10 to 15 ft away and nothing hunting the yard. If all of that is right and the feeder has been up for three weeks with no visits, then move it, and give the new position two full weeks before judging it.

Do birds tell each other where feeders are?

Effectively, yes. Chickadees, titmice and nuthatches move in loose mixed flocks in autumn and winter, and other species follow them to food. That is why the first bird is the hard one and the tenth is easy: once a chickadee has your feeder on its circuit, the flock arrives with it. It is also why a feeder that is visible from a perch used by passing birds fills up faster than an identical feeder tucked under a porch roof.
