Why are there NO birds at my feeder
Reasons why birds don't come to feeders is because for the time being food is plentiful elsewhere, so you'd need to up your game to attract birds to your own feeder setup.
Why are there NO bird at your feeder could be because feeders are unseen, thus are hidden out of view by any visiting birds. Could it be wrong bird feed is used when you need to cater to specific dietary needs. Offer bird food out of feeders to cater to any bird species, as you throw bird seeds over the lawn.
Let's just assume why there are no birds at your bird feeder when in fact there seems to be an abundance of different bird species coming and going in your yard.
Well, could it just be the bird feeder food currently available to birds its the wrong kind.
You see, different bird species require their own dietary needs, thus to offer dried mealworms to seed-eating birds currently occupying your backyard only - will only see curiosity - but never will wild birds feed on a wrong diet.
And if birds do eat what you are offering them, partially bird seeds or peanuts, it could just be these birds are not bird feeder birds.
Which means their ability at using a restricting bird feeder hung up on a bracket or branch is far beyond a specific bird species abilities.
To make sure birds do eat when they come to your yard, and continue to return for the foreseeable future - always offer bird food on the ground below feeders.
You can put bird seeds on the lawn but only after wild birds have begun to occupy the space, to at least be sure you avoid food waste.
In the meantime, why birds won't eat at your feeders could be because the feeders are hidden away. Be sure feeders are full of bird food which must be seen at all times - all while consider use of an open top platform bird feeder to feed all willing birds.
Birds arrival expected to soon
It may seem obvious but could it just be you are expecting backyard birds to arrive at your bird feeders way too early.
In particularly, can it be you are attracting birds to a new feeder of which, you need far more time for wild birds to find its location.
Its certainly a possibility and something you must consider to be fact, rather than believing birds simply turn up to a bird feeders whereabouts out of the blue.
Birds arrival at newly setup bird feeders can indeed take a few days for most people, so there's nothing to worry about where.
However, if there are NO birds at your feeder after a week, two weeks or even a month, then of course there's reasons to be concerned. Birds come to most bird feeders, old or new, thus it would be strange to see no activity on bird feeders at all.
I can assure you, despite these setbacks its absolutely possible to still attract birds to what is an unused bird feeder, you just need to change tactics.
Rather than allow bird food to rot within a bird feeder, you'd first need to find ways to attract birds to your yard - and only then will more wild birds follow.
Be sure there's plenty of greenery along with shrubs, seed-filled flowers, a water source and of course bird food available out of bird feeders, then give it more time to see what happens in the time its take to grow or plant all this.
And with all that, there's no time like the present to plant a tree to cater to most birds.
Feeders NOT seen in open
What people often forget when offering bird food to birds in what is a made in plastic or metal bird feeder, is its not often made to be seen.
Birds can only land at your bird feeder setup if its seen by sight, and as birds can't smell or sense food in the air - you'd have an hard task on your hands to attract birds to something they don't no exists.
With that in mind its imperative your particular bird feeder setup is out in the open.
And where you currently place your bird feeders with difficulty in attracting birds to it, you will absolutely need to think about re-locating feeders to a better area.
Where you can't go wrong to turn unused bird feeders to a feeder being swamped with different birds - is indeed to use many types bird feeders.
One isolated bird feeder hung up on a pole or a bracket can remain hidden, yet additional feeders - be it exact same models or new feeders - can be situated around the yard to be sure they are see wherever birds land.
Bird feeders can be hung in trees regardless because this is where birds will frequent.
You can place a bird feeder with a contrasting environment on its own bracket, off a clothesline, hang it safely high up on guttering to be spotted far away - or revert to a reliable bird feeder pole.
I recommend use of a bird feeder pole as you can use multiple feeders at a time, all grouped together using all kinds of wild birds food favorites.
Neighbors too inviting
With lack of commitment to the cause of continuing, and reliably - offering bird food to your local wildlife - of course no food in feeders will eventually see birds move on.
Where birds go if they can't eat at your bird feeders is a near neighbor, or if they must once local birds in a nearby tree will go further a field to feed, even if bird feeders are a few blocks away.
When birds get a grip on a new bird feeder location, birds will continue to head there daily as common backyard birds do remember where bird feeders are.
Lose sight of why you are feeding wild birds like you have, then they will abandon your yard in search of a more reliable food source.
Once more, your neighbors may have it together, meaning they are utilizing many kinds of bird feeders - while offering all the birds favorite bird food - which is similar to what birds eat in the wild.
If the neighbors have reliable natural foraging grounds it will be difficult to attract birds to your feeders - and if you have always continued to feed birds but they have just disappeared - absolutely can a better bird feeder setup invite more birds.
For the time being, open up your feeding area to attract many different birds to your feeders - along with a bird bath with moving water created via a fountain feature as to get birds attention with noise.
Foraging grounds to far away
Unfortunately, if this is the first time in your attempting to attract birds to your feeders, with no birds at said bird feeders, then you could just be unlucky.
Despite having a lush green lawn with plenty of earthworms to forage for, or indeed a leafy tree with plenty of natural insects or fruits for birds to eat - there may be an abundance of these ideal foraging grounds in the wild.
To have a backyard with such an inviting wild bird environment, it could just be birds are happy to feed outside of your property boundary.
Birds do come to feed out of bird feeders with lack of natural feeding grounds in an urban area or town; thus birds who remain in the countryside will indeed succeed in finding what they feed on, and when they want it.
Could it be your yard is located in an isolated area whereby you are surrounding in fields, wooded areas and farmland.
I will admit this environment can make it hard for a country home yard over what is a suburban yard - where birds are seen to feed because there's less natural foraging grounds in the area.
If you are situated in a suburban area with bird feeders used elsewhere, but not in your yard - could it be birds feed too far away in order to be close to their natural feeding grounds, and therefore their nesting sites.
To summarize
Don't be too disheartened with no birds at your bird feeders because its certainly a situation that can be rectified given time.
Birds can disappear for quite sometime if you stop/start feeding birds, as they simply find more reliable bird feeders in the neighborhood.
Similarly, if you've only just introduced a brand new bird feeder or a whole bunch of them to your yard for the first time - then remember this is new for birds in your area, thus its going to take time for birds to be attracted to these feeders.
With that being said, patience is key to getting birds to come to any bird feeder for the first time.
Why are there no birds at your bird feeder could be a fault of your own mind, with circumstances unknown to me so I won't be able to advise against it.
What you can focus more on is making sure your bird feeders are out in the open; birds only find feeders by sight, thus the hanging bird feeders on a bird feeder pole or tree branch must be seen as birds pass overhead or temporary rest in the yard.
With that, if you don't see birds in your yard very often then your yard isn't inviting enough.
You'd need to begin planting flowers, shrubs and bushes while making sure a lawn is laid to attract ground feeding birds - many of whom are incompatible at feeders.
Situate bright colored bird feeders with multiple bird feeders being found around the yard, while going big with a group of different kinds of bird feeders hanging up on a bird feeder pole together.
Just to be sure, offer birds bird food out of feeders just in case any visiting birds are exclusive ground eaters - or they don't have the ability to tackle an enclosed bird feeder.
