Do bird baths need to be elevated
To know what bird species frequent your garden more often, would help you make up your mind if a bird bath on a stand, or one positioned higher off the ground is a must.
Bird baths do not need to be elevated, but can attract more backyard birds within the US. Backyard birds use of bird baths can imitate their foraging behavior in the wild, thus birds that feed up in trees would drink or bathe off the ground more. Ground level bird baths would be used, but less so.
Its all about experimentation, so you may only know the answer to this burning question of do bird bath need to be elevated, with only many months of use.
My personal experience would put an elevated bird bath design at an advantage point as oppose to a bird bath designed to sit on the ground.
Why that is, most birds that visit our yards are those that forage at elevated points, thus this behavior is similar to when these same birds drink or bathe in the wild.
And while its certainly possible to see birds that forage higher off the ground use a bird bath sitting on the lawn - its would benefit you to cater to their needs.
Ground level bird baths are limited in that less birds feed on the ground, so expect fewer visitations if you don't get many ground feeding birds in your yard.
Only cater to the birds species you have in your yard, as this will tell you what type of bird bath would be the best one to use. To receive only Northern Cardinals for example, would require a ground bird bath.
Why must you only pick one type of bird bath over another, when a ground bird bath can be used. But so to can a bird bath on a stand for that all important elevated position.
Elevation attracts more species
Whilst is not necessary to make sure a bird bath is elevated, I found by experience that those that are higher off the ground see more visitation.
Now it must be said most of the birds that visit my yard, tend to be those that feed on higher points in the wild - thus its natural to see their foraging habits translate into their drinking and bathing habits.
While ground feeding birds will happily make more use of a ground level bird bath, that is not to say they are not capable of using a bird bath on a stand, or one that is hanging up.
Similarly but made more complicated, are hanging bird baths or ones located to obstacles that can lead to landing and taking off made near impossible for less agile birds.
I would say that elevated bird baths do need to be elevated if you receive visitation by more higher up foraging birds, but that is not to say all birds won't use your bird bath if in times of need.
Bird baths on a pedestal take center stage over a less visible hanging bird bath, thus an elevated bird bath can be spotted more if positioned out in the open, leading to more use.
Ground bird baths are limited
Whilst ground bird baths are certainly going to benefit many of you, there are limits to what kind of birds will indeed use a bath placed dangerously on the ground.
In fact you may find a ground bird bath open to more nuisance birds or indeed become a water source for predators or common backyard pests.
Ground bird baths will benefit those of you who are seen to receive more visits to your backyard by common ground feeding birds, such as Blackbirds or Northern Cardinals - but less so by Chickadees, Orioles and Goldfinches, to name a few.
Often a backyard landscape can call for a ground level bird bath, so do go ahead and set one up if it matches the decor of the garden.
There's certainly no harm in setting up an additional elevated bird bath design as to attract more species, rather than limiting yourself to a only one bird bath location.
Ground bird baths can be limited in terms with birds that are ground feeders only, but that is not to say it can bring a few wonderful, yet regular surprises.
Birds feel safer higher up
If I take into consideration only those common backyard birds that are likely to visit our yards across the US, it mostly relates to birds that feed higher up in nature.
As birds forage, they do so within trees or higher up in vegetation; never on the ground as its in their nature to only forage high up off the ground.
Similarly to how most birds in our yards like to feed off bird feeders hanging off a bird feeding station or one that might be hung off a bracket.
Knowing all that, its likely an elevated bird bath, while not always necessary, will see more success in terms of attracting birds to actually use it.
Bird baths do not need to be elevated, be it on a stand or hanging off a bracket, but most birds tend to be more drawn to this setup than a bird bath bowl that is designed to sit on the ground.
Any bird that eats higher up in the wild doesn't do so to feel safe, but birds that do feed on the ground will take your ground level bird bath in their stride. Whereas if they're forced to bathe or drink on an elevated point - at least you'd be offering a safe haven.
Easier to keep clean
What better way to evaluate if a bird bath needs to be elevated or not, by simply looking at your own health.
You see not everyone can bend and lean, especially the elderly, so therefore an elevated bird bath at waist height, or indeed chest high can benefit those of you who struggle to bend over.
Whilst this can in turn reduce the number of your common backyard birds that use it, at least you'd be in a better position to regularly change out the water and clean the bird bath, two the three times a week.
Bird baths on a pedestal are only two to three feet high, so bending over slightly is still called for. But with a ground bird bath, it would require you to fully bend over to lift it up, or indeed attend to it while on your knees.
Bird baths don't need to be elevated but a ground level bird bath doesn't need to be laid flat on the ground either.
I would then suggest using objects around the yard to place the ground bird bath on a higher, more safer position to at least make sure its within your reach.
To summarize
I can assure you now, bird baths of any kind do not need to be elevated off the ground, as you'll sure to see many birds use a bird bath sat on the lawn or patio.
Indeed if you are mostly visited by ground foraging birds, this can see a drop in use of your elevated bird bath as many don't have the agility, or indeed are to large to use a fragile bird bath on a stand.
While ground level birds baths can be used by most birds, those birds that forage from a higher point in nature, prefer a bird bath located off the ground.
Saying all that, in times of need, no bird would be too fussy where or what they use to re-hydrate in.
Elevated bird baths are likely to attract many bird species regardless, providing the bird bath location is out in the open, and seen from above.
Ground birds baths shouldn't remain on the ground if they are not being used, thus to move the bird bath bowl to a more safe and secure elevated point would allow you to find a more successful location in due course.
Birds are sure to use an elevated bird bath more as oppose to a ground level placement, but it can really depend on the types of birds that frequent your yard more often.
With all that, look to your own health by using an elevated bird bath - or indeed locate a ground bird bath higher off the ground - as to avoid bending over if you are unable to.
