Brown Creepers and Nuthatches share similar physical traits and behaviors, so it can be easy to confuse them.
Both bird species are commonly found in the eastern United States and are frequently encountered by birdwatchers.
But there are ways to tell them apart if you want to enhance your bird watching experience and feel confident in your ability to identify these birds.
If you’re short on time, here are 3 key differences that make it easier to tell apart the Brown Creeper vs Nuthatch:
Brown Creepers –
- Spiral up tree trunks and main branches
- Have longer tails that they use for support
- Have streaky brown and white plumage
Nuthatches –
- Usually move down tree trunks
- Have shorter tails
- Are more grayish in color
Brown Creeper vs Nuthatch: Key Identifiers
The Brown Creeper, known scientifically as Certhia americana, is a tiny woodland bird often found spiraling up tree trunks.
Nuthatches are another group of tree-climbing birds consisting of four species: the white-breasted nuthatch, red-breasted nuthatch, brown-headed nuthatch, and pygmy nuthatch.
And while they share some similarities with Brown Creepers in habitat, food, nesting, and foraging behaviors, they have distinct physical features and tree-climbing patterns.
Brown Creepers have mottled brown plumage, white bellies, and quite long tails relative to the length of their bodies.
Nuthatches, however, are characterized by shorter tails, grayish back plumage, and a lack of streaky brown back feathers, making them look markedly different from Brown Creepers(source).
These are the most significant visual markers of these different bird species. But pay attention to their movements, too.
You’ll notice that the Brown Creepers likes to climb upwards around tree trunks and branches in a spiral pattern.
They will occasionally cross paths in their habitats with Nuthatches, which typically move downwards on tree trunks.
However, both birds can be seen hanging upside down while they forage for food. But the way they climb up and down trees is unique.

Physical Differences
Brown Creeper Characteristics
The Brown Creeper is a tiny, woodland bird that sports a long tail and measures around 4-5 inches in length.
It has a wingspan of approximately 7-8 inches and weighs roughly 0.3-0.4 ounces.
This bird’s feathers are tailored for blending into its surroundings, enhancing its ability to remain inconspicuous. The color pattern on its back is a mix of white and streaky brown, giving it excellent camouflage on tree trunks.
Meanwhile, its tail is relatively long, helping it maintain balance as it creeps up trees.
The Brown Creeper also has a characteristic slender, down-curved bill, specifically designed for probing into crevices and picking at loose bark.
Nuthatch Characteristics
Nuthatches, such as the White-breasted Nuthatch and Brown-headed Nuthatch, are North American sparrow-sized birds measuring around 4.5-5.5 inches in length, with a wingspan of approximately 8-11 inches.
They weigh 0.4-1.2 ounces and possess a distinctive gray color on their backs, contrasting with the streaky brown camouflage of Brown Creepers.
It’s also noticeable how much shorter the Nuthatches’ tails are—and they don’t lean on them for support like Brown Creepers do2.
The bill of the Nuthatch is also quite different from the Brown Creeper’s. It doesn’t curve downward like the Brown Creeper’s, and it often appears sharper and more robust.
As you can see, both Brown Creepers and Nuthatches have their unique physical characteristics that aid them in their specific environments.
Although they might appear similar at first glance, their color patterns, tail lengths, and bills set them apart from one another.

Habitat and Distribution
The Brown Creeper and the Nuthatch have quite distinct habitats and distributions.
Brown Creepers are primarily found in mature forests with mixed deciduous and coniferous trees. They are known to prefer large trees, often choosing conifers with textured bark to help them blend in.
Their habitat stretches throughout much of the United States, including the eastern, western, and parts of the northern regions.
For these small birds, old-growth habitats are their favored environments.
For Nuthatches, they inhabit various types of forests depending on the species.
The White-breasted Nuthatch, for example, is found in deciduous woodlands and oak forests across the United States.
Red-breasted Nuthatches prefer coniferous trees, while the Pygmy Nuthatch favors pine forests in the western region, especially in states like California and Arizona.
Brown-headed Nuthatches are relatively exclusive to the southeastern U.S. pine forests.
To sum up: Brown Creepers are widely distributed across North American forests, while Nuthatches have more specialized habitat preferences, with different species occupying distinct forest types.
Foraging and Diet
Brown Creepers are experts at climbing tree trunks and searching for insects and spiders in the bark. They use their long, stiff tails as support while they spiral upwards, probing in crevices with slender, downcurved bills to find their prey.
Their brown and white streaked camouflage allows them to remain nearly undetectable as they hunt for food.
With their downcurved bills, Brown Creepers probe into crevices and pick at loose bark, searching for insects and other small morsels to eat1.
As for what they eat, they mostly feed on small insects, caterpillars, and eggs hidden under the bark1.
On the other hand, Nuthatches typically walk down tree trunks—not up like Brown Creepers2.
When it comes to foraging, Nuthatches typically feed on trunks and large limbs of pines, as well as higher branches and twigs3.
Their shorter tails do not provide support when climbing, yet their strong legs and toes help them cling to the bark.
And while Brown Creepers and Nuthatches primarily feed on insects, Nuthatches have a more diverse diet.
In their search for food, Nuthatches pry off bark pieces and catch flying insects in the air3. These birds also feed on seeds, storing them in bark crevices for later consumption3.
This interesting foraging behavior allows Nuthatches to maintain a steady food supply throughout various seasons, including migration periods.
Reproduction and Nesting
When it comes to reproduction and nesting, both the Brown Creeper and Nuthatches exhibit unique behaviors.
Brown Creepers typically build their nests behind peeling tree barks or in other natural crevices, giving them protection from predators.
These nests are shaped like hammocks and made of various materials, such as twigs, moss, bark, and feathers.
Comparatively, Nuthatches prefer to create their own nest holes in tree trunks, or they may also use pre-existing cavities or rarely, nest boxes.
Nesting season usually starts in April, with both bird species actively searching for the right spot to lay their eggs.
The Brown Creeper’s nest site is often located high in the trees, while Nuthatches may choose lower elevations depending on the species. For example, the Brown-headed Nuthatch can be found nesting closer to the ground.
During the incubation period, female Brown Creepers and Nuthatches are responsible for keeping the eggs warm, while the respective male partners help provide food.
The incubation period varies slightly for different Brown Creepers, but it generally lasts for about 12-14 days. Nuthatches’ incubation period is similar, usually spanning around two weeks.
Brown Creepers rely on a diet of insects, such as beetles, during breeding season, while Nuthatches consume insects, seeds, or a mix of both. Nuthatches are also known to be quite social, typically forming small flocks, especially during the winter months.
Songs and Calls
The songs and calls of Brown Creepers and Nuthatches may seem similar at first, but they differ in several ways.
Brown Creepers are known for their high-pitched warble. Their thin, faint songs are quieter than Nuthatches’, and in fact can be difficult to hear.
These birds have a soft and musical call, often described as a series of “tsee” notes that can be challenging to hear from a distance.
This delicate sound is one way birdwatchers and Audubon enthusiasts can identify the presence of a Brown Creeper in their vicinity.
In contrast, Nuthatches have a more powerful and easily heard call. They produce a rapid series of “yank” or “hank” sounds that are often likened to a small horn or a child’s noisemaker.
The most common Nuthatch in the eastern United States, the White-breasted Nuthatch, is known for its nasal and repetitive call.
Conservation and Threats
The Brown Creeper and the Nuthatch have unique conservation statuses, habitats, and threats they face.
Both species are known to make their homes in a variety of wooded areas, with Brown Creepers primarily nesting in trees’ crevices and a preference for feeding on insects and spiders found in bark (source).
In contrast, Nuthatches tend to inhabit loblolly, longleaf, shortleaf, and pine-oak forests, with the Brown-headed Nuthatch having a population of around 1.4 million that is currently decreasing (source).
Conservation efforts for these birds vary widely. Organizations such as the American Bird Conservancy and Audubon regularly monitor the well-being and populations of these species.
Through state programs and membership initiatives, they aim to protect and preserve the habitats vital to these birds’ survival.
Audubon centers and chapters across the country actively participate in promoting conservation efforts and often provide important news on threats facing these birds.
Habitat loss is a significant threat to both Brown Creepers and Nuthatches.
The Brown-headed Nuthatch, in particular, relies heavily on pine-forest habitats, which have seen a decline due to urbanization and changes in land use.
Additionally, both species face threats from predators such as snakes, cats, and other birds that prey upon their eggs and young (source).
