Brown Creepers (Certhia americana) are unusual-looking birds. They are relatively small songbirds (about 5 inches (13 cm) in length) that have long, curved claws and a sharp, curved bill. Their mottled bodies cause them to blend in really well with the bark of the trees on which they are usually found. Even when I manage to spot one, they tend to be in motion all of the time as they spiral their way up the trunk of the tree, making them tough to photograph.

Last week at Occoquan Bay National Wildlife Refuge I was thrilled to capture some shots of a Brown Creeper. I was particularly happy that the images show the bird’s distinctive bill and claws. In the middle photo, you can see how the creeper uses its curved bill to poke about in the crevices as it searches for insects, sometimes bracing itself with its stiff tail.

Brown Creepers (Certhia americana) are strange little birds. They crawl upwards on tree trunks and large branches in a spiraling motion, pausing periodically to probe crevices for tiny insects with their slender, downcurved bills—they never seem to perch and they rarely seem to fly.  Their mottled coloration helps them to blend in really well with the bark of the trees, so I rarely see a Brown Creeper, though I suspect they may be fairly common.

On Wednesday as I was walking along a trail at Occoquan Bay National Wildlife Refuge, my eyes detected some moment in a tree just off of the trail. By the time I spotted the bird, which I was able to identify as a Brown Creeper, it was already high up in the tree. Fortunately I was able to track the creeper when it dropped from that tree down to the base of an adjacent tree to begin another upward creep.

I took dozens of photos as the bird circled around the tree and in most of them the bird was blocked or blurred. However, I did manage to get a couple of clear shots. In the first image, you can see the Brown Creeper in action as it investigates a crevice. Note the curve in the bill and the way that it has positioned its large feet for stability. The tail is supposed to be really stiff too and provides additional support.

The second image provides a good look at the long, lanky body of this Brown Creeper. You can see the white underparts of the bird that are usually hidden against the tree trunks. I am fascinated by the patterns in its feathers and the markings on the creeper’s heads and encourage you to click on the image to get a more detailed look at these features.

I love the description of this bird on the Cornell Lab of Ornithology website that cited naturalist W.M. Tyler, who wrote in 1948 the following words:

“The Brown Creeper, as he hitches along the bole of a tree, looks like a fragment of detached bark that is defying the law of gravitation by moving upward over the trunk, and as he flies off to another tree he resembles a little dry leaf blown about by the wind.”

I was delighted last Monday to capture a shot of this energetic little Brown Creeper (Certhia americana) at Occoquan Bay National Wildlife Refuge. These tiny songbirds move upwards around tree trunks and branches in a spiraling motion as they search for insects. Their mottled plumage helps them to blend in with the bark of the trees, which makes them really tough to spot and to photograph.

Can you spot the bird in this photo? Its white underparts help to give away its position, but otherwise the Brown Creeper (Certhia americana) is pretty well camouflaged. I rarely see these little birds (about 5 inches (13 cm) long) because they blend in so well and are constantly in motion, poking and probing as they spiral their way to the top of the trees.

I really like the way that the Cornell Lab of Ornithology describes these small birds—”Brown Creepers are tiny woodland birds with an affinity for the biggest trees they can find. Look for these little, long-tailed scraps of brown and white spiraling up stout trunks and main branches, sometimes passing downward-facing nuthatches along the way. They probe into crevices and pick at loose bark with their slender, downcurved bills, and build their hammock-shaped nests behind peeling flakes of bark. Their piercing calls can make it much easier to find this hard-to-see but common species.”

I spotted the Brown Creeper this past Tuesday at Occoquan Bay National Wildlife Refuge early in the morning when the light had a golden tinge that made everything look particularly beautiful. I tried to track the bird as it made its way up the tree and took quite a few photos. This is one of the few in which I got a relatively clear view of the entire bird, including its stiff tail that it uses for support.

This Brown Creeper (Certhia americana) blended in so perfectly with the tree bark yesterday morning at Occoquan Bay National Wildlife Refuge that I don’t think I would have spotted it if it had not been moving. Brown Creepers are small in size, 4.7-5.5 inches in length (12-14 cm) and 0.2-0.3 ounces in weight (10-15 grams, and are in motion almost continuously, which makes them pretty tough to photograph.

If you click on the photos below, you can see some of the cool details of this little bird, like its large feet that aid stability and its slender, curved bill used to probe for bugs in and under the bark.

Brown Creepers (Certhia americana) are tough to photograph as they spiral their way up tree trunks, so I was thrilled when I managed to get a mostly unobscured shot of one of these little birds on Monday at Occoquan Bay National Wildlife Refuge.

How small are Brown Creepers? According to information on the Cornell Lab of Ornithology website, Brown Creepers are 4.7 to 5.5 inches in length (12 to 14 cm) and weigh 0.2 to 0.3 ounces (5 to 10 grams). For the sake of comparison, the birds that I featured yesterday, Bald Eagles, are 27.9 to 37.8 inches in length (71 to 96 cm) and weigh 105.8 to 222.2 ounces (3000 to 6300 grams).

I was quite excited on Monday at Occoquan Bay National Wildife Refuge when this Brown Creeper (Certhia americana) finally let me get a relatively unobstructed shot of it. I had spent quite a while trying to track it as it climbed up and around several trees in a kind of corkscrew pattern.

In the past I have seen this elusive little bird several times, but as far as I know, this is the first time that I have ever gotten a shot of one. The Brown Creeper moves in a pattern that is not at all like any other bird that I have observed. The Cornell Lab of Ornithology website provides the following description of this behavior:

“The Brown Creeper spends most of its time spiraling up tree trunks in search of insects. It holds its short legs on either side of its body, with the long, curved claws hooking into the bark, and braces itself with its long, stiff tail. Both feet hop at the same time, making the bird’s head duck after each hop. Because of its specialized anatomy, the Brown Creeper rarely climbs downward: once high in a tree, it flies down to begin a new ascent at the base of a nearby tree.”

I am happy with this shot, though I must confess that I get a little dizzy if I look at it too long.
