Ovenbird

The ovenbird is kind of punk rock. It wears a jacket of olive feathers and has an orange mohawk-like stripe down the middle of its crown, lined in black on either side. When it gets agitated, it can raise this stripe to form a crest, and yell down from a high branch, “Tea-cher, tea-cher, tea-cher!” The female ovenbird is not satisfied to build an ordinary nest. Instead, she creates something that looks an awful lot like a primitive pizza oven on the forest floor, then proceeds to dump leaves and twigs on it for camouflage. This is no ordinary bird.

Incredible Ovenbird Facts

• Female ovenbirds build nests that look like ovens. That’s where they got their name.
• Ovenbirds migrate from as far north as Canada to winter as far south as northern South America.
• Robert Frost once wrote a poem about this bird.
• Males of this species sing a lot, but females rarely sing.
• Female ovenbirds will feign an injury to lure predators away from the nest.
• Ovenbirds have a lot of potential nest predators, from bears to chipmunks.

Where to Find the Ovenbird

The ovenbird is a migratory warbler species. It can be found in the United States and Canada during its breeding season. The breeding range extends as far south as the Chattahoochee-Oconee National Forests in Georgia to the Ouachita National Forest in Arkansas. From August through October, the ovenbird flies south to Mexico, Central America, the Caribbean, and even far northern South America. It returns from its winter habitat in the spring, from March through May.

This bird lives in forests with thick canopies and an abundance of leaf litter. It prefers to be in wooded areas with relatively little undergrowth. It makes its nest on the forest floor, in a small clearing among fallen leaves, because that is where it forages for food. Ovenbirds are not usually found in open areas, although they do not seem to be averse to nesting near the edges of forests. They probably would not live too close to people, unless those people happened to also live in the woods.

Ovenbird Scientific Name

The scientific name of the ovenbird is Seiurus aurocapilla. This bird is the only species in its genus. It was originally named Motacilla aurocapilla by Linnaeus in 1766. Aurocapilla means golden-haired in Latin; therefore, it is likely a reference to the orange stripe that adorns its crown. The common name, ovenbird, is a reference to the bird’s oven-shaped nest.

The ovenbird should not be confused with the red ovenbird, Rufous hornero, which is native to South America and is the national bird of both Argentina and Uruguay. Although both were named for their oven-shaped nests, S. aurocapilla belongs in the Parulidae family, whereas R. hornero belongs in the Furnariidae family.

Ovenbird Appearance

The ovenbird is a large warbler. It is smaller than most sparrows, reaching a length of about 4.3 to 6 inches. It has a wingspan between about 7.5 and 10.2 inches. Its weight can vary between about 14 and 28.8 g, or roughly half an ounce to an ounce. It has slender pink legs and feet, and its short, pointed bill is black on top and pinkish on the bottom.

Ovenbirds are not sexually dimorphic; therefore, the males and females look the same. They are olive brown on their upper parts, with more of an olive green tint on their flanks. They have a white underside, with lots of black streaks on their breasts. Their tail is relatively long and usually tilted up as they walk on the ground and forage.

The ovenbird’s face is green, with a black stripe running from the base of its beak down its white neck on each side. It also has a white ring around its eyes. An orange stripe, bordered by black stripes on either side, crowns the bird’s head like a mohawk. The bird can raise this stripe into a crest, which is sometimes used in a defensive show.   

Ovenbird Behavior

The ovenbird is often recognized by its call. The call is described as a rapid “tea-cher, tea-cher, tea-cher,” which is repeated several times per second. Males sing often, from perches high in the trees or on the ground, to declare their territory and to find a mate. Females, however, rarely sing, which makes them harder to spot.

The ovenbird walks on the ground and does not hop like other songbirds, as it forages for food. It recognizes locations that are good sources of food and returns to them.

Ovenbirds are territorial, both as single birds and in pairs. They stick mainly to higher ground within their breeding range, leaving lower-lying areas to other warblers. They are defensive of their nests. When other birds enter their territory, ovenbirds may engage in defensive displays and loud calling.

Diet

Ovenbirds forage for food in the leaf litter on the forest floor. They eat insects, both adult and larval, and other invertebrates, including spiders, snails, and worms. Sometimes these birds will also eat seeds and berries, particularly during winter. Both females and males feed the juveniles, usually with small insects and insect larvae.

Ovenbird Reproduction

Male ovenbirds sing loudly to attract a mate. These birds are monogamous and sometimes stay together for life. Once a male has successfully found his mate, the business of reproduction begins.

The ovenbird was named for its unusual nest. The female bird builds the nest on the ground, in a small clearing. The nest is made of twigs, leaves, grass, bark, and other fibers. She fashions it in the shape of a dome, complete with a roof and an entrance on the side, and lines it with animal hair. When she is finished, she drops leaves and twigs on top of it to disguise its presence. The nest resembles a primitive outdoor oven.

Once the nest is complete, the female lays between 3 to 6 eggs. She incubates the eggs alone, waiting 11 to 14 days for her offspring to hatch. After that, for the next 7 to 10 days, the juveniles stay in the nest. They begin to wander around close to the nest after that, but they are not independent for another 10 to 20 days.

Ovenbirds typically have only one brood per year, but can have up to three in response to external pressures. The birds do not usually reuse their nests, but once they are finished with them, other creatures of the forest may call them home.

Predators

Researchers studying nest behavior in ovenbirds identified a number of potential nest predators. These include snakes, squirrels, chipmunks, foxes, skunks, bears, raccoons, white-tailed deer, hawks, crows, and blue jays.

Owls, hawks, and domestic cats may also prey on adult ovenbirds. Often, these birds will stay very still to try to avoid being detected by a predator. Sometimes the males will engage in defensive posturing, including raising their crest, raising their tail, and dropping their wings while making a lot of noise. Females may feign an injury to try to draw a predator away from their nest. Both sexes may escape to a high branch if threatened.

Other Threats

One of the problems ovenbirds face is a nest parasite called the brown-headed cowbird. This lazy bird is known for laying its eggs in the nests of songbirds and then taking off, leaving the unsuspecting parents to raise its youngsters as their own. Nest parasitism by the brown-headed cowbird caused the black-capped vireo to become endangered in 1987. Fortunately for the ovenbird, its chicks have a shorter incubation period than the cowbirds, so the interlopers are not always successful.

Ovenbirds face several other threats as migratory birds. For instance, they are prone to window strikes, especially on office buildings and high rises. They have also died in encounters with cruise ships on the way to their Caribbean winter grounds.

Scientists believe the biggest threat to the ovenbird is forest fragmentation. As trees are taken down, whether for logging or development, the habitat of these forest-dwelling birds is disrupted. Disturbances to the winter habitat can be just as damaging as those in the summer breeding grounds.

Lifespan of the Ovenbird

Researchers completed a ten-year study of ovenbirds in Michigan. They estimated that the average lifespan of the birds was approximately 2.7 years. However, the longest living individual known to date was a banded bird that lived to be 11 years old.  

The Ovenbird in Literature

The great American poet, Robert Frost, wrote a poem about the ovenbird. Interestingly, the sonnet is thought to be a metaphor for the passage of time, with the ovenbird representing the author himself.
