Evolution and systematics
The ovenbirds (Furnariidae) are a family of songbirds within the extremely diverse order of perching birds (Passeriformes). They are most closely related to the woodcreepers (Dendrocolaptidae), ant thrushes (Formicariidae), cotingas (Cotingidae), manakins (Pipridae), and tyrant flycatchers (Tyrannidae). Some avian taxonomists consider the wood-creepers to be a subfamily of the Furnariidae, naming them as Dendrocolapinae. The family is divided into three subfamilies. The true ovenbirds (Furnariinae) are about 40 species of long-legged songbirds found predominantly in southern South America that nest on the ground or use moist soil for nest-building. The bushcreepers (Synallaxeinae) are 95 species of small birds found mainly in tropical South America, often with a fringed or long tail; they build a ball-like nest. The leafcreepers (Philydorinae) are 84 species found predominantly in tropical America that forage on tree-trunks or in foliage and usually build their nest in an excavated tunnel.
Physical characteristics
Species in the ovenbird family have a range of body length of 5–11 in (13–28 cm). Their wings are relatively short, and may be rounded or pointed at the tips. The legs and feet are of medium length, and the front toes are joined at the base. The bill is slender, short to long, and pointed. They usually have a brownish, relatively inconspicuous coloration on the back, and range from light to brown-and-white speckled or streaked on the belly. Many species have a white throat. They have a light stripe over the eye, known as a superciliary line. The wing bands are often brownish red or white. The sexes are usually similarly colored.
Distribution
Species in the ovenbird family range from central Mexico to Patagonia in southern South America.
Habitat
Ovenbirds are non-migratory birds that inhabit forests of various kinds as well as brushlands, pampas (grasslands), alpine habitats, and semi-desert.
Behavior
Ovenbirds may occur as solitary individuals or as a breeding pair, or sometimes in small groups. Some ovenbirds occur with other birds in mixed-species foraging flocks. They occur on the ground and in trees; the ground-foraging species tend to walk and hop, while some of the arboreal species forage acrobatically within foliage and finer branches, and others on tree-trunks. The flight of some species is rather weak, but it is strong in others, although not over a long distance. The calls are harsh and scolding, and the song consists of series of whistles and trills.
Feeding ecology and diet
Ovenbirds feed mostly on insects, spiders, and other invertebrates. Some species also eat small seeds. They forage among litter on the ground or in foliage and on bark and epiphytes of shrubs and trees.
Reproductive biology
The nests of ovenbird species are extremely variable in their shape and mode of construction. Many species build a loose nest of plant fibers inside of a natural cavity in a tree or among rocks. The birds that are actually called "ovenbirds" are species in the genus Furnarius; these species are also called horneros, Spanish for "a baker of bread." Their nest is built by both members of a breeding pair and is made of thousands of lumps of moist clay, each about 0.1 oz (3 g) in weight and carried to the nest-site in the bill. Initially, a nest-base of varying thickness is built, depending on the nature of the supporting structure beneath, which is often a stout tree branch, but may also be on the ground. Next, the pair of birds builds the outer walls, which are then joined to form a roof, thus creating a structure that superficially resembles an oven. An entrance hole is left on one of the sides to permit access to the nest cavity, which is lined with fine fibers of grass and other plant tissues. Nests typically weigh about 10 lb (4 kg), but they can weigh as much as 15 lb (6.8 kg). One pair of ovenbirds may work on constructing as many as four nests at a time, either working together on all of them or each bird making only one. At the beginning of the egg-laying season, however, usually only two nests are completed and ready for use for breeding or roosting. Often other species of birds, such as swallows, use abandoned ovenbird nests for their own breeding.
The miners (Geositta) dig tunnels 3–10 ft long (1–3 m) into an earthen bank or cliff. Spine-tails (Synallaxis) build small, spherical, hanging nests in trees, which are entered through a hole from below. Canasteros (Asthenes) build a huge, roughly spherical nest about 14 ft (4 m) high in a tree. The nest is about 15–17 in in diameter (40 cm) and is entered by a hole on the side. Thornbirds (Phacellodomus) build the largest nests, which can be 3 ft (1 m) high, spherical, and made of twigs. It often contains several chambers, all of which are entered from below.
Species in the ovenbird family lay two to six eggs that are usually colored white, or sometimes blue or greenish. Both parents share in the incubation of the eggs and in the care of the nestlings and fledglings.
Conservation status
The IUCN lists 45 species of ovenbirds as being at risk. Critically Endangered species are the royal cinclodes (Cinclodes
aricomae) of Bolivia and Peru, the Alagoas foliage-gleaner (Philydor novaesi) of Brazil, and the plain spinetail (Synallaxis infuscata) of Brazil. Endangered species are the Cipo castanero (Asthenes luizae) of Brazil, the Bolivian spinetail (Cranioleuca henricae) of Bolivia, the white-browed tit-spinetail (Leptasthenura xenothorax) of Peru, the hoary-throated spinetail (S. kollari) of Brazil and Guyana, the blackish-headed spinetail (S. tithys) of Ecuador and Peru, the Bahia spinetail (S. whitneyi) of Brazil, the russet-bellied spinetail (S. zimmeri) of Peru, the russet-mantled softtail (Thripophaga berlepschi) of Peru, and the striated softtail (T. macroura) of Brazil. Most of the designated species at-risk have declined in range and abundance because of the conversion of their habitat into agricultural or residential land-uses, or habitat degradation associated with timber harvesting or other disturbances. These same sorts of stressors are also affecting many other species in the family and are causing them to decline in range and abundance, but not yet to the degree that they are considered to be at-risk.
Significance to humans
The rufous hornero (Furnarius rufus) is the national bird of Argentina, in popular recognition of its bold and jaunty demeanor; thus, it is of some cultural significance. Other than this species, members of the ovenbird family are not of much direct importance to humans. They are an interesting and diverse group of birds, however, and viewings of them are widely sought by birdwatchers and other naturalists, resulting in local economic benefits through ecotourism.
