Furnarius rufus (Gmelin, 1788) | |
The Rufous Hornero (Furnarius rufus) is a medium-sized ovenbird in the family Furnariidae It occurs in eastern South America, and is the national bird in Argentina and Uruguay. Also known as the Red Ovenbird, it is common in savannas, second-growth scrub, pastures and agricultural land and is synanthropic. Its range includes southeastern and southern Brazil, Bolivia, Paraguay, Uruguay and northern and central Argentina, extending as far south as northern Patagonia. The species is most closely related to the Crested Hornero of Paraguay and Argentina. There are four accepted subspecies.
The Rufous Hornero is medium-sized with a square tail and very slightly decurved bill. The plumage is overall reddish brown with a dull brown crown and a whitish throat. Sexes are alike and juvenile birds are slightly paler below (probably because they are cleaner). Rufous Horneros feed on insects and other arthropods obtained by foraging on the ground while walking. They sometimes feed on scraps such as bread crumbs.[2] Songs in the Rufous Hornero are sexually distinct. The rapid trill that is usually heard as part of the duet is faster in the male, slower in the female, and both beat their wings at their sides while singing and the wings beat at the same rate as their trill. Thus, while watching an observer may identify the sex by how fast their wings beat while singing.
Predators of adult and young Rufous Horneros include birds of prey such as the Black-chested Buzzard-Eagle Buteo melanoleucus,[3] small mammals, domestic cats, and a number of species of snakes and possibly lizards.[4] However, its covered nest probably reduces predation risk.
