The Campo Flicker (*Colaptes campestris*) is a striking, ground-dwelling woodpecker native to the grasslands and savannas of central South America. Unlike most woodpeckers that cling to trees, this species is uniquely adapted to an open-country lifestyle, often seen foraging on the ground for ants and termites with a hopping gait. Its general appearance is bold and unmistakable: a golden-yellow head and neck contrast sharply with a black chest bib and a barred, brownish-black back, while a white rump flashes conspicuously in flight. Special features include a long, slightly curved bill for probing soil and a loud, laughing call that echoes across the pampas. During breeding season, pairs nest in earthen banks or termite mounds, carving out cavities rather than tree trunks, further cementing its role as a distinctive specialist of the open plains.

Faits amusants

Despite its name, the Campo Flicker is a highly terrestrial woodpecker, spending most of its time hopping across grasslands on the ground like a robin rather than hammering on tree trunks. It has a uniquely long, slightly curved bill perfectly adapted for digging into ant and termite mounds, and it often uses its sticky, barbed tongue to lap up the insects from deep within the soil. A quirky behavior is its habit of following army ant swarms to snatch up fleeing insects, and it sometimes even engages in "anting," where it deliberately rubs ants on its feathers to use the formic acid as a natural insecticide against parasites.

Habitats et répartition

The Campo Flicker is found across central and eastern South America, with its range extending from Suriname and northern Brazil south through Bolivia, Paraguay, Uruguay, and into central Argentina. Its habitat is strongly tied to open and semi-open landscapes, including natural grasslands, savannas (such as the Cerrado and Pantanal), agricultural fields, pastures, and roadside edges. It avoids dense forests but readily occupies disturbed areas, palm groves, and even urban parks or golf courses where short grass and scattered trees or termite mounds are present, the latter being crucial for nesting.

Comportements & Reproduction

The Campo Flicker is a highly social woodpecker, typically found in small, loose flocks that forage together on the ground for ants and termites. Their social structure is cooperative, especially during the breeding season, where multiple adults may assist in raising young. Mating pairs form monogamous bonds for the season, with courtship involving mutual head-bobbing, wing-flicking, and duetting calls to reinforce pair bonds. They nest in cavities excavated in termite mounds, dead trees, or fence posts, with both sexes sharing the excavation duties. A unique reproductive strategy is their use of termite mounds for nesting, which provides a stable, insulated environment and protection from predators. Clutch sizes range from 3 to 5 white eggs, incubated by both parents for about two weeks. After hatching, chicks are fed by the parents and often by additional helpers from the flock, a cooperative breeding behavior that enhances fledgling survival in open grassland habitats.

Alimentation

The Campo Flicker is primarily an insectivore, with a diet heavily centered on ants and termites, which it extracts by probing into the ground, rotting logs, and ant mounds with its long, sticky tongue. Unlike many woodpeckers that drill into wood, this species is largely terrestrial, foraging on the ground in open grasslands and savannas, often in small flocks. An interesting fact is that it will also consume seeds and fruits, particularly during the dry season when insects are scarce, and it has been observed raiding the nests of ground-dwelling wasps to eat the larvae.

Couleurs

The Campo Flicker has a brownish-tan body with bold black barring across the back, wings, and tail, while its head and neck are pale yellow with a black crown and a distinctive red crescent on the nape. Its breast features a large black crescent, and the male has a red malar stripe. The underparts are whitish with black spots, and the yellow underwings flash in flight, serving as a disruptive pattern against the open grasslands it inhabits.
