Clad in dark, soot-colored plumage that reflects a subtle metallic bronze or bottle-green sheen in the sunlight, its most striking feature is the namesake patch of vibrant, featherless skin surrounding its eyes and extending to the base of its bill. This bare facial skin ranges in color from pale pink to a deep, carmine red, providing a vivid contrast against its long, slender, decurved bill which it uses to probe the mud for aquatic invertebrates. Unlike many of its more gregarious relatives, the Bare-faced Ibis is often seen in smaller, more intimate groups, navigating flooded grasslands with a graceful, deliberate gait that highlights its unique blend of understated elegance and specialized evolutionary adaptations.","animal_habitat":"This species occupies a variety of open wetland environments, including marshes, swamps, and seasonally flooded grasslands or savannas. It is frequently observed foraging in shallow water or soft mud, often utilizing human-altered landscapes such as rice paddies and damp pastures. While it primarily favors freshwater ecosystems, it can also be found in brackish areas and along the muddy margins of slow-moving rivers and lakes.\n\nThe geographical range is concentrated in two primary regions of South America. The northern population inhabits parts of Colombia, Venezuela, and the Guianas, while the southern population covers a vast territory encompassing eastern Bolivia, central and southern Brazil, Paraguay, Uruguay, and northern Argentina. Within these regions, it is particularly abundant in large wetland systems like the Llanos and the Pantanal.","animal_behavior_and_reproduction":"Highly social and gregarious, these birds typically forage and roost in small to large flocks, often intermingling with other wading species. They are diurnal and employ a tactile probing technique to find prey in soft mud, frequently maintaining group cohesion while feeding. During the breeding season, which usually coincides with the arrival of the rains, they form monogamous pairs and congregate in nesting colonies. These colonies are often established in trees or bushes overhanging water, providing a strategic defense against land-based predators.\n\nThe reproductive process involves both parents, who cooperate to build a platform nest of sticks and reeds. Females typically lay two to three eggs, and both adults share incubation duties and the subsequent feeding of the chicks via regurgitation. This collective nesting strategy enhances the survival rate of the offspring through increased vigilance and shared defense. Their social structure remains tight-knit throughout the year, as they often return to the same communal roosting sites every evening.","diet":"The Bare-faced Ibis maintains a primarily carnivorous diet, focusing on a variety of small invertebrates found within its wetland habitats. Using its long, decurved bill, it probes deeply into soft mud and shallow water to extract aquatic insects, larvae, earthworms, crustaceans, and snails. An interesting aspect of its feeding strategy is its reliance on tactile sensitivity; the tip of its bill is equipped with specialized nerve endings that allow it to detect prey by touch rather than sight, a method known as tactile foraging. Additionally, these birds are often observed in communal groups or following grazing livestock, taking advantage of the insects and small organisms disturbed by the movement of larger animals. While its diet is dominated by invertebrates, it may occasionally supplement its intake with small vertebrates such as frogs or tiny fish when the opportunity arises.","colors":"The Bare-faced Ibis features uniform dark brownish-black plumage with a subtle greenish or purplish iridescent sheen. Its most distinctive characteristic is the extensive patch of bare, reddish-pink skin on the face, which contrasts with a long, decurved bill and legs that range from reddish-brown to pink. This dark, somber coloration provides effective camouflage when the bird forages in the shadows of dense wetland vegetation.","fun_facts":"The Bare-faced Ibis possesses a specialized bill tip packed with nerve endings, enabling it to \"see\" prey through touch while probing deep into thick mud. During the breeding season, its namesake bare facial patch flushes an intense, brilliant red to signal health and vitality to potential mates. These birds are also clever opportunists, often following livestock to snatch up insects flushed out by the movement of heavy hooves. Perhaps most peculiar is their courtship ritual, which involves a series of rapid \"bill-snapping\" sounds created by clattering their mandibles together in a rhythmic, percussive display.","conservation_status_&_efforts":"The Bare-faced Ibis is currently categorized as Least Concern by the IUCN Red List due to its expansive range across South America and a population trend that appears to be stable or increasing. This species exhibits remarkable adaptability, frequently colonizing human-altered environments such as rice paddies, cattle pastures, and suburban parks. Because it is not considered globally threatened and maintains a large, continuous population, it does not currently require intensive species-specific management or recovery programs.\n\nPrimary threats are localized rather than systemic, involving the drainage of wetlands for urban development and the potential impact of agricultural chemicals on its aquatic food supply. Consequently, conservation efforts are largely indirect, focused on the general preservation of South American wetland ecosystems and the enforcement of environmental regulations within protected areas. These broad-scale habitat protection measures, rather than targeted interventions, are sufficient to sustain the species' population at this time.","endemic":false,"conservation_status":"Least Concern","ebird_link":{"url":"https:\/\/ebird.org\/species\/bafibi1","title":"View on Ebird","target":"_blank"},"animal_related_page":{"url":"https:\/\/animalia.bio\/bare-faced-ibis","title":"View on Animalia","target":"_blank"},"fauna_family":"Threskiornithidae","fauna_known_nicknames":"Whispering Ibis","fauna_average_length":"45\u201355 cm \/ 18\u201322 in","fauna_average_weight":"500\u2013600 g \/ 1.1\u20131.3 lb","fauna_wingspan":"80\u201395 cm \/ 31\u201337 in","fauna_key_physical_feature":"Bare, reddish-pink facial skin and long, decurved bill","fauna_primary_diet":"Omnivore (primarily insects and aquatic invertebrates)","fauna_geographical_range":"South America (Colombia and Venezuela south to Argentina and Uruguay)","fauna_preferred_habitat":"Freshwater wetlands, marshes, flooded pastures, and wet savannas","fauna_social_structure":"Highly social; typically found in flocks","fauna_breeding_site":"Colonial nests in trees, shrubs, or reeds near water","fauna_conservation_status":"Least Concern (LC)","fauna_population_trend":"Stable","fauna_spanish_name":"Ibis de cara roja","fauna_french_name":""},"_links":{"self":[{"href":"https:\/\/remote-expeditions.com\/fr\/wp-json\/wp\/v2\/fauna\/247194","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/remote-expeditions.com\/fr\/wp-json\/wp\/v2\/fauna"}],"about":[{"href":"https:\/\/remote-expeditions.com\/fr\/wp-json\/wp\/v2\/types\/fauna"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/remote-expeditions.com\/fr\/wp-json\/wp\/v2\/media\/247080"}],"wp:attachment":[{"href":"https:\/\/remote-expeditions.com\/fr\/wp-json\/wp\/v2\/media?parent=247194"}],"wp:term":[{"taxonomy":"collection","embeddable":true,"href":"https:\/\/remote-expeditions.com\/fr\/wp-json\/wp\/v2\/collection?post=247194"},{"taxonomy":"country","embeddable":true,"href":"https:\/\/remote-expeditions.com\/fr\/wp-json\/wp\/v2\/country?post=247194"},{"taxonomy":"fauna-group","embeddable":true,"href":"https:\/\/remote-expeditions.com\/fr\/wp-json\/wp\/v2\/fauna-group?post=247194"},{"taxonomy":"fauna-type","embeddable":true,"href":"https:\/\/remote-expeditions.com\/fr\/wp-json\/wp\/v2\/fauna-type?post=247194"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
