Unlike true guans, it is the sole member of its genus and is most notable for the vivid red, horn-like projection atop its head\u2014a fleshy, erectile structure unique among cracids. Its general appearance is robust and turkey-like, with glossy black plumage, a white belly, and a long, broad tail tipped in white, while its powerful legs and strong beak aid in foraging for fruits and leaves. A special feature is its unusual, low-frequency booming call, which resonates through the misty highlands, and its role as a vital seed disperser for the endangered cloud forest ecosystem.","animal_habitat":"The Horned Guan is endemic to the highlands of southern Mexico and western Guatemala, with its range restricted to the Sierra Madre de Chiapas and the volcanic cordillera of Guatemala. It inhabits humid montane and cloud forests, typically between 1,800 and 3,200 meters in elevation, where it prefers steep, forested slopes with dense understory and abundant epiphytes. These environments are characterized by persistent mist, high rainfall, and cooler temperatures, and the guan relies on intact forest cover for foraging on fruits and leaves, as well as for nesting in tree cavities or dense foliage.","animal_behavior_and_reproduction":"The Horned Guan is primarily solitary or found in pairs, with a social structure centered on a monogamous bond. During the breeding season, which typically occurs from March to June, the male performs a display that involves raising its unique red horn and inflating its throat sac while emitting low, resonant calls to attract a female. After mating, the female constructs a simple, bulky nest of leaves and twigs in a tree cavity or fork, usually high above the forest floor. She lays a clutch of one to two eggs, and incubation, which lasts around 30 to 35 days, is carried out solely by the female. The chicks are precocial, leaving the nest shortly after hatching to follow the parents, but they are still fed and guarded for several months. A unique reproductive strategy is the species\u2019 extremely low reproductive rate, with pairs often successfully raising only one chick every two years, which makes them highly vulnerable to population decline.","diet":"The Horned Guan is primarily frugivorous, with its diet consisting largely of fallen fruits and berries from the forest floor, particularly favoring avocados from wild laurel trees (Ocotea species), along with figs and other soft fruits. Interestingly, while fruit makes up the bulk of its intake, it also consumes a significant amount of leaves, buds, and tender shoots, especially during seasons when fruit is scarce. A unique dietary behavior is its occasional consumption of small vertebrates, such as lizards or frogs, and insects, making it more omnivorous than many other cracids. Additionally, the bird plays a vital ecological role as a seed disperser; its powerful gizzard helps break down hard seeds, which are then deposited across its cloud forest habitat, aiding in forest regeneration.","colors":"The Horned Guan is predominantly glossy black with a white belly, a red horn-like casque on its crown, and a white-tipped black tail. Its chest and neck display fine white streaking, while the bare facial skin is red. This coloration provides camouflage in the dappled light of its cloud forest habitat, with the black body blending into shadows and the white belly breaking up its outline.","fun_facts":"Despite its name, the horned guan\u2019s most peculiar feature isn\u2019t actually a horn\u2014it\u2019s a single, fleshy, bright-red wattle that dangles from the top of its head like a deflated party balloon, which the bird can inflate with blood during displays. It is the only surviving member of its genus, making it a living fossil that diverged from other guans millions of years ago. Quirkily, it has a habit of sunbathing with its wings spread wide on high-altitude cloud forest branches, possibly to warm up after chilly mountain nights or to dry out its feathers from the constant mist. Its diet includes a bizarre twist: it regularly eats clay from riverbanks, a behavior thought to neutralize toxins in unripe fruits or aid digestion.","conservation_status_&_efforts":"Listed as Endangered on the IUCN Red List, the Horned Guan has a decreasing population estimated at fewer than 1,000 mature individuals, with a very small and fragmented range in the cloud forests of Guatemala and southern Mexico. Primary threats include ongoing habitat loss from agricultural expansion, livestock grazing, and logging, as well as hunting pressure for food and trade. Specific conservation measures include the establishment and management of protected areas like the Sierra de las Minas Biosphere Reserve in Guatemala, community-based patrols to reduce poaching, and research initiatives to monitor population dynamics and nesting success. Additionally, captive breeding programs exist in zoos, though reintroduction efforts remain limited due to the species\u2019 specialized habitat requirements.","endemic":true,"migratory":false,"nocturnal":false,"conservation_status":"Endangered","ebird_link":{"url":"https:\/\/ebird.org\/species\/horgua1","title":"View on Ebird","target":"_blank"},"animal_related_page":{"url":"https:\/\/animalia.bio\/horned-guan","title":"View on Animalia","target":"_blank"},"fauna_family":"Cracidae","fauna_known_nicknames":"Pav\u00f3n Cornudo, Horned Curassow","fauna_average_length":"73\u201385 cm \/ 29\u201333 in","fauna_average_weight":"2.1\u20132.7 kg \/ 4.6\u20136.0 lb","fauna_wingspan":"N\/A","fauna_key_physical_feature":"Single bright red horn-like casque on top of the head","fauna_primary_diet":"Primarily Frugivore","fauna_geographical_range":"Sierra Madre de Chiapas (Mexico) and western Guatemala","fauna_preferred_habitat":"Humid montane cloud forest at elevations of 1,800\u20133,350 m","fauna_social_structure":"Solitary or in Pairs","fauna_breeding_site":"Tree nests of twigs and leaves, typically in the forest canopy","fauna_conservation_status":"Endangered (EN)","fauna_population_trend":"Decreasing","fauna_spanish_name":"Pav\u00f3n cornudo","fauna_french_name":""},"_links":{"self":[{"href":"https:\/\/remote-expeditions.com\/fr\/wp-json\/wp\/v2\/fauna\/291434","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\/346799"}],"wp:attachment":[{"href":"https:\/\/remote-expeditions.com\/fr\/wp-json\/wp\/v2\/media?parent=291434"}],"wp:term":[{"taxonomy":"collection","embeddable":true,"href":"https:\/\/remote-expeditions.com\/fr\/wp-json\/wp\/v2\/collection?post=291434"},{"taxonomy":"country","embeddable":true,"href":"https:\/\/remote-expeditions.com\/fr\/wp-json\/wp\/v2\/country?post=291434"},{"taxonomy":"fauna-group","embeddable":true,"href":"https:\/\/remote-expeditions.com\/fr\/wp-json\/wp\/v2\/fauna-group?post=291434"},{"taxonomy":"fauna-type","embeddable":true,"href":"https:\/\/remote-expeditions.com\/fr\/wp-json\/wp\/v2\/fauna-type?post=291434"},{"taxonomy":"star-rating","embeddable":true,"href":"https:\/\/remote-expeditions.com\/fr\/wp-json\/wp\/v2\/star-rating?post=291434"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
