The male is a living jewel, characterized by a brilliant violet-blue crown and belly that contrast sharply with a shimmering emerald-green throat and a deeply forked, steel-blue tail. While females are more subtly colored with pale grey underparts, both sexes are remarkable for their \"trap-lining\" feeding strategy, where they follow a precise, repeated circuit to visit specific nectar-rich flowers. Highly territorial and spirited, this vibrant bird is often seen aggressively defending its feeding patches or darting through the forest understory with incredible agility, making it one of the most captivating sights of the tropical canopy.","animal_habitat":"This species primarily inhabits humid evergreen forests, montane forests, and tall secondary growth, often favoring forest edges and shaded plantations. It is most commonly found in the understory and mid-story layers, though it also frequents semi-open areas and garden clearings where floral resources are plentiful.\n\nIts geographical range extends from Guatemala and Belize through Central America to the northern and western regions of South America, including Colombia, western Venezuela, Ecuador, and Peru. It typically occupies elevations from sea level up to approximately 2,500 meters, showing a strong preference for humid foothills and subtropical zones.","animal_behavior_and_reproduction":"These hummingbirds are highly territorial and aggressive, with males vigorously defending high-quality nectar sources against competitors. Outside of brief mating encounters, they are solitary animals. During the breeding season, males are polygynous and often congregate in leks\u2014communal display areas\u2014where they sing and perform dramatic aerial maneuvers to attract females. These displays often involve rhythmic, U-shaped flight patterns designed to highlight their iridescent plumage and capture the attention of potential mates.\n\nThe female is solely responsible for all aspects of nesting and offspring care. She constructs a compact, cup-shaped nest from plant down and spider silk, camouflaging the exterior with lichen to blend into the forest foliage. Typically, she lays two eggs and provides all the incubation and feeding herself. This reproductive strategy allows the male to maximize his mating opportunities by defending multiple territories, while the female ensures the survival of the brood through meticulous nest concealment and dedicated parental investment.","diet":"The Crowned Woodnymph primarily subsists on nectar gathered from a diverse array of flowering plants, particularly favoring Heliconias, epiphytic bromeliads, and various species within the Rubiaceae and Ericaceae families. To fulfill its nutritional requirements for protein, this hummingbird also consumes small spiders and insects, which it captures by gleaning them from foliage or snatching them mid-flight through a method called hawking. A fascinating element of its dietary behavior is the distinction between the sexes: males often exhibit high levels of territoriality, aggressively defending productive floral patches, whereas females typically act as trapliners, visiting a consistent sequence of flowers over a wide area. Additionally, these birds are known to engage in nectar robbing by piercing the base of flowers with corollas too long for their bills, and they may even visit sap wells created by sapsuckers to supplement their energy intake.","colors":"The male Crowned Woodnymph features a brilliant violet-blue crown and belly contrasted by an iridescent emerald-green throat and upper back, while females are more subtly colored with metallic green upperparts and pale greyish underparts. Males possess a distinctive deeply forked, dark blue-black tail, whereas females have white-tipped outer tail feathers that provide camouflage against dappled forest light. Their intense iridescence shifts with the light, serving as both a mating signal for males and a way for females to blend into the tropical foliage.","fun_facts":"The Crowned Woodnymph is a fierce aerial gladiator, known for defending its floral territory with aggressive dives and high-speed chases against rivals and much larger birds alike. To construct its tiny, cup-shaped nest, it utilizes stretchy spider silk that allows the structure to physically expand as the chicks grow. On particularly cold nights, these birds can enter a state of torpor, a form of temporary hibernation where they drastically lower their body temperature and heart rate to conserve energy. While nectar is their primary food source, they are also expert \"hawkers,\" capable of performing acrobatic mid-air maneuvers to snatch small insects directly out of the sky for protein.","conservation_status_&_efforts":"Currently classified as a species of Least Concern on the IUCN Red List, the population trend of this hummingbird is considered to be decreasing due to ongoing habitat loss. The primary threats include deforestation and fragmentation of humid forests driven by agricultural expansion, logging, and infrastructure development. While the species shows some resilience by utilizing secondary growth and forest edges, the continued conversion of primary forest into monocultures significantly reduces its available nesting and foraging range.\n\nConservation efforts are largely centered on the protection of existing tropical forest ecosystems through the maintenance of national parks and private biological reserves across Central and South America. In regions like Costa Rica and Colombia, the species benefits from its presence in numerous protected areas that safeguard mid-elevation habitats. Additionally, broader reforestation initiatives and the establishment of biological corridors are being implemented to reconnect fragmented landscapes, ensuring genetic flow and providing stable resources for local populations.","endemic":false,"conservation_status":"Least Concern","ebird_link":{"url":"https:\/\/ebird.org\/species\/crowoo1","title":"View on Ebird","target":"_blank"},"animal_related_page":{"url":"https:\/\/animalia.bio\/crowned-woodnymph","title":"View on Animalia","target":"_blank"},"fauna_family":"Trochilidae","fauna_known_nicknames":"Violet-crowned Woodnymph, Blue-crowned Woodnymph","fauna_average_length":"9.5\u201311 cm \/ 3.7\u20134.3 in","fauna_average_weight":"3.5\u20135.5 g \/ 0.12\u20130.19 oz","fauna_wingspan":"10\u201312 cm \/ 4\u20134.7 in","fauna_key_physical_feature":"Iridescent violet crown and breast with a brilliant green throat in males","fauna_primary_diet":"Nectarivore (Nectar and small arthropods)","fauna_geographical_range":"Central America to Northern South America (Guatemala to Colombia and Venezuela)","fauna_preferred_habitat":"Humid lowland and montane forest understory, edges, and second-growth forests","fauna_social_structure":"Solitary and highly territorial","fauna_breeding_site":"Small cup nests built on low, horizontal branches or vines","fauna_conservation_status":"Least Concern (LC)","fauna_population_trend":"Decreasing","fauna_spanish_name":"Ninfa coronada","fauna_french_name":""},"_links":{"self":[{"href":"https:\/\/remote-expeditions.com\/fr\/wp-json\/wp\/v2\/fauna\/234364","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\/246706"}],"wp:attachment":[{"href":"https:\/\/remote-expeditions.com\/fr\/wp-json\/wp\/v2\/media?parent=234364"}],"wp:term":[{"taxonomy":"collection","embeddable":true,"href":"https:\/\/remote-expeditions.com\/fr\/wp-json\/wp\/v2\/collection?post=234364"},{"taxonomy":"country","embeddable":true,"href":"https:\/\/remote-expeditions.com\/fr\/wp-json\/wp\/v2\/country?post=234364"},{"taxonomy":"fauna-group","embeddable":true,"href":"https:\/\/remote-expeditions.com\/fr\/wp-json\/wp\/v2\/fauna-group?post=234364"},{"taxonomy":"fauna-type","embeddable":true,"href":"https:\/\/remote-expeditions.com\/fr\/wp-json\/wp\/v2\/fauna-type?post=234364"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
