White-collared Manakin

The white-collared manakin is a passerine bird in the manakin family. It is a resident breeder in the tropical New World from southeastern Mexico to Costa Rica and the extreme west of Panama. It typically inhabits thickets at the edges of moist forest, tall secondary growth and old cacao plantations. It is a small, plump bird about 11 centimetres (4.3 in) long. Males have a black crown, mid-back band, wings and tail, an olive-green rump and yellow belly. Females and juveniles are olive-green with yellow bellies and resemble female orange-collared manakins. At breeding time, males are involved in lekking behaviour on the forest floor during which they puff out their neck feathers. This is a fairly common species with a wide range, and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".

White-collared Manakins are best known for their intricate lekking behavior, where males gather in small groups (leks) on the forest floor to perform competitive displays for visiting females. Each male clears a small display court, meticulously removing leaf litter to create a bare patch, and uses low perches for acrobatic jumps, rapid flights, and wing-snapping maneuvers. The wing snaps are produced by modified secondary feathers and are audible from considerable distances. Males are highly territorial within the lek, defending their courts from rivals. Outside of the breeding season, the species is generally solitary and secretive. Foraging occurs primarily in the understory, where individuals pluck small fruits, especially from Melastomataceae, Rubiaceae, and Lauraceae, often hovering briefly to snatch food. Insects and spiders are taken opportunistically, especially during periods of high protein demand such as chick-rearing. Daily activity peaks at dawn and late afternoon, with midday spent resting in dense cover. Vocalizations are relatively simple, consisting of short, sharp 'tic' or 'pip' notes, but mechanical wing sounds are the primary acoustic signals.

Breeding in White-collared Manakins is highly seasonal, typically coinciding with the onset of the rainy season (March to July in Costa Rica). Males perform at leks to attract females, with the most dominant and skilled performers securing the majority of matings. After mating, females are solely responsible for nest construction, incubation, and chick rearing. The nest is a small, shallow cup woven from plant fibers, placed 1–3 meters above ground in dense vegetation. Clutch size is usually two eggs, which are pale with brownish markings. Incubation lasts about 17–20 days, and the altricial chicks fledge approximately 13–15 days after hatching. Females feed the chicks primarily with soft fruits and supplement with insects for protein. There is no male parental involvement after copulation.

The species exhibits several remarkable adaptations for its lekking lifestyle. Males have evolved specialized secondary wing feathers that are thickened and stiffened, enabling the production of loud mechanical snaps and buzzes during display. Their strong legs and feet facilitate rapid, agile movements and repeated leaping between perches. The cryptic coloration of females and juveniles provides effective camouflage against predators in the dense understory. Their diet is adapted to exploit a wide variety of small, soft fruits, and their digestive system efficiently processes fruit pulp while excreting seeds, aiding in forest regeneration. The ability to clear and maintain display courts is a behavioral adaptation linked to sexual selection.

While the White-collared Manakin does not have a prominent role in indigenous folklore or local mythology, its striking appearance and unique courtship displays have made it a subject of interest for birdwatchers and ecotourism in Central America. The species is sometimes featured in educational materials and field guides as an example of lekking behavior and sexual selection. Its presence is considered an indicator of healthy understory habitats.

Recent research on Manacus candei has focused on the biomechanics of wing-sound production, sexual selection, and the genetic basis of plumage and display traits. Studies using high-speed videography and acoustic analysis have elucidated how specialized wing feathers generate mechanical sounds. Genetic analyses have explored hybridization zones between White-collared and Golden-collared Manakins (Manacus vitellinus) in Panama, revealing insights into reproductive isolation and speciation. Long-term monitoring of lek dynamics has provided data on male site fidelity, display success, and the influence of habitat quality on reproductive output. Ongoing studies are investigating the impact of habitat fragmentation on lek stability and gene flow.

The White-collared Manakin is currently classified as Least Concern on the IUCN Red List.

Currently, the White-collared Manakin is classified as Least Concern by the IUCN due to its wide distribution and stable population trends. However, localized threats include habitat loss and fragmentation from agricultural expansion, logging, and conversion of forests to pasture or monoculture plantations. Despite this, the species shows some resilience by utilizing secondary growth and shaded plantations (e.g., cacao) as alternative habitats. Climate change poses a potential long-term threat through alteration of forest structure and fruiting phenology. The species is not targeted by hunting or the pet trade. Ongoing deforestation in Central America could pose future risks if not mitigated.
