Golden-collared Manakin

Fascinating facts about the Golden-collared Manakin

• At just 10-12 cm long and 15-24 g in weight, the golden-collared manakin fits in the palm of your hand, yet the males sport a jet-black crown and a glossy golden-yellow “collar” that rivals a tiny sunrise. That flash of colour shows how sexual selection can drive bold plumage even in the tiniest birds.
• Four distinct subspecies stretch from Panama’s Caribbean coast to Colombia’s Western Andes, each tweaking the yellow hue of the male’s collar or the darkness of the green belly. These subtle regional palettes illustrate how isolated habitats can carve fine variations into a single species.
• Males perform a two-part “chee-poo” courtship call, and scientists discovered that blocking peripheral androgen receptors lengthens the “chee” and lowers the “poo” pitch. This reveals that hormones outside the brain directly shape the soundtrack of love in birds.
• Females alone build a shallow cup nest 0.5-2 m above ground, weaving bark, grass, rootlets and a silk lining of spider web. Raising just two eggs, they shoulder all incubation and feeding duties, a reminder that even in species with flashy male displays, the survival story rests on the silent work of females.
• Despite a decreasing trend, the species still boasts at least 500,000 mature individuals across a range that climbs to 1,200 m elevation. Its abundance in both protected areas and forest edges shows how adaptable manakins can thrive when even small patches of forest are left intact.

About the Golden-collared Manakin

The golden-collared manakin (Manacus vitellinus) is a diminutive, flamboyant bird that flits through the lowland and foothill forests of Panama and Colombia. Measuring just 10 to 12 cm in length and weighing 15 to 24 g, the male of the nominate subspecies dons a jet-black crown, back, wings and tail, while a glossy golden-yellow collar sweeps from chin to nape, framing an olive-green breast washed with yellow-olive. Females are a subtler olive, their plumage muted but highlighted by a paler yellow-olive belly and dusky wings edged in olive. Across its four subspecies, vitellinus, amitinus, milleri, and viridiventris, variations in collar hue and belly coloration add a mosaic of shades to the species’ appearance, while all retain a mouse-brown iris, black bill, and legs ranging from bright orange to dull scarlet. In the humid understory, this manakin feeds primarily on a buffet of tiny fruits, snatching them from perches or short sallies, and supplements its diet with occasional insects. It prefers forest edges, watercourses, and regenerating clearings, shunning the deep interior. Males perform acrobatic lek displays, punctuated by a distinctive "chee-poo" call whose timing is fine-tuned by peripheral androgen receptors, a rare glimpse into how hormones shape avian courtship. Females alone build shallow, spider-web-bound cups 0.5–2 m above ground, lay two cream-colored eggs, and raise the chicks without male assistance, embodying the solitary dedication of many tropical passerines.
