Nicobar Pigeon

The Nicobar Pigeon is one of the most visually distinctive pigeons in the world, sporting elongated, pointed neck feathers that resemble a mane and shimmer with iridescent color as it moves. It is closely tied to small offshore islands, where it roosts and breeds in large numbers, flying daily to nearby larger islands to feed.

The neck and upper mantle feathers are greatly elongated, narrow, and pointed, forming a distinctive hackle that ripples with metallic green, copper, and bronze iridescence depending on the angle of light. The body plumage is otherwise dark slate-grey with a coppery sheen. The short, square tail is pure white, contrasting sharply with the dark body and unique among pigeons of similar size. No other pigeon combines elongated iridescent neck hackles with an all-white tail.

Sexes are similar, though males typically show slightly longer and more developed neck hackles and richer iridescence than females. Juveniles lack the elongated neck feathers, appearing shorter-necked and duller with a dark tail that whitens with maturity. Adults undergo a gradual molt of the hackle feathers, which regrow to their full length between breeding cycles.

Restricted to small, often uninhabited islands and coastal forest fringes from the Nicobar Islands and surrounding archipelagos east through Southeast Asia to the Solomon Islands and Palau. Birds commute daily between breeding islets and larger foraging islands, and populations are largely sedentary within their island range.

Nicobar Pigeons feed on fallen seeds, fruit, and other forest floor items, foraging in small to large flocks on the ground. They nest colonially, building stick platform nests in low trees on predator-free islets. Their voice includes a deep, resonant guttural call. Their strong dependence on small islands makes them vulnerable to habitat disturbance, though conservation status is best checked with current regional assessments.
