Glossy Ibis
Plegadis falcinellus · also called glossy ibises
At first glance across a marsh, a glossy ibis looks almost entirely plain and dark, until the sun catches its feathers at just the right angle and a hidden sheen of bronze, purple, and green suddenly reveals itself.
Overview
The glossy ibis, Plegadis falcinellus, is a widely distributed wading bird native to wetland and coastal habitat across the Americas, Europe, Africa, Asia, and Australia. Its subtle iridescent plumage and status as one of the most globally widespread ibis species make it one of the more understated yet far-ranging wading birds found anywhere.
Colour that hides in plain sight
Most people walk past a glossy ibis assuming it’s simply a dark, unremarkable wading bird, entirely unaware that a shift in the light would reveal a genuinely iridescent display most other dark-plumaged birds simply don’t carry.
Status
Least Concern, increasing — widespread across its broad global range and expanding in parts of North America in recent decades.
Glossy Ibis: common questions
Is the glossy ibis actually colourful?
Yes, though it can be easy to miss — a breeding adult glossy ibis displays an iridescent sheen of bronze, purple, and green across its otherwise dark plumage, a colourful detail that only becomes obvious in good light up close, since from a distance the bird can look almost entirely plain brown or black.
How widespread is the glossy ibis?
The glossy ibis has one of the broadest global distributions of any ibis species, found across parts of every inhabited continent except Antarctica, a range far more extensive than most of its ibis relatives, many of which are restricted to a single region.
Does the glossy ibis nest alone?
No, the glossy ibis typically nests in mixed colonies alongside herons, egrets, and other ibis species, often building nests in trees or shrubs positioned over water for added protection from ground predators.
Where does the glossy ibis live?
The glossy ibis is native to wetland and coastal habitat across parts of the Americas, Europe, Africa, Asia, and Australia, and has expanded its breeding range northward and westward across parts of North America in recent decades.
