Common Gallinule
Gallinula galeata · also called american moorhen
Clucking and whinnying from deep within dense marsh vegetation, a common gallinule looks so similar to its Old World counterpart that only careful genetic study in 2011 finally confirmed the two belonged to entirely separate species.
Overview
The common gallinule, Gallinula galeata, is a widespread waterbird native to wetland habitat across much of North, Central, and South America. Its close resemblance to the Old World common moorhen, only recently confirmed as a distinct species in 2011, distinctive red-and-yellow bill shield, and long toes adapted for walking across floating vegetation make it one of the more taxonomically interesting waterbirds found throughout the Americas.
Nearly a mirror image
For decades, researchers treated this species and its Old World counterpart as one and the same, and it took careful genetic and physical comparison to finally reveal that two populations separated by an ocean had quietly diverged into distinct species all along.
Status
Least Concern, remaining widespread across suitable wetland habitat throughout North, Central, and South America.
Common Gallinule: common questions
What is the difference between the common gallinule and the common moorhen?
These two species were considered a single species until a 2011 taxonomic revision split them apart based on genetic and physical differences, with the common gallinule occupying the Americas and the common moorhen instead found across Europe, Africa, and Asia, despite the two looking nearly identical.
How does the common gallinule walk on floating plants?
This species has notably long, unwebbed toes that distribute its weight effectively across a wide surface area, allowing it to walk confidently across floating vegetation such as lily pads without sinking.
What sounds does the common gallinule make?
This species produces a varied range of calls, including clucks, squawks, and whinnying notes, often used to communicate within dense marsh vegetation where visibility between individuals is limited.
Where does the common gallinule live?
This species is native to wetland habitat across a broad range spanning much of North, Central, and South America, occupying a wide variety of freshwater marshes and ponds within that range.
