Key Differences Between Purple Swamphen and Purple Gallinule

Here are the key differences between the purple swamphen and purple gallinule:

Size Comparison

  • Purple Swamphen: The Purple Swamphen boasts a notably larger size, commanding attention in wetland environments. Its robust physique and relatively larger frame contribute to its prominent presence among other waterfowl species.
  • Purple Gallinule: Conversely, the Purple Gallinule exhibits a smaller size, showcasing a compact and diminutive stature. This disparity in size serves as a distinguishing factor from the larger and more imposing Purple Swamphen.

Plumage Color

  • Purple Swamphen: The Purple Swamphen’s name itself reflects its predominant plumage color.
    Cloaked in shades ranging from deep blue to regal purple, this bird’s feathers create a striking impression. This rich and vibrant plumage sets it apart as it elegantly maneuvers through dense wetland vegetation.
  • Purple Gallinule: In contrast, the Purple Gallinule showcases a unique blend of colors. Its plumage displays a mesmerizing array of bluish-purple tones, with a vivid greenback that catches the eye.
    This coloration provides effective camouflage within its marshy habitats and adds a touch of iridescence to its presence.

Frontal Shield

  • Purple Swamphen: The frontal shield of the Purple Swamphen is a noteworthy feature. Colored in a vivid shade of red, this shield adorns its forehead and contributes to its distinctive appearance.
    The bright red shield serves as a symbol of its territorial nature, as well as a striking contrast to its otherwise rich plumage.
  • Purple Gallinule: Conversely, the Purple Gallinule boasts a frontal shield that departs from the solid red hue.
    Its shield presents a delicate bluish-white shade, a subtle yet elegant adornment to its facial features. This unique coloration complements its overall plumage and is one of the key characteristics that differentiate it from the Swamphen.

Bill Color

  • Purple Swamphen: The bill of the Purple Swamphen complements its striking appearance. Colored in a bold red hue, the bill serves both functional and aesthetic purposes.
    Its bright coloration aligns with its frontal shield and creates a visual harmony that contributes to its overall appeal.
  • Purple Gallinule: The Purple Gallinule’s bill features an intriguing color combination. The bill is predominantly red, much like that of the Swamphen, but it sports a distinctive yellow tip.
    This subtle touch of yellow adds a dash of vibrancy to its facial features, accentuating its uniqueness within the avian realm.

Bill Thickness

  • Purple Swamphen: The bill of the Purple Swamphen is characterized by its relatively thicker structure. This thickness is an adaptation that aligns with its omnivorous diet and foraging behavior.
    The robust bill enables it to efficiently grasp and manipulate various types of food items, from aquatic plants to small vertebrates.
  • Purple Gallinule: Conversely, the bill of the Purple Gallinule does not exhibit the same degree of thickness as that of the Swamphen.
    While still functional for its dietary needs, the Gallinule’s bill presents a more refined and slender form. This difference in bill structure reflects the species’ distinct feeding strategies and preferences.

Leg Color

  • Purple Swamphen: Leg color is one of the pronounced differentiators between these two birds. The Purple Swamphen’s legs take on a standard coloration, often matching its plumage hues. These legs serve as sturdy pillars, enabling the Swamphen to navigate its marshy environment with ease.
  • Purple Gallinule: In contrast, the Purple Gallinule sports a vivid yellow leg color.

  • Purple Gallinule: On the other hand, the Purple Gallinule exhibits shorter legs relative to its body size. These legs are specialized for a unique adaptation – the ability to walk on floating vegetation. Its legs’ length and toe structure allow it to nimbly navigate across water lilies and other aquatic plants.


  • Purple Swamphen: Habitat preference is a defining characteristic of these two birds. The Purple Swamphen finds solace in a variety of wetland habitats, from swamps to marshes. Its larger size and sturdy legs equip it to thrive in areas with dense vegetation and open waters.
  • Purple Gallinule: The Purple Gallinule, while also a wetland enthusiast, leans more toward freshwater marshes and ponds. These habitats align with its smaller size, enabling it to navigate the intricate networks of floating vegetation, where it often forages and nests.

Floating Abilities

  • Purple Swamphen: Floating abilities are not a hallmark of the Purple Swamphen. Its sturdy legs, while facilitating movement through water, are not optimized for treading on the surface of water bodies. Instead, it excels in wading through wetland vegetation.
  • Purple Gallinule: The Purple Gallinule, in contrast, possesses an extraordinary talent for walking on floating vegetation. Its long toes and relatively light body allow it to step delicately across water lilies and other aquatic plants, affording it a unique advantage in its foraging strategy.


  • Purple Swamphen: Dietary habits diverge between these species. The Purple Swamphen is an omnivore, consuming a wide variety of foods. Its diet ranges from aquatic plants and insects to small vertebrates. Its sturdy bill and thicker build cater to its diverse culinary preferences.
  • Purple Gallinule: The Purple Gallinule, too, maintains an omnivorous diet, but with a slightly different focus.
    It feeds on plant material and small animals, displaying a preference for the vegetation-rich environments it inhabits. Its slender bill is adept at plucking plant matter and capturing delicate aquatic creatures.

Foraging Behavior

  • Purple Swamphen: Foraging behavior sets these species apart. The Purple Swamphen, a versatile omnivore, is skilled in harvesting sustenance from its habitat.
    It adeptly seeks out insects, small vertebrates, aquatic invertebrates, and a variety of plant matter. Its robust bill and long legs enable it to efficiently navigate dense vegetation while capturing a diverse range of prey.
  • Purple Gallinule: Similarly, the Purple Gallinule employs an omnivorous diet, but its foraging strategy leans towards plant material and small animals. Its preference for aquatic plants, along with its slender bill, complements its ability to pluck vegetation and capture delicate aquatic organisms.

Native Range

  • Purple Swamphen: The native range of the Purple Swamphen spans across diverse regions. This bird is found in parts of Africa, southern Europe, and southern Asia. Its presence in these areas is integral to the wetland ecosystems it inhabits.
