Pigeon and Dove Taxonomy: Species Overview

Understanding Pigeon and Dove Taxonomy

Pigeons and doves represent a diverse and fascinating group of birds that belong to order Columbiformes and family Columbidae. Although these birds appear remarkably different in size, coloration, and behavior, they share important clinically significant anatomical and physiological characteristics that make them distinct from other avian species. Understanding their taxonomy is essential for veterinary professionals, bird enthusiasts, and those involved in pigeon care and management. This comprehensive overview explores the classification, characteristics, and diversity of pigeons and doves found in clinical practice and captive settings worldwide.

Order Columbiformes and Family Columbidae

Pigeons and doves belong to order Columbiformes, which is a large and diverse taxonomic group. Within this order, family Columbidae contains five subfamilies, 42 genera, and 308 distinct species. These birds are found on every continent except Antarctica, inhabiting virtually all types of terrestrial habitats ranging from tropical rainforests to arid deserts and urban environments. The remarkable adaptability of columbids to diverse environments has contributed to their widespread distribution and success as a bird family.

Columbids tend to be stocky birds with relatively small heads, short beaks, and a distinctive fleshy cere—a waxy covering at the base of the upper beak. They possess a characteristic bare ring of skin around their eyes and typically have short, squat legs with long keels. These physical characteristics, combined with their unique physiology, make pigeons and doves instantly recognizable among avian species.

Subfamilies Within Columbidae

Family Columbidae is organized into five distinct subfamilies, each containing different groups of pigeons and doves:

• Subfamily Columbinae: Contains true doves and pigeons, representing the largest and most diverse group
• Subfamily Didunculinae: Contains the tooth-billed pigeon, also known as the Manumea
• Subfamily Gourinae: Contains the crowned pigeons, known for their distinctive crested appearance
• Subfamily Otidiphabinae: Contains the pheasant pigeons, characterized by unique plumage and behavior

True Pigeons: Subfamily Columbinae

True pigeons belong to subfamily Columbinae, which consists of 21 genera and 46 species. This subfamily represents the core group of pigeons most commonly encountered in veterinary practice and human environments. Among the most significant species within this subfamily are members of genus Columba, which includes the rock dove and its various descendants.

Genus Columba: Rock Dove and Domestic Pigeons

The rock dove (Columba livia) holds paramount importance in understanding pigeon taxonomy and domestication. This species serves as the common ancestor of all domestic pigeons (Columba livia domestica). The domestication of rock doves occurred thousands of years ago, leading to the development of hundreds of distinct breeds and varieties. Domesticated pigeons that have returned to the wild are descended from the rock dove and are called city pigeons, street pigeons, or incorrectly referred to as feral pigeons. Street pigeons are found almost exclusively in urban areas near human populations, where they have adapted remarkably well to city environments.

Common Wood Pigeon

The common wood pigeon (Columba palumbus) is the most common pigeon species found in the United Kingdom and is abundant throughout southern and western Europe. This large bird displays primarily grey plumage with distinctive white markings on its neck and wings, along with pink-tinged feathers on its breast. The common wood pigeon migrates seasonally to northern and eastern parts of Europe and western Asia during winter months. This species is classified as Least Concern on the International Union for Conservation of Nature (IUCN) Red List, indicating stable and healthy population numbers.

Genus Streptopelia: Turtle Doves

The ringed turtle dove (Streptopelia risoria), also known as the Barbary dove, represents an important genus within true pigeons. This species originates from the savannahs and dry woodlands of Africa. The ringed turtle dove displays warm creamy buff coloration with a distinctive black semi-collar marking on the back of its neck, while the chin, belly, and tail coverts are tinged with white. The release of captive-bred specimens has led to the establishment of feral colonies in California, southern Florida, and parts of Illinois in the United States, demonstrating the adaptability of this species to new environments.

Genus Caloenas: Nicobar Pigeon

The Nicobar pigeon (Caloenas nicobarica) is a visually striking species native to the small islands of Malaysia and Polynesia. This beautiful bird features iridescent green feathers across its dorsum and wings, with distinctive long feathers that stream down its neck, creating a striking mane-like appearance. The Nicobar pigeon holds significant evolutionary importance as the closest living relative of the dodo (Raphus cucullatus), a large flightless bird that went extinct in the 1600s. The IUCN Red List status of the Nicobar pigeon is Near Threatened, indicating that conservation efforts are important for this species.

Domestic Pigeon Breeds and Varieties

Over millennia of selective breeding, humans have developed over 800 varieties of domesticated pigeons from the rock dove through intentional mutations and recombinations. These breeds are distinguished by multiple characteristics including size, beak and cere morphology, plumage coloration and design, feather structure and morphology, and breed-specific behaviors. Nine major groups of domesticated pigeons have been distinguished in the pigeon fancy, each with unique characteristics and purposes.

Asian Feather and Voice Pigeons

Specialized breeds including the fantail, trumpeter, and Jacobin possess extensive feathering and distinctive laughing or trumpeting vocalizations. Fantail pigeons are particularly notable for their rounded bodies and large, flat tails that resemble tiny peacocks. These docile birds represent a very popular and very old breed that appeals to pigeon enthusiasts worldwide.

Color Pigeons

Many different varieties of pigeons have been bred specifically for their aesthetic beauty and distinctive coloring or markings. These varieties may display pastel colors including soft blues, grays, striking black and white combinations, and many different patterns. Notable color pigeon breeds include the swallow, Medena, Danish Suabian, and archangel. Archangels are black pigeons with a distinctive coppery sheen, while Medenas are stocky, gaily marked pigeons with short tails.

Pouters and Croppers

Pouters and croppers, such as the English pouter, Norwich cropper, and pygmy pouter, possess distinctive long, pencil-like legs and the remarkable ability to inflate the crop with air, making this region appear like a balloon. Some pouters are crested, while others have feathered feet and legs, adding to their distinctive appearance.

Frills and Owls

Breeds like the old German owl, Oriental frill, and Aachen Lacquer shelled owl possess stunted beaks and extraordinary chest feathers that distinguish them from other pigeon varieties. These breeds are prized by pigeon fanciers for their unusual and striking physical characteristics.

Clinical Significance of Pigeon Diversity

Although pigeons and doves are a highly diverse group of birds, they share important clinically significant anatomical and physiological characteristics that are relevant to veterinary practice. Understanding the taxonomy and diversity of pigeons is essential for veterinary professionals who encounter these birds in clinical practice. The clinical approach to columbiform care relies on the same fundamental concepts of “One Medicine” used in all species, yet many infectious diseases of pigeons are relatively unique to this taxonomic group or are much more prevalent in pigeons when compared to psittacine birds or songbirds.

Common Species in Clinical Practice

While many possible species, breeds, and varieties may be seen in veterinary clinical practice, some of the most common specimens are members of genus Columba. These include racing pigeons, kept for their competitive abilities in homing and racing competitions; fancy pigeons, maintained by pigeon enthusiasts for their aesthetic qualities and breed characteristics; and street pigeons, which represent the feral descendants of domestic rock doves living in urban environments.

Geographic Distribution and Habitat

Pigeons and doves demonstrate remarkable geographic distribution across diverse habitats worldwide. From urban environments to agricultural areas, forests, grasslands, and deserts, columbids have successfully adapted to virtually every terrestrial habitat except the most extreme polar regions. This adaptability has made pigeons one of the most successful bird families globally, with populations thriving in close association with human settlements and agricultural practices.

Conservation Status of Pigeon Species

The conservation status of pigeon species varies considerably. While many species such as the common wood pigeon maintain healthy populations classified as Least Concern, others such as the Nicobar pigeon are classified as Near Threatened, requiring conservation attention. Historical extinctions, including that of the passenger pigeon (Ectopistes migratorius), serve as important reminders of the impacts that human activities can have on pigeon populations.

Frequently Asked Questions (FAQs)

Q: What is the difference between pigeons and doves?
