Physical Features:

  • Male: Adult males of the western European subspecies exhibit striking green-blue upperparts with a pale azure-blue back and rump. They have a distinctive rufous patch near the base of the bill and a matching ear-patch. The neck is adorned with a green-blue stripe, complemented by a white blaze and throat. Underparts are rufous, and the bill is black with crimson at the base. Bright red legs and feet complete the vibrant appearance.
  • Female: Females resemble males but can be distinguished by their orange-red lower mandible with a black tip.
  • Juvenile: Juveniles have duller and greener upperparts and paler underparts compared to adults. Their bills and legs are initially black.

Physical Dimensions:

  • The common kingfisher typically measures around 16 centimeters (6.3 inches) in length, with a wingspan of approximately 25 centimeters (9.8 inches).
  • They weigh between 34–46 grams (1.2–1.6 ounces).

Molt Cycle:

  • Feathers are molted gradually between July and November, with primary flight feathers taking 90–100 days to molt and regrow. Individuals that molt late may suspend their molt during cold winter weather.

Flight Pattern:

  • The flight of the common kingfisher is characterized by its speed, directness, and low trajectory over the water. Short, rounded wings enable rapid movement, creating an electric-blue “flash” down its back as it flies.

Geographic Distribution:

  • Found across North Africa, Europe, and Asia north of the Himalayas, the common kingfisher is the only small blue kingfisher in these regions. In South and Southeast Asia, it may be confused with similar species, but distinctive rufous ear patches help differentiate it.

Vocalizations:

  • While the common kingfisher does not have a distinct song, its flight call is a short, sharp whistle, often repeated two or three times. Anxious individuals emit a harsh “shrit-it-it,” while nestlings call for food with a churring noise.

Feeding Behavior of the Common Kingfisher

Hunting Technique: The common kingfisher employs a classic hunting strategy, perching 1–2 meters above the water on a branch, post, or riverbank. With its bill pointed downwards, it scans the water for prey, bobbing its head to gauge distance before making a steep plunge to seize its target, typically no deeper than 25 centimeters below the surface.

Prey Capture and Handling: Upon spotting prey, the kingfisher opens its wings underwater to facilitate movement and protect its open eyes with the clear third eyelid. After seizing its catch, it returns to its perch, where the fish is adjusted and crushed against the perch several times until subdued. Once dead, the fish is positioned lengthways and swallowed head-first. Periodically, the bird regurgitates small grayish pellets containing indigestible remains.

Diet Composition: Fish comprise the primary diet of the common kingfisher, with prey sizes ranging up to 12.5 centimeters, although the average size consumed is around 2.3 centimeters. Typical prey species include minnows, sticklebacks, small roaches, and trout, with fish making up approximately 60% of meal items. In addition to fish, the kingfisher also feeds on aquatic insects like dragonfly larvae and water beetles, as well as crustaceans such as freshwater shrimps, particularly in winter.

Feeding Dynamics: Studies have shown that food provisioning rates increase with brood size, with chicks consuming substantial amounts of fish during the fledging period. Each chick may consume an average of 334 grams of fish, representing a significant portion of their body mass. The common kingfisher’s daily energy consumption during this period is estimated at 73.5 kJ per chick.

Visual Adaptations for Underwater Hunting: To overcome the challenges of underwater hunting, the common kingfisher possesses specialized visual adaptations. These include dual foveae in the eyes, enabling the bird to switch between central and auxiliary foveae to maintain visual acuity underwater.

Breeding Behavior of the Common Kingfisher

Territoriality and Solitary Habits: The common kingfisher, like its kin, is fiercely territorial, needing control over a suitable stretch of river to sustain its voracious appetite, requiring up to 60% of its body weight in daily meals. Solitary for much of the year, it typically roosts alone in dense cover.

Territorial Defense and Courtship: When another kingfisher encroaches upon its territory, confrontations ensue, often leading to aggressive displays and occasional fights. Pairs begin to form in autumn, but each bird maintains a separate territory, with territories spanning up to 3.5 kilometers. Courtship involves the male chasing the female while calling, followed by ritual feeding, culminating in copulation.

Nesting Habits: The nest is situated in a burrow excavated by both members of the pair, usually in a low vertical riverbank or occasionally in a quarry. The burrow, typically 60–90 centimeters long, leads to an enlarged chamber. Though unlined, the nest cavity accumulates a litter of fish remains and solid pellets.

Egg Laying and Incubation: Common kingfishers typically lay two to ten glossy white eggs, each around 1.9 centimeters in breadth and 2.2 centimeters in length, weighing approximately 4.3 grams. Incubation, performed by both sexes during the day but solely by the female at night, lasts 19–20 days. The incubating bird sits trance-like, facing the tunnel, and may cast pellets.

Young Development and Feeding: After hatching, the altricial young remain in the nest for an additional 24–25 days, sometimes longer. Once sufficiently large, they venture to the burrow entrance to be fed. Common kingfishers may rear two or occasionally three broods in a single breeding season, displaying remarkable parental dedication and adaptability.

Adaptations of the Common Kingfisher

Early Life Challenges: Fledged juveniles face significant hazards in their early days, particularly during their initial dives into the water. Approximately four days after leaving the nest, inexperienced fledglings may become waterlogged and risk drowning. Furthermore, many young kingfishers fail to master fishing skills before being expelled from their parents’ territory, with only about half surviving beyond a week or two.

Survival Strategies: The majority of kingfishers succumb to cold weather or food scarcity, with severe winters posing a significant threat to the population. Summer floods can also wreak havoc, destroying nests and hampering fishing efforts, leading to starvation among the brood. Despite these challenges, approximately one-quarter of young individuals manage to survive to breed the following year, a sufficient number to sustain the population.

Adult Mortality: Similarly, only one-quarter of adult kingfishers survive from one breeding season to the next. Few individuals live longer than one breeding season, although records show that the oldest known bird reached 21 years of age. Various factors contribute to adult mortality, including predation by cats and rats, collisions with vehicles and windows, and human disturbance of nesting birds, such as riverbank construction activities involving heavy machinery.

Mating Behavior of the Common Kingfisher

Monogamous Pairing: Common kingfishers exhibit serial monogamy, seeking a new mate each year. They nest individually, with each pair establishing their own nesting site along sandy banks beside streams.

Courtship and Copulation: Before copulation, the male commonly presents the female with food, typically a fish. This offering serves as a form of courtship behavior. Copulation follows this ritual, with mating pairs engaging in reproductive activities to initiate egg fertilization.

Breeding Cycle: Common kingfishers may lay 2-3 clutches of eggs annually, with the first typically in April and another in July, sometimes followed by a third in early October. Nest sites vary, often located in holes in walls, rotten tree stumps, or termite mounds, where the birds excavate tunnels to create nest chambers.

Nest Construction and Incubation: Both male and female common kingfishers collaborate in excavating burrows, typically 50 to 90 centimeters long. After completing the nest chamber, the female lays 6 to 7 white eggs, which both parents incubate for approximately 19 to 21 days. Incubation duties are shared, with the female primarily brooding at night and both parents taking turns during the day.

Parental Care and Fledging: Once hatched, the young kingfishers receive food from both parents. They fledge at around 23-24 days of age, sometimes later. After about four days, they make their first dive into the water. As they quickly become independent, they depart from the territory where they were born, continuing the cycle of life for common kingfishers.
