5-3-2020 KANHA NAT PARK, INDIA - COMMON KINGFISHER (FEMALE) (Alcedo atthis)

The common kingfisher (Alcedo atthis) is a small, brilliantly colored bird (16–17 cm) with electric blue upperparts and orange underparts, known for hunting fish along slow-flowing, clear rivers, streams, and canals. They are highly territorial, dive at high speed to catch fish, and require roughly 60% of their body weight in food daily. 

Key Facts About Common Kingfishers

Hunting & Diet: They hunt by diving into water to catch small fish (minnows, sticklebacks) and invertebrates, using their long, sharp, black, and orange bills. They often beat their prey against a perch to consume it headfirst.

Physical Features: They have a short tail, large head, and long, dagger-like bill. Males have completely black bills, while females possess an orange-red underbill.

Habitat & Range: Common in Europe, Asia, and North Africa, these birds prefer water sources, but in winter, they may move to the coast to avoid freezing inland waters.

Nesting: They dig tunnels in vertical riverbanks to create nests, producing 2–3 broods per year, each consisting of 6–7 eggs.

Flight: They are frequently seen in direct, low, and fast flight, appearing as a bright blue streak over the water.

Behavior: They are highly territorial, and they may fall victim to predators like cats, foxes, and mink.

Lifespan: They live on average seven years, though they can reach up to 15 years.

Engineering Inspiration: The design of the Japanese bullet train was inspired by the kingfisher's beak, which allows for efficient, low-impact, high-speed movement. 

The Common Kingfisher (Alcedo atthis), also known as the Eurasian Kingfisher or River Kingfisher, is a vibrant, pocket-sized gem among birds. With its unmistakable silhouette characterized by a stout body, large head, and a long, sharp bill, it is a sight to behold. The male boasts a striking palette with blue upperparts, an orange belly, and a conspicuous white throat and collar. The female mirrors the male's vivid colors but can be discerned by her orange-red lower mandible with a black tip.

To identify the Common Kingfisher, look for its bright blue and orange plumage and its rapid, low flight over water. The male's bill is predominantly black with some red at the base, while the female's bill features an orange-red lower mandible. Juveniles resemble adults but have duller, greener upperparts and paler underparts. Their black bill and legs gradually acquire the adult coloration.

The Common Kingfisher is found along clear, slow-flowing streams and rivers, as well as lakes with well-vegetated banks. It prefers areas with overhanging branches that provide vantage points for hunting. In winter, it may move to coastal regions, frequenting estuaries, harbors, and rocky shores.
