White-bellied kingfisher

White-bellied kingfisher is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand White-bellied kingfisher rather than just read about it. In short: The white-bellied kingfisher (Corythornis leucogaster) is a species of kingfisher in the subfamily Alcedininae that occurs in Mali and throughout the African tropical rainforest. The first formal description of the species was by the British zoologist Louis Fraser in 1843 under the binomial name Halcyon leucogaster.

Key takeaways

White-bellied kingfisher belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect White-bellied kingfisher to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of White-bellied kingfisher from memory before moving on to harder problems.

Reference excerpt

The white-bellied kingfisher (Corythornis leucogaster) is a species of kingfisher in the subfamily Alcedininae that occurs in Mali and throughout the African tropical rainforest. The first formal description of the species was by the British zoologist Louis Fraser in 1843 under the binomial name Halcyon leucogaster. There are three subspecies:

Corythornis leucogaster bowdleri (Neumann, 1908) – far north-eastern Guinea, Mali and Upper Guinean forests Corythornis leucogaster leucogaster (Fraser, 1843) – Nigeria to north west Angola, Bioko Island Corythornis leucogaster leopoldi (Dubois, AJC, 1905) – east Congo to south Uganda and northwest Zambia The white-bellied kingfisher is 13 cm (5.1 in) in length with a weight of around 14.5 g (0.51 oz). It has ultramarine upperparts and a red bill. The underparts are rufous-chestnut apart from a central white band. The sexes are alike.

Worked examples

Example 1 — a first encounter with White-bellied kingfisher

Start with the simplest possible case. Write down what White-bellied kingfisher claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to White-bellied kingfisher before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about White-bellied kingfisher ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of White-bellied kingfisher

In research: White-bellied kingfisher appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses White-bellied kingfisher in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: White-bellied kingfisher is common in secondary-school and first-year university syllabi. It links to neighbouring topics Birds described in 1843, Birds of the African tropical rainforest, Birds of the Gulf of Guinea, so understanding it makes those chapters shorter.
In everyday life: Look for White-bellied kingfisher outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
