São Tomé kingfisher

São Tomé 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 São Tomé kingfisher rather than just read about it. In short: The São Tomé kingfisher (Corythornis cristatus thomensis) is a bird in the family Alcedinidae. It is endemic to São Tomé, an island off the west coast of Africa in the Gulf of Guinea and was first described by the Italian ornithologist Tommaso Salvadori in 1902 under the binomial name Corythornis thomensis.

Key takeaways

São Tomé 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 São Tomé kingfisher to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of São Tomé kingfisher from memory before moving on to harder problems.

Reference excerpt

The São Tomé kingfisher (Corythornis cristatus thomensis) is a bird in the family Alcedinidae. It is endemic to São Tomé, an island off the west coast of Africa in the Gulf of Guinea and was first described by the Italian ornithologist Tommaso Salvadori in 1902 under the binomial name Corythornis thomensis. A molecular phylogenetic study published in 2008 showed that the São Tomé kingfisher is a subspecies of the malachite kingfisher. Its habitat includes forest, inland wetlands, marine intertidal areas, marine coastal areas, and urban areas.

Worked examples

Example 1 — a first encounter with São Tomé kingfisher

Start with the simplest possible case. Write down what São Tomé 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 São Tomé 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 São Tomé 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 São Tomé kingfisher

In research: São Tomé 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 São Tomé 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: São Tomé kingfisher is common in secondary-school and first-year university syllabi. It links to neighbouring topics Birds described in 1902, Coraciiformes stubs, Corythornis, so understanding it makes those chapters shorter.
In everyday life: Look for São Tomé 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.
