Rouget's rail

Rouget's rail 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 Rouget's rail rather than just read about it. In short: Rouget's rail (Rougetius rougetii) is a species of bird in the family Rallidae. It is the only member of the genus Rougetius.

Key takeaways

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

Reference excerpt

Rouget's rail (Rougetius rougetii) is a species of bird in the family Rallidae. It is the only member of the genus Rougetius. It is found in Eritrea and Ethiopia.

Description Rouget's rail is about 30 cm (12 in) long. In coloration, it has olive brown back, and cinnamon-rufous underside. Sexes are alike. One female and male weighed 170 g (6.0 oz) and 220 g (7.8 oz), respectively.

Habitat and distribution It inhabits the Ethiopian and Eritrean highlands at 2,000–4,100 m (6,600–13,500 ft) where it frequents moorland, grassland, and marshy areas.

Behavior The diet of Rouget's rail consists of seeds, aquatic insects (namely water beetles), crustaceans, and small snails. It lays 4–5 eggs, which are incubated by the female and probably the male. Both parents raise the chicks, which remain with its parents until fully grown.

Worked examples

Example 1 — a first encounter with Rouget's rail

Start with the simplest possible case. Write down what Rouget's rail 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 Rouget's rail 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 Rouget's rail 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 Rouget's rail

In research: Rouget's rail 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 Rouget's rail 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: Rouget's rail is common in secondary-school and first-year university syllabi. It links to neighbouring topics Birds described in 1843, Birds of the Horn of Africa, Gruiformes stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Rouget's rail 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.
