Western Lewin's rail

Western Lewin'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 Western Lewin's rail rather than just read about it. In short: The western Lewin's rail (Lewinia pectoralis clelandi), also known as Cleland's rail, Lewin's rail (western) or the Lewin water rail, is an extinct and little known subspecies of Lewin's rail that was endemic to Western Australia. There are only four specimens, one in the Australian Museum and three in the British Museum.

Key takeaways

  • Western Lewin'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 Western Lewin's rail to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Western Lewin's rail from memory before moving on to harder problems.

Reference excerpt

The western Lewin's rail (Lewinia pectoralis clelandi), also known as Cleland's rail, Lewin's rail (western) or the Lewin water rail, is an extinct and little known subspecies of Lewin's rail that was endemic to Western Australia. There are only four specimens, one in the Australian Museum and three in the British Museum. The subspecific name honours Australian ornithologist John Burton Cleland.

Description The rail had a rufous to chestnut crown and neck with heavy black streaking, grey cheeks, throat and breast, with the rest of the upper body streaked black and brown. The wings were dark brown with narrow white barring, while the belly, flanks and undertail were black, barred white or buff. The bill was long and slender, pink with a darker tip; the eyes brown to red, and the legs and feet pinkish grey. The length of the rail was 21–28 centimetres (8.3–11.0 in), with a bill length of 42 mm (1.7 in).

Distribution and habitat The rail had a restricted distribution in the far south-west of Western Australia, from Margaret River to Albany, and inland as far as Bridgetown. Its core habitat was the dense vegetation fringing, or emerging from, saline, brackish and freshwater wetlands, though it could also sometimes be found in grassland or in thick coastal scrub.

Conservation status Always scarce, the subspecies became extinct because of the destruction and modification of its wetland habitats, mainly through drainage and clearance burning for agriculture and settlement. There have been no reports of its existence since 1932.

Worked examples

Example 1 — a first encounter with Western Lewin's rail

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

In research
Western Lewin'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 Western Lewin'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
Western Lewin's rail is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bird extinctions since 1500, Birds described in 1911, Birds of Western Australia, so understanding it makes those chapters shorter.
In everyday life
Look for Western Lewin'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.
