Red-billed spurfowl

Red-billed spurfowl 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 Red-billed spurfowl rather than just read about it. In short: The red-billed spurfowl (Pternistis adspersus), also known as the red-billed francolin, is a species of bird in the family Phasianidae. It is found in Southern Africa, including Angola, Botswana, Namibia, South Africa, Zambia, and Zimbabwe.

Key takeaways

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

Reference excerpt

The red-billed spurfowl (Pternistis adspersus), also known as the red-billed francolin, is a species of bird in the family Phasianidae. It is found in Southern Africa, including Angola, Botswana, Namibia, South Africa, Zambia, and Zimbabwe. The species exhibits sexual dimorphism in size. Males are larger, measuring 38 cm (15 in) in length and weighing 340–635 g (12.0–22.4 oz), whereas females measure 33 cm (13 in) in length and weigh 340–549 g (12.0–19.4 oz). The species has barred underparts (in contrast to the related Natal spurfowl) and a conspicuous yellow eye-ring.

Taxonomy The red-billed spurfowl was described in 1838 by the English naturalist George Robert Waterhouse from specimens collected by James Edward Alexander on his expedition to Namaqualand and Damaraland. Waterhouse coined the binomial name Francolinus adspersus and noted that the specimens had come near the Fish River in what is now Namibia. The specific epithet adspersus is Latin for "sprinkling". The species is now placed in the genus Pternistis that was introduced by the German naturalist Johann Georg Wagler in 1832. The red-billed spurfowl is considered as monotypic: the proposed subspecies mesicus is not recognised.

Worked examples

Example 1 — a first encounter with Red-billed spurfowl

Start with the simplest possible case. Write down what Red-billed spurfowl 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 Red-billed spurfowl 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 Red-billed spurfowl 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 Red-billed spurfowl

In research: Red-billed spurfowl 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 Red-billed spurfowl 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: Red-billed spurfowl is common in secondary-school and first-year university syllabi. It links to neighbouring topics Birds described in 1838, Birds of Southern Africa, Galliformes stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Red-billed spurfowl 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.
