Grey-breasted partridge

Grey-breasted partridge 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 Grey-breasted partridge rather than just read about it. In short: The grey-breasted partridge (Arborophila orientalis), also known as the white-faced hill partridge, or Horsfield's hill partridge, is a bird species in the family Phasianidae. It is endemic to highland forest in the eastern salient of Java, Indonesia.

Key takeaways

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

Reference excerpt

The grey-breasted partridge (Arborophila orientalis), also known as the white-faced hill partridge, or Horsfield's hill partridge, is a bird species in the family Phasianidae. It is endemic to highland forest in the eastern salient of Java, Indonesia. Sightings have been mostly reported from frequently visited nature preserves such as Kawah Ijen in Banyuwangi. Measuring 28 cm (11 in), this species is a stocky, short-legged bird. Its mostly grey plumage is barred on the lower back and tail. It has a black crown and nape, and conspicuous white forehead, cheeks and throat. Bare skin around the eyes is red. The bill is black and the legs are red. Some authorities include the Malayan, Roll's and Sumatran partridges as subspecies of the grey-breasted partridge. The grey-breasted partridge is threatened by habitat loss.

Worked examples

Example 1 — a first encounter with Grey-breasted partridge

Start with the simplest possible case. Write down what Grey-breasted partridge 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 Grey-breasted partridge 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 Grey-breasted partridge 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 Grey-breasted partridge

In research: Grey-breasted partridge 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 Grey-breasted partridge 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: Grey-breasted partridge is common in secondary-school and first-year university syllabi. It links to neighbouring topics Arborophila, Birds described in 1821, Endemic birds of Java, so understanding it makes those chapters shorter.
In everyday life: Look for Grey-breasted partridge 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.
