Black pitohui

Black pitohui 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 Black pitohui rather than just read about it. In short: The black pitohui (Melanorectes nigrescens) is a species of bird in the monotypic genus of Melanorectes in the family Pachycephalidae. It is found throughout the highlands of New Guinea.

Key takeaways

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

Reference excerpt

The black pitohui (Melanorectes nigrescens) is a species of bird in the monotypic genus of Melanorectes in the family Pachycephalidae. It is found throughout the highlands of New Guinea. Its natural habitat is subtropical or tropical moist lowland forests.

Taxonomy and systematics The black pitohui was originally described in the genus Rectes (a synonym for the genus Pitohui) and re-classified to Melanorectes in 2013. Alternate names include black whistler and dusky pitohui.

Subspecies The following six subspecies are recognized:

M. n. nigrescens – (Schlegel, 1871): Found in northwestern New Guinea M. n. wandamensis – (Hartert, 1930): Found in the Wandammen Peninsula (western New Guinea) M. n. meeki – (Rothschild & Hartert, 1913): Originally described as a separate species in the genus Pitohui. Found in west-central New Guinea M. n. buergersi – (Stresemann, 1922): Found in northern and east-central New Guinea M. n. harterti – Reichenow, 1911: Originally described as a separate species. Found in northeastern New Guinea M. n. schistaceus – (Reichenow, 1900): Found in southeastern New Guinea

Worked examples

Example 1 — a first encounter with Black pitohui

Start with the simplest possible case. Write down what Black pitohui 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 Black pitohui 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 Black pitohui 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 Black pitohui

In research: Black pitohui 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 Black pitohui 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: Black pitohui is common in secondary-school and first-year university syllabi. It links to neighbouring topics Birds described in 1871, Birds of the New Guinea Highlands, Corvides stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Black pitohui 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.
