Northern variable pitohui

Northern variable 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 Northern variable pitohui rather than just read about it. In short: The northern variable pitohui (Pitohui kirhocephalus) is a species of pitohui in the family Oriolidae. It is found on New Guinea and a number of neighbouring islands.

Key takeaways

Northern variable 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 Northern variable pitohui to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Northern variable pitohui from memory before moving on to harder problems.

Reference excerpt

The northern variable pitohui (Pitohui kirhocephalus) is a species of pitohui in the family Oriolidae. It is found on New Guinea and a number of neighbouring islands. Its natural habitat is subtropical or tropical moist lowland forests. It is also one of the few known poisonous birds.

Taxonomy and systematics The northern variable pitohui was renamed from the variable pitohui in 2013 following the split of the Raja Ampat pitohui and the southern variable pitohui.

Subspecies Eleven subspecies are recognized:

Pitohui kirhocephalus kirhocephalus - (Lesson & Garnot, 1827): Found on eastern Vogelkop (north-western New Guinea) Pitohui kirhocephalus dohertyi - Rothschild & Hartert, 1903: Originally described as a separate species. Found in Wandammen area (north-western New Guinea) Pitohui kirhocephalus rubiensis - (Meyer, AB, 1884): Originally described as a separate species. Found from head of Cenderawasih Bay to Triton Bay (western New Guinea) Pitohui kirhocephalus brunneivertex - Rothschild, 1931: Found on eastern coast of Cenderawasih Bay (north-western New Guinea) Pitohui kirhocephalus decipiens - (Salvadori, 1878): Originally described as a separate species. Found on the Onin Peninsula (south-western New Guinea) Pitohui kirhocephalus adiensis - Mees, 1964: Found on Adi Island (off south-western New Guinea) Pitohui kirhocephalus carolinae - Junge, 1952: Found in the Etna Bay region of south-western New Guinea Pitohui kirhocephalus jobiensis - (Meyer, AB, 1874): Originally described as a separate species. Found on Kurudu Island and Yapen (off north-western New Guinea) Pitohui kirhocephalus meyeri - Rothschild & Hartert, 1903: Originally described as a separate species. Found on the Mamberamo coast (northern New Guinea) Pitohui kirhocephalus senex - Stresemann, 1922: Found in the upper Sepik region (northern New Guinea) Pitohui kirhocephalus brunneicaudus - (Meyer, AB, 1891): Originally described as a separate species. Found in the lower Sepik region to Astrolabe Bay (northern New Guinea)

Worked examples

Example 1 — a first encounter with Northern variable pitohui

Start with the simplest possible case. Write down what Northern variable 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 Northern variable 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 Northern variable 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 Northern variable pitohui

In research: Northern variable 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 Northern variable 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: Northern variable pitohui is common in secondary-school and first-year university syllabi. It links to neighbouring topics Birds described in 1827, Birds of northern New Guinea, Corvides stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Northern variable 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.
