Olive-winged trumpeter

Olive-winged trumpeter 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 Olive-winged trumpeter rather than just read about it. In short: The olive-winged trumpeter (Psophia dextralis) is a species of bird in the family Psophiidae. It is found in the Amazon rainforest of Brazil, but only east of the Tapajós River and west of the Araguaia River.

Key takeaways

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

Reference excerpt

The olive-winged trumpeter (Psophia dextralis) is a species of bird in the family Psophiidae. It is found in the Amazon rainforest of Brazil, but only east of the Tapajós River and west of the Araguaia River. This species is listed as Endangered by the IUCN. While the IUCN currently regards Psophia dextralis as a full species, IOC and eBird/Clements taxonomies still regard the olive-winged trumpeter as a subspecies of dark-winged trumpeter (Psophia viridis) as (P. v. dextralis), typically under the common name "dusky-backed trumpeter".

Behavior The olive-winged trumpeter lives in dense lowland rainforest away from human contact.

Diet The olive-winged trumpeter's diet consists of fruit, small vertebrates, arthropods and carrion.

Threats The olive-winged trumpeter is threatened by deforestation and hunting.

Breeding The olive-winged trumpeter's breeding is not well documented; all that is known is that its eggs are large.

Worked examples

Example 1 — a first encounter with Olive-winged trumpeter

Start with the simplest possible case. Write down what Olive-winged trumpeter 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 Olive-winged trumpeter 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 Olive-winged trumpeter 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 Olive-winged trumpeter

In research: Olive-winged trumpeter 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 Olive-winged trumpeter 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: Olive-winged trumpeter is common in secondary-school and first-year university syllabi. It links to neighbouring topics Birds described in 1934, Gruiformes stubs, IUCN Red List endangered species, so understanding it makes those chapters shorter.
In everyday life: Look for Olive-winged trumpeter 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.
