Red-eared fruit dove

Red-eared fruit dove 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-eared fruit dove rather than just read about it. In short: The red-eared fruit dove (Ramphiculus fischeri) is a species of bird in the pigeon family. It is endemic to the island of Sulawesi, Indonesia.

Key takeaways

Red-eared fruit dove 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-eared fruit dove to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Red-eared fruit dove from memory before moving on to harder problems.

Reference excerpt

The red-eared fruit dove (Ramphiculus fischeri) is a species of bird in the pigeon family. It is endemic to the island of Sulawesi, Indonesia. This species was formerly placed in the genus Ptilinopus.

Distribution Its natural habitat is subtropical or tropical moist montane forests. They are found at elevations between 1,000–3,000 m (3,300–9,800 ft).

Subspecies Three subspecies are recognised; they differ in the colour of the upperparts:

R. f. fischeri (Brüggemann, F, 1876) – montane forest of northern Sulawesi. Wing coverts, back, rump and tail green. R. f. centralis (Meyer, AB, 1903) – montane forest of central and southeastern Sulawesi. Wing coverts, rump and tail green, back brown. R. f. meridionalis (Meyer, AB & Wiglesworth, LW, 1893) – southwestern Sulawesi (Lompobattang Massif). Rump and tail green, wing coverts and back brown. This subspecies has previously been treated as a separate species, the Lompobattang fruit dove (Ramphiculus meridionalis) by the HBW/BirdLife International taxonomy.

Status It is listed as least concern by the IUCN although their populations are currently decreasing.

Worked examples

Example 1 — a first encounter with Red-eared fruit dove

Start with the simplest possible case. Write down what Red-eared fruit dove 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-eared fruit dove 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-eared fruit dove 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-eared fruit dove

In research: Red-eared fruit dove 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-eared fruit dove 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-eared fruit dove is common in secondary-school and first-year university syllabi. It links to neighbouring topics Birds described in 1876, Columbiformes stubs, Endemic birds of Sulawesi, so understanding it makes those chapters shorter.
In everyday life: Look for Red-eared fruit dove 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.
