Tanna fruit dove

Tanna 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 Tanna fruit dove rather than just read about it. In short: The Tanna fruit dove (Ptilinopus tannensis) is a species of bird in the family Columbidae. It is endemic to Vanuatu.

Key takeaways

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

Reference excerpt

The Tanna fruit dove (Ptilinopus tannensis) is a species of bird in the family Columbidae. It is endemic to Vanuatu. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, and heavily degraded former forest.

Description The average length of the Tanna fruit dove is 28 – 30 cm. Its face is yellow and fades into dark green with touches of yellow towards its body. The males have a silver patch below their necks on each side of their bodies. The female Tanna fruit dove lacks the silver patches but has white on its lower body. Its legs are purply red, and it has a bluish-gray bill. The younger Tanna fruit doves are green with yellow rims on the end of each feather.

Population and conservations The Tanna fruit dove is monotypic. As of 2024, the population trend is decreasing. Although it is not globally threatened, the Tanna fruit dove is experiencing a slow decline due to the loss of suitable large trees. The current population size is unknown. It was previously considered near threatened but is now normally found in all habitats. The average generation length is 3.2 years. Threats to the bird include hunting, trapping, logging, and wood harvesting.

Distribution and habitat The Tanna fruit dove can be found in Vanuatu, a country in Oceania. This bird lives in degraded habitats that have fruit trees. The Tanna fruit dove can be found in a terrestrial or artificial forest. Its habitat types are forests, open woodlands, parklands, plantations, and gardens. It is most commonly found in lowlands but can also be found in mountains under 1500 m. The Tanna fruit doves' upper elevation limit is 500 meters. The Tanna fruit dove travels between islands. Their movement patterns are nomadic because of the ripening of fruit crops.

Diet and feeding The Tanna fruit doves are frugivorous, meaning an animal that feeds on fruit. Their most common foods include strangler figs and mahogany trees. They feed mainly in the canopies. They do their feeding in dense areas where it's difficult to be spotted and they feed by themselves, in pairs, or in small groups.

Nests and reproduction The Tanna fruit doves' nests are thin and made up of twigs, typically found high up in trees. They lay one white egg. Both the mom and the dad care for the young.

Vocalizations The Tanna fruit dove's call is a repeated single coo every 2.5 seconds. The note gradually increases in volume and then has a sudden end.

Worked examples

Example 1 — a first encounter with Tanna fruit dove

Start with the simplest possible case. Write down what Tanna 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 Tanna 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 Tanna 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 Tanna fruit dove

In research: Tanna 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 Tanna 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: Tanna fruit dove is common in secondary-school and first-year university syllabi. It links to neighbouring topics Birds described in 1790, Birds of Vanuatu, Columbiformes stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Tanna 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.
