Wetar ground dove

Wetar ground 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 Wetar ground dove rather than just read about it. In short: The Wetar ground dove (Pampusana hoedtii) is a species of bird in the family Columbidae found on Wetar, Indonesia, and on Timor. Its natural habitats are monsoon forests and gallery forests, and possibly woodland and bamboos.

Key takeaways

Wetar ground 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 Wetar ground dove to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

The Wetar ground dove (Pampusana hoedtii) is a species of bird in the family Columbidae found on Wetar, Indonesia, and on Timor. Its natural habitats are monsoon forests and gallery forests, and possibly woodland and bamboos. Threatened by habitat loss and hunting, the species is assessed as endangered by the IUCN.

Taxonomy In 1871, Hermann Schlegel described the species as Leptoptila hoedtii from Wetar. The species is monotypic. It has been moved from the genus Gallicolumba to Alopecoenas Sharpe, 1899. The name of the genus was changed in 2019 to Pampusana Bonaparte, 1855 as this name has priority. The specific epithet is derived from Dirk Samuel Hoedt, a Dutch collector who owned plantations in the East Indies.

Description Body length is about 27 cm (11 in) long. The male bird has a blue-grey head and a greyish white throat. The breast is pale cream, and the belly is blackish. The hindneck is reddish brown. The back and rump are rufous. Tail feathers are dark olive-brown, and there is a purple patch on the sides of the breast and the lesser covert feathers. The beak is black, and the feet are reddish violet. The female's head, neck and breast are rusty chestnut. Its upperparts and belly are olive-brown.

Distribution and habitat The species is found in Wetar and Timor. Fewer than 20 birds were collected on Wetar around 1900, and there were many records in 2008 and 2009. In Timor-Leste, four or five birds were recorded near the border with Indonesia in 2005. There are records from only three localities in West Timor. It is found at elevations up to 950 m (3,120 ft). Its habitats are monsoon forests and gallery forests, and possibly woodland and bamboos.

Behaviour The Wetar ground dove has been observed eating Ficus fruits on the ground. It appears to breed in the dry season, nesting in the canopy. It has been recorded calling from the canopy, giving a soft whu-wup call, sometimes with a du du-wup before it or a trrr after it.

Status The population size on Wetar is estimated to be less than 10,000 birds and may be less than 3000. The global population size of the Wetar ground dove is estimated at 1500–7000 mature individuals, or 2500–9999 total individuals. The population is rapidly declining. Threats to the species include habitat loss and hunting. There is much habitat destruction and hunting on Timor. On Wetar, there is less hunting because of the island's inaccessibility, but forest clearance may threaten the species. Mining and road-building may also increase. The International Union for Conservation of Nature has assessed its conservation status as endangered. Protected areas in West Timor and Wetar have been proposed.

Worked examples

Example 1 — a first encounter with Wetar ground dove

Start with the simplest possible case. Write down what Wetar ground 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 Wetar ground 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 Wetar ground 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 Wetar ground dove

In research: Wetar ground 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 Wetar ground 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: Wetar ground dove is common in secondary-school and first-year university syllabi. It links to neighbouring topics Birds described in 1871, Birds of Timor, Birds of Wetar, so understanding it makes those chapters shorter.
In everyday life: Look for Wetar ground 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.
