Thick-billed green pigeon

Thick-billed green pigeon 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 Thick-billed green pigeon rather than just read about it. In short: The thick-billed green pigeon (Treron curvirostra) is a species of bird in the family Columbidae. Taxonomy The thick-billed green pigeon was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae.

Key takeaways

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

Reference excerpt

The thick-billed green pigeon (Treron curvirostra) is a species of bird in the family Columbidae.

Taxonomy The thick-billed green pigeon was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with all the other doves and pigeons in the genus Columba and coined the binomial name Columba curvirostra. Gmelin based his description on the "Hook-billed Pigeon" from the "island of Tanna in the South Seas" that had been described and illustrated in 1783 by the English ornithologist John Latham. Latham was mistaken in believing that his specimen had come from the island of Tanna in the New Hebrides. The type locality was designated as the Malay Peninsula by Harry C. Oberholser in 1912. The thick-billed green pigeon is now placed with around 30 other green pigeons in the genus Treron that was introduced in 1816 by the French ornithologist Louis Pierre Vieillot. The genus name is from the Ancient Greek trērōn meaning "pigeon" or "dove". The specific epithet curvirostra combines the Latin curvus meaning "curved" with -rostris meaning "billed". Seven subspecies are recognized:

T. c. nipalensis (Hodgson, 1836) – central Nepal and northeast India through Myanmar to south Indochina T. c. hainanus Hartert, EJO & Goodson, 1918 – Hainan Island (off southeast China) T. c. curvirostra (Gmelin, JF, 1789) – Malay Peninsula, Sumatra, Borneo, Mindoro and Palawan group (northwest, southwest Philippines) T. c. haliplous Oberholser, 1912 – Simeulue (west of north Sumatra) T. c. pegus Oberholser, 1912 – Nias (west of north Sumatra) T. c. smicrus Oberholser, 1912 – Sipura, Siberut and Batu Islands (west of central Sumatra) T. c. hypothapsinus Oberholser, 1912 – Enggano Island (west of south Sumatra)

Description Rather small-sized pigeon being under 26 cm (10 in) as compared to other green pigeons. A thick pale greenish bill with red base, broad bluish-Green eye ring, grey crown and maroon mantle diagnostic. Wings have black primary and secondaries with yellow outer edge. Underside green in both sexes. Thighs dark green with whitish scales. Female has greenish undertail coverts with whitish scales. Males have maroon dorsum and dull chestnut undertail coverts.

Distribution and habitat It ranges across the eastern regions of the Indian subcontinent and Southeast Asia, stretching from the Eastern Himalayas to Borneo and Sumatra. Found across Bangladesh, Bhutan, Brunei, Cambodia, Hong Kong, India, Indonesia, Laos, Malaysia, Myanmar, Nepal, the Philippines, Singapore, Thailand, Tibet and Vietnam. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical mangrove forests.

Behaviour and ecology Known to feed on syconia of Figs walking slowly along the branches.

Worked examples

Example 1 — a first encounter with Thick-billed green pigeon

Start with the simplest possible case. Write down what Thick-billed green pigeon 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 Thick-billed green pigeon 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 Thick-billed green pigeon 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 Thick-billed green pigeon

In research: Thick-billed green pigeon 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 Thick-billed green pigeon 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: Thick-billed green pigeon is common in secondary-school and first-year university syllabi. It links to neighbouring topics Birds described in 1789, Birds of Eastern Himalaya, Birds of South China, so understanding it makes those chapters shorter.
In everyday life: Look for Thick-billed green pigeon 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.
