Plain pigeon

Plain 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 Plain pigeon rather than just read about it. In short: The plain pigeon (Patagioenas inornata) is a species of bird in the family Columbidae. It is found in the four Greater Antilles, on Cuba, Hispaniola (in the Dominican Republic and Haiti), Jamaica, and Puerto Rico.

Key takeaways

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

Reference excerpt

The plain pigeon (Patagioenas inornata) is a species of bird in the family Columbidae. It is found in the four Greater Antilles, on Cuba, Hispaniola (in the Dominican Republic and Haiti), Jamaica, and Puerto Rico. Its natural habitats are forest, woodland, coastal scrub, mangrove and swampy areas. It is threatened by habitat loss and illegal hunting.

Description

The plain pigeon is a large-bodied bird 38–41 cm (15–16 in) long that superficially resembles a large feral pigeon or a very plainly-plumaged band-tailed pigeon. At a distance it appears pale blue-gray overall. The head, hindneck, breast, and part of the folded wing are colored with a red-wine wash. When folded, the wing shows a white leading edge; in flight, it forms a conspicuous wing bar. The eyes have a pale yellow iris; the legs and feet are dark red, and the bill black. The female is slightly smaller and duller than the male. Juveniles are browner overall, with pale wing margins and dark eyes. On Jamaica, it can be confused with the Jamaican endemic ring-tailed pigeon P. caribaea, but that has a red eye, a gray wing lacking the wine-colored wash of plain pigeon, and a paler tail with an obvious dark blackish-gray band across the base of the tail.

Taxonomy The plain pigeon is thought to represent a superspecies with the red-billed pigeon (P. flavirostria) and the Maranon pigeon (P. oenops), found in Central and South America respectively; these two are however both smaller than plain pigeon at 32–37 cm (13–15 in). Three subspecies of the plain pigeon have been described and were formerly often accepted, with P. i. inornata from Cuba and Hispaniola, P. i. exigua from Jamaica, and P. i. wetmorei from Puerto Rico. However, there is no discernible difference between these, and the species is now treated as monotypic.

Status During the 1970s, the Puerto Rican population was on the brink of extinction. The ornithologist Richard C. Banks suggested it possibly did become extinct there, as there were no sightings on Puerto Rico between 1926 and 1958, with the current population a natural or human-assisted recolonization from Hispaniola; as with other species in the genus, it is capable of strong flight and could cross between the islands readily. A conservation program was introduced to save the species and now it numbers a few thousand individuals.

Worked examples

Example 1 — a first encounter with Plain pigeon

Start with the simplest possible case. Write down what Plain 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 Plain 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 Plain 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 Plain pigeon

In research: Plain 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 Plain 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: Plain pigeon is common in secondary-school and first-year university syllabi. It links to neighbouring topics Birds described in 1827, Birds of Haiti, Birds of the Dominican Republic, so understanding it makes those chapters shorter.
In everyday life: Look for Plain 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.
