Providence blue pigeon

Providence blue 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 Providence blue pigeon rather than just read about it. In short: The Providence blue pigeon (Alectroenas sp.), also known as the Farquhar Islands blue pigeon or small blue pigeon, is an extinct species of bird that lived on Farquhar, Providence, and St. Pierre in the Seychelles.

Key takeaways

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

Reference excerpt

The Providence blue pigeon (Alectroenas sp.), also known as the Farquhar Islands blue pigeon or small blue pigeon, is an extinct species of bird that lived on Farquhar, Providence, and St. Pierre in the Seychelles.

Description The Providence blue pigeon was a species of blue pigeon that most likely looked very similar to the Seychelles blue pigeon. It may even have been the same species as the Seychelles blue pigeon, although it is possible that it was a distinct species. It nested on Mapou trees and other similar trees. In 1821–1822 it was said that they were in great abundance in Farquhar. They were known to be incredibly tame, and nearly impossible to disturb.

History In an excerpt from a document from Fairfax Moresby, he mentions "small blue pigeons", of which today none are known to inhabit the island.

A document about voyages in the southwest Indian Ocean in 1821–22, written by Captain Fairfax Moresby: "Jean de Nova i.e. Farquhar and Providence ... like the Amirantes, Coetivy and Alphonse are the resort of Millions of Birds of which, the Frigate Bird, the Fou, a beautiful small white gull, a variety of various coloured Gannet, and the Tropic Bird are the principle: In S. Pierre and Providence a species of small blue pigeon are in great abundance, and so seldom disturbed that they do not fly at Man's approach, but are knock'd down with Sticks, we found them excessively good eating, these birds build and nest on the Mapou tree and other Dwarf trees which cover the surface of the islands..." In 1968, David Stoddart surveyed Farquhar but did not sight any blue pigeon species. It is unknown what drove them to extinction.

Worked examples

Example 1 — a first encounter with Providence blue pigeon

Start with the simplest possible case. Write down what Providence blue 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 Providence blue 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 Providence blue 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 Providence blue pigeon

In research: Providence blue 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 Providence blue 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: Providence blue pigeon is common in secondary-school and first-year university syllabi. It links to neighbouring topics Alectroenas, Columbiformes stubs, Extinct birds of Indian Ocean islands, so understanding it makes those chapters shorter.
In everyday life: Look for Providence blue 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.
