Subandean parakeet

Subandean parakeet 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 Subandean parakeet rather than just read about it. In short: The Subandean parakeet (Pyrrhura subandina), also known as the Sinú parakeet, is a bird in subfamily Arinae of the family Psittacidae, the African and New World parrots. BirdLife International's Handbook of the Birds of the World recognizes it as a full species.

Key takeaways

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

Reference excerpt

The Subandean parakeet (Pyrrhura subandina), also known as the Sinú parakeet, is a bird in subfamily Arinae of the family Psittacidae, the African and New World parrots. BirdLife International's Handbook of the Birds of the World recognizes it as a full species. The International Ornithological Committee (IOC), the South American Classification Committee of the American Ornithological Society, and the Clements taxonomy treat it as a subspecies of the painted parakeet (P. picta). A molecular genetic study published in 2023 found that the Subandean parakeet was sister to the Perija parakeet (Pyrrhura caeruleiceps).

Subspecies Two subspecies are recognised:

Azuero parakeet, P. s. eisenmanni Delgado, JA, 1985 – south-central Panama (Azuero Peninsula) Sinú parakeet, P. s. subandina Todd, WEC, 1917 – northwestern Colombia (lower Sinú River Valley); unrecorded since 1949 and possibly extinct The nominate subspecies, P. s. subandina, is only known with certainty from the Sinú Valley in northern Colombia. BirdLife International estimates that if the bird is not already extinct, no more than 50 likely exist. Despite extensive searches, there have been no confirmed records of the parakeet since 1949. Scientists know very little about the Sinú parakeet's reproductive physiology, nutritional needs, ecology, or behavior. There are 18 specimens known from four locations in Colombia, two of which have been deforested. The parakeet is among the 25 "most wanted lost" species that are the focus of Re:wild's "Search for Lost Species" initiative.

Worked examples

Example 1 — a first encounter with Subandean parakeet

Start with the simplest possible case. Write down what Subandean parakeet 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 Subandean parakeet 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 Subandean parakeet 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 Subandean parakeet

In research: Subandean parakeet 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 Subandean parakeet 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: Subandean parakeet is common in secondary-school and first-year university syllabi. It links to neighbouring topics Birds described in 1917, Birds of Colombia, IUCN Red List critically endangered species, so understanding it makes those chapters shorter.
In everyday life: Look for Subandean parakeet 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.
