List of critically endangered birds

List of critically endangered birds 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 List of critically endangered birds rather than just read about it. In short: As of December 2019, the International Union for Conservation of Nature (IUCN) listed 223 critically endangered avian species, including 19 which are tagged as possibly extinct or possibly extinct in the wild. 2% of all evaluated avian species are listed as critically endangered. No subpopulations of birds have been evaluated by the IUCN.

Key takeaways

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

Reference excerpt

As of December 2019, the International Union for Conservation of Nature (IUCN) listed 223 critically endangered avian species, including 19 which are tagged as possibly extinct or possibly extinct in the wild. 2% of all evaluated avian species are listed as critically endangered. No subpopulations of birds have been evaluated by the IUCN. Additionally 55 avian species (0.48% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. While the category of data deficient indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of attention as threatened taxa, at least until their status can be assessed". This is a complete list of critically endangered avian species evaluated by the IUCN. Species considered possibly extinct by the IUCN are marked as such. Where possible common names for taxa are given while links point to the scientific name used by the IUCN.

Worked examples

Example 1 — a first encounter with List of critically endangered birds

Start with the simplest possible case. Write down what List of critically endangered birds 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 List of critically endangered birds 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 List of critically endangered birds 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 List of critically endangered birds

In research: List of critically endangered birds 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 List of critically endangered birds 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: List of critically endangered birds is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bird conservation, IUCN Red List critically endangered species, Lists of animals by conservation status, so understanding it makes those chapters shorter.
In everyday life: Look for List of critically endangered birds 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.
