Guanacaste hummingbird

Guanacaste hummingbird 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 Guanacaste hummingbird rather than just read about it. In short: The Guanacaste hummingbird, also known as the Alfaro's hummingbird or Miravalles hummingbird (Saucerottia alfaroana), is a possibly extinct species of hummingbird known only from a holotype collected in 1895 at the Miravalles Volcano in Costa Rica. Taxonomy It is usually treated as a subspecies of the Indigo-capped hummingbird or a hybrid between two unknown hummingbird species, but analysis of the holotype suggests…

Key takeaways

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

Reference excerpt

The Guanacaste hummingbird, also known as the Alfaro's hummingbird or Miravalles hummingbird (Saucerottia alfaroana), is a possibly extinct species of hummingbird known only from a holotype collected in 1895 at the Miravalles Volcano in Costa Rica.

Taxonomy It is usually treated as a subspecies of the Indigo-capped hummingbird or a hybrid between two unknown hummingbird species, but analysis of the holotype suggests it is its own species.

Conservation It is possibly extinct, but the ecological stability of the area where the specimen was found indicates a possible undiscovered population still existing. The IUCN classifies it as critically endangered.

Worked examples

Example 1 — a first encounter with Guanacaste hummingbird

Start with the simplest possible case. Write down what Guanacaste hummingbird 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 Guanacaste hummingbird 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 Guanacaste hummingbird 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 Guanacaste hummingbird

In research: Guanacaste hummingbird 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 Guanacaste hummingbird 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: Guanacaste hummingbird is common in secondary-school and first-year university syllabi. It links to neighbouring topics Amazilia, Birds described in 1896, Controversial hummingbird taxa, so understanding it makes those chapters shorter.
In everyday life: Look for Guanacaste hummingbird 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.
