Reference excerpt

Order: Apodiformes Family: Trochilidae Hummingbirds are small birds capable of hovering in mid-air due to the rapid flapping of their wings. They are the only birds that can fly backwards. Unless otherwise noted, all species listed below are considered to occur regularly in North America as permanent residents, summer or winter residents or visitors, or migrants. The following codes are used to designate some species:

(A) Accidental - occurrence based on one or two (rarely more) records, and unlikely to occur regularly (C) Casual - occurrence based on two or a few records, with subsequent records not improbable (E) Extinct - a recent species that no longer exists (Ex) Extirpated - a species which no longer occurs in North America, but populations still exist elsewhere (I) Introduced - a population established solely as result of direct or indirect human intervention; synonymous with non-native and non-indigenous Conservation status - IUCN Red List of Threatened Species:

EX - Extinct, EW - Extinct in the wild CR - Critically endangered, EN - Endangered, VU - Vulnerable NT - Near threatened, LC - Least concern DD - Data deficient, NE - Not evaluated (v. 2013.2, the data is current as of March 5, 2014) and Endangered Species Act:

E - endangered, T - threatened XN, XE - experimental non essential or essential population E(S/A), T(S/A) - endangered or threatened due to similarity of appearance (including taxa not necessarily found in the United States, the data is current as of June 8, 2012.)

Worked examples

Example 1 — a first encounter with List of hummingbirds of North America

Start with the simplest possible case. Write down what List of hummingbirds of North America claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 hummingbirds of North America 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 hummingbirds of North America 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 hummingbirds of North America

In research: List of hummingbirds of North America appears in science 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 hummingbirds of North America 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 hummingbirds of North America is common in secondary-school and first-year university syllabi. It links to neighbouring topics Hummingbirds, Lists of birds of North America, so understanding it makes those chapters shorter.
In everyday life: Look for List of hummingbirds of North America 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.
