Western dwarf hornbill

Western dwarf hornbill 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 Western dwarf hornbill rather than just read about it. In short: The western dwarf hornbill (Horizocerus hartlaubi) is a species of hornbill in the family Bucerotidae. It is widely spread across the African tropical rainforest.

Key takeaways

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

Reference excerpt

The western dwarf hornbill (Horizocerus hartlaubi) is a species of hornbill in the family Bucerotidae. It is widely spread across the African tropical rainforest. It was formerly considered to be conspecific with the eastern dwarf hornbill (Horizocerus granti) with the English name "black dwarf hornbill".

Taxonomy The western dwarf hornbill was formally described in 1861 by the English ornithologist John Gould based on a specimen from "Western Africa". Gould coined the binomial name Toccus hartlaubi. The specific epithet was chosen to honour of the German ornithologist Gustav Hartlaub. This species was previously assigned to the genus Tockus but is now placed in the genus Horizocerus that was introduced in 1899 by the American ornithologist Harry C. Oberholser. The western dwarf hornbill was formerly considered to be conspecific with the eastern dwarf hornbill (Horizocerus granti) with the English name "black dwarf hornbill".

Description It is black with a curved beak and a wide white brow above its eye.

Worked examples

Example 1 — a first encounter with Western dwarf hornbill

Start with the simplest possible case. Write down what Western dwarf hornbill 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 Western dwarf hornbill 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 Western dwarf hornbill 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 Western dwarf hornbill

In research: Western dwarf hornbill 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 Western dwarf hornbill 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: Western dwarf hornbill is common in secondary-school and first-year university syllabi. It links to neighbouring topics Birds described in 1861, Bucerotiformes stubs, Horizocerus, so understanding it makes those chapters shorter.
In everyday life: Look for Western dwarf hornbill 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.
