Heinroth's shearwater

Heinroth's shearwater 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 Heinroth's shearwater rather than just read about it. In short: Heinroth's shearwater (Puffinus heinrothi) is a poorly known seabird in the family Procellariidae. Probably a close relative of the little shearwater or Audubon's shearwater (with which it is sometimes considered conspecific), it is distinguished by a long and slender bill and a brown-washed underside.

Key takeaways

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

Reference excerpt

Heinroth's shearwater (Puffinus heinrothi) is a poorly known seabird in the family Procellariidae. Probably a close relative of the little shearwater or Audubon's shearwater (with which it is sometimes considered conspecific), it is distinguished by a long and slender bill and a brown-washed underside. This species is restricted to the seas around the Bismarck Archipelago and northern Solomon Islands. The breeding sites of the species have never been found, although reports of individuals (including recently fledged chicks) on Bougainville and Kolombangara strongly suggest that they breed there, possibly high in the mountains (an inference based on the breeding behaviour of close relatives). There is very little information about the species and it is uncertain if it is threatened or in decline.

Worked examples

Example 1 — a first encounter with Heinroth's shearwater

Start with the simplest possible case. Write down what Heinroth's shearwater 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 Heinroth's shearwater 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 Heinroth's shearwater 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 Heinroth's shearwater

In research: Heinroth's shearwater 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 Heinroth's shearwater 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: Heinroth's shearwater is common in secondary-school and first-year university syllabi. It links to neighbouring topics Birds described in 1919, Birds of Bougainville Island, Birds of the Bismarck Archipelago, so understanding it makes those chapters shorter.
In everyday life: Look for Heinroth's shearwater 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.
