Woodford's rail

Woodford's rail 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 Woodford's rail rather than just read about it. In short: Woodford's rail (Gallirallus woodfordi), also known as the Guadalcanal rail, is a species of flightless bird and large rail in the family Rallidae. Taxonomy This species has been placed in various different genera, including Eulabeornis, Rallina, Rallus, Nesoclopeus, and Hypotaenidia.

Key takeaways

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

Reference excerpt

Woodford's rail (Gallirallus woodfordi), also known as the Guadalcanal rail, is a species of flightless bird and large rail in the family Rallidae.

Taxonomy This species has been placed in various different genera, including Eulabeornis, Rallina, Rallus, Nesoclopeus, and Hypotaenidia. There are three distinct subspecies, which may represent individual species: G. w. tertius (Bougainville Island) G. w. immaculatus (Santa Isabel Island) G. w. woodfordi (Guadalcanal Island)

Description Woodford's rail is a large, robust, and flightless rail. It is about 30 cm (12 in) in length and weighs between 410–670 g (0.90–1.48 lb). It is mostly a dark brown, gray, or black in coloration. It can run rapidly and uses its wings when trying to escape danger.

Distribution and habitat It is endemic to the Solomon Islands archipelago. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical swamps, rivers, freshwater lakes, freshwater marshes, and rural gardens.

Behavior On Santa Isabel, it feeds on worms, insects, reptiles, amphibians, and snails, as well as plant material. The other populations are likely similar. Its nest is made of plants and is about 25 cm (9.8 in) across. It lays clutches of two to six eggs, which are oval and creamy-buff with blotches and spots. These eggs measure about 45 mm × 33 mm (1.8 in × 1.3 in) on Bougainville Island, and are reportedly 30–40 mm (1.2–1.6 in) long on Santa Isabel.

Status and conservation It is currently threatened by habitat loss and was the only surviving species of the genus Nesoclopeus. However, recent genetic evidence finds that the species is nested within Gallirallus, as sister taxon to the Guam rail.

Worked examples

Example 1 — a first encounter with Woodford's rail

Start with the simplest possible case. Write down what Woodford's rail 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 Woodford's rail 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 Woodford's rail 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 Woodford's rail

In research: Woodford's rail 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 Woodford's rail 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: Woodford's rail is common in secondary-school and first-year university syllabi. It links to neighbouring topics Birds described in 1889, Birds of the Solomon Islands, Gallirallus, so understanding it makes those chapters shorter.
In everyday life: Look for Woodford's rail 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.
