It is a small hawk that occurs in Puerto Rico, inhabiting the Toro Negro State Forest.

Key takeaways

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

Reference excerpt

The Puerto Rican broad-winged hawk (Buteo platypterus brunnescens) is an endangered subspecies of the broad-winged hawk (B. platypterus). It is a small hawk that occurs in Puerto Rico, inhabiting the Toro Negro State Forest. It is restricted to the montane forests of the Cordillera Central, Sierra de Cayey, and Sierra de Luquillo. It was federally listed as endangered on September 9, 1994. This species occurs in elfin woodland, sierra palm, caimitillo-granadillo, and tabonuco forest types of the Río Abajo Commonwealth Forest, Carite Commonwealth Forest, and El Yunque National Forest as well as within hardwood plantations, shade coffee plantations, and mature secondary forests. In 1994, the Puerto Rican broad-winged hawk population was estimated at 125 individuals islandwide. Its Spanish common name is guaragüao de bosque.

Worked examples

Example 1 — a first encounter with Puerto Rican broad-winged hawk

Start with the simplest possible case. Write down what Puerto Rican broad-winged hawk 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 Puerto Rican broad-winged hawk 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 Puerto Rican broad-winged hawk 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 Puerto Rican broad-winged hawk

In research: Puerto Rican broad-winged hawk 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 Puerto Rican broad-winged hawk 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: Puerto Rican broad-winged hawk is common in secondary-school and first-year university syllabi. It links to neighbouring topics Accipitriformes stubs, Birds described in 1935, Buteo, so understanding it makes those chapters shorter.
In everyday life: Look for Puerto Rican broad-winged hawk 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.
