Red-naped shaheen

Red-naped shaheen is a science 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 Red-naped shaheen rather than just read about it. In short: The red-naped shaheen (Falco peregrinus babylonicus) is a non-migratory subspecies of the peregrine falcon. The subspecies is distributed from Mongolia, Kazakhstan to India and Iran.

Key takeaways

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

Reference excerpt

The red-naped shaheen (Falco peregrinus babylonicus) is a non-migratory subspecies of the peregrine falcon. The subspecies is distributed from Mongolia, Kazakhstan to India and Iran.

Description Adults are paler than other subspecies of peregrine falcon. They show a greyish blue colour on their back. forehead and nape are rufous and crown is more dark. Their narrow moustashes have the same colour like their crown with rufous halo on edges. In comparison with other subspecies, F. p. babylonicus has fewer spots on chest, and abdomen and thighs with creamy background. After multiple moults the chest will be clear and a few V-shape spots remain on thighs and flanks. The tail has the same colour as the back, with darker barring. Juveniles have brown back and crown with paler and rufous-buff forehead. Their moustaches are dark brown with rufous-buff edges. Their chest and thighs are streaked and have vertical barrs with cream background. Their tail is brown with darker barrings. Flight feathers are longer in juveniles and after the first moulting they grow in the same size of adults. And after each moulting their lateral tail feathers grow lesser than the past year.

Etymology Linguists said that the Persian word شاهین (shaheen) is derived from the older world سئن (sa'en), meaning "big bird of prey".

Worked examples

Example 1 — a first encounter with Red-naped shaheen

Start with the simplest possible case. Write down what Red-naped shaheen 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 Red-naped shaheen 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 Red-naped shaheen 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 Red-naped shaheen

In research: Red-naped shaheen 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 Red-naped shaheen 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: Red-naped shaheen is common in secondary-school and first-year university syllabi. It links to neighbouring topics Birds of India, Birds of Iran, Birds of Kazakhstan, so understanding it makes those chapters shorter.
In everyday life: Look for Red-naped shaheen 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.
