Purple-naped lory

Purple-naped lory 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 Purple-naped lory rather than just read about it. In short: The purple-naped lory (Lorius domicella) is a species of parrot in the family Psittaculidae. It is forest-dwelling endemic to the islands of Seram, Ambon, and perhaps also Haruku and Saparua, South Maluku, Indonesia.

Key takeaways

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

Reference excerpt

The purple-naped lory (Lorius domicella) is a species of parrot in the family Psittaculidae. It is forest-dwelling endemic to the islands of Seram, Ambon, and perhaps also Haruku and Saparua, South Maluku, Indonesia. It is considered endangered, the main threat being from trapping for the cage-bird trade.

Taxonomy The purple-naped lory was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Psittacus domicella. The specific epithet domicella is Medieval Latin meaning "damsel". Linnaeus based his description on "The second Black-capped Lory" that had been described and illustrated in 1751 by the English naturalist George Edwards in his book A Natural History of Uncommon Birds. The specimen had been brought to London from the East Indies and Edwards was able made a drawing of it at the home of the naturalist and collector Hans Sloane. Linnaeus specified the locality as "Asia", but this is now taken to be Ambon Island in the Maluku Islands. The purple-naped lory is now placed in the genus Lorius that was introduced in 1825 by the Irish zoologist Nicholas Aylward Vigors. The species is monotypic: no subspecies are recognised.

Description

The purple-naped lory is 28 cm (11 in) long. It is mostly red with an all red tail that fades to darker red towards the tip. The top of its head is black, which fades to purple on the back of its neck. It has green wings, blue thighs, and a variable approximately transverse yellow band across the chest. It has an orange beak, dark-grey eyerings, and orange-red irises. Juveniles have a brown beak, grey-white eyerings, brown irises, a wider yellow band across the chest, and a more extensive purple patch on the back of neck.

Worked examples

Example 1 — a first encounter with Purple-naped lory

Start with the simplest possible case. Write down what Purple-naped lory 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 Purple-naped lory 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 Purple-naped lory 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 Purple-naped lory

In research: Purple-naped lory 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 Purple-naped lory 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: Purple-naped lory is common in secondary-school and first-year university syllabi. It links to neighbouring topics Animal taxa named by Carl Linnaeus, Birds described in 1758, Birds of the Maluku Islands, so understanding it makes those chapters shorter.
In everyday life: Look for Purple-naped lory 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.
