Mamo

Mamo 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 Mamo rather than just read about it. In short: Mamo or woowoo is a common name for two species of extinct birds. Together with the extant ʻIʻiwi they make up the genus Drepanis.

Key takeaways

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

Reference excerpt

Mamo or woowoo is a common name for two species of extinct birds. Together with the extant ʻIʻiwi they make up the genus Drepanis. These nectarivorous finches were endemic to Hawaii but are now extinct. The Hawaiian name may be related to the name of the ʻōʻō (Moho nobilis), a bird with a similar appearance. Another name for the mamo was ʻōʻō-nuku-umu, meaning "ʻōʻō with the sucking beak". Two species are known.

Hawaiʻi mamo

The Hawaiʻi mamo (Drepanis pacifica) was about 9 in (23 cm) in length. Its plumage was glossy black with yellow rumps and thigh feathers and a small yellow shoulder patch. The tail was black and there was a white basal primary patch and white shafts along the primaries. The bill was long, curved and black. Legs were dark gray or black. This was a shy species that lived in the forest canopy and fed on the nectar of Lobelia species that possess curved, tubular flowers. Its call was a long, plaintive whistle. The bright golden-yellow feathers of the Hawaiʻi mamo were prized for the featherwork worn by the aliʻi (Hawaiian royalty). The famous yellow cloak of Kamehameha I is estimated to have taken the reigns of eight monarchs and the golden feathers of 80,000 Hawaiʻi mamos before it was completed. The Hawaiʻi mamo was last seen in 1899 near Kaūmana by a collector, H. W. Henshaw, who, as mentioned by Tim Flannery in his book, A Gap In Nature, shot and wounded a bird he was stalking, before it escaped him with another bird.

Black mamo

The black mamo (Drepanis funerea) was about 8 in (20 cm) in length and appeared similar to the Hawaiʻi mamo but was entirely black except for the white primary shafts on the wings. The bill was more sharply decurved than the former species and had a small yellowy spot near the base (on the operculum). When the bird fed the forehead would often become covered in pollen, making the forehead appear pale. The species fed on nectar from the flowers of Lobelia species and ʻōhiʻa lehua (Metrosideros polymorpha) at lower levels than the Hawaiʻi mamo. The bird was apparently curious and would approach observers. Its call was a clear flute-like whistle and a five or six note rollicking whistle. The black mamo was endemic to Molokaʻi and was last observed in 1907 by the collector Alanson Bryan, who had shot three birds. Tim Flannery quoted him as having written, "To my joy I found the mangled remains hanging in the tree in a thick bunch of leaves, six feet or more beyond where it had been sitting."

Worked examples

Example 1 — a first encounter with Mamo

Start with the simplest possible case. Write down what Mamo 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 Mamo 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 Mamo 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 Mamo

In research: Mamo 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 Mamo 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: Mamo is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bird common names, Drepanis, Endemic fauna of Hawaii, so understanding it makes those chapters shorter.
In everyday life: Look for Mamo 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.

Frequently asked questions

What is Mamo in simple terms?

Mamo or woowoo is a common name for two species of extinct birds. Together with the extant ʻIʻiwi they make up the genus Drepanis.

Why does Mamo matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Mamo?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
