Philippine serpent eagle

Philippine serpent eagle 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 Philippine serpent eagle rather than just read about it. In short: The Philippine serpent eagle (Spilornis holospilus) is an eagle found in the major islands of the Philippines. It is sometimes treated as a race of the crested serpent eagle (Spilornis cheela).

Key takeaways

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

Reference excerpt

The Philippine serpent eagle (Spilornis holospilus) is an eagle found in the major islands of the Philippines. It is sometimes treated as a race of the crested serpent eagle (Spilornis cheela). This species is usually found in forest clearings, open woodlands, and sometimes in cultivated lands with scattered trees. It is endemic to the Philippines. The species is found on most part of the major islands, except for Palawan. It is illegal to hunt, capture or possess Philippine serpent eagles under Philippine Law RA 9147.

Description and taxonomy It has a length of 47 to 53 cm and a wingspan of 105 to 120 cm. This species is monotypic.

Ecology and behavior The bird feeds on amphibians, reptiles and other live prey. Not much is known about its breeding habits. A female was collected with a single egg in its oviducts in April of 2020.

Habitat and conservation status Its natural habitats are tropical moist lowland forest, montane forest, second growth and cultivated areas up to 2,500 meters above sea level. The IUCN has classified the species as being of Least Concern as it has a large range and it is common throughout its range and appears to adapt to second growth. Populations are still declining due to habitat loss due to slash and burn farming, mining, illegal logging and habitat conversion, hunting and poaching for the illegal wildlife trade. It is found in multiple protected areas such as Pasonanca Natural Park, Bataan National Park, Mount Banahaw, Mount Kitanglad. Mount Apo, Pasonanca Natural Park and Northern Sierra Madre Natural Park but like all areas in the Philippines, protection is lax and deforestation continues despite this protection on paper.

Worked examples

Example 1 — a first encounter with Philippine serpent eagle

Start with the simplest possible case. Write down what Philippine serpent eagle 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 Philippine serpent eagle 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 Philippine serpent eagle 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 Philippine serpent eagle

In research: Philippine serpent eagle 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 Philippine serpent eagle 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: Philippine serpent eagle is common in secondary-school and first-year university syllabi. It links to neighbouring topics Accipitriformes stubs, Birds described in 1831, Eagles, so understanding it makes those chapters shorter.
In everyday life: Look for Philippine serpent eagle 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.
