Philippine collared dove

Philippine collared dove 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 collared dove rather than just read about it. In short: The Philippine collared dove (Streptopelia dusumieri) is a species of bird in the family Columbidae. It was formerly considered a subspecies of the island collared dove (S. bitorquata).

Key takeaways

Philippine collared dove 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 collared dove to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Philippine collared dove from memory before moving on to harder problems.

Reference excerpt

The Philippine collared dove (Streptopelia dusumieri) is a species of bird in the family Columbidae. It was formerly considered a subspecies of the island collared dove (S. bitorquata). The species occurs in the Philippines where it is called locally as bato-bato de collar. It has also been introduced into Guam and the Northern Mariana Islands, although the population on Guam has been severely reduced by introduced brown tree snakes. Its natural habitats are open grassland and agricultural land with trees and scrub. It was formerly considered a subspecies of the island collared dove. This species is threatened and is now rare in its native range due to interspecific competition from the Spotted dove and Red collared dove.

Description and taxonomy Was considered conspecific with the Sunda collared dove as part of the Island collared dove species complex. Differs in a stronger contrast black and white tail but a weaker contrast in the undertail, a paler collar with a green sheen and scales and no white band, rusty pink plummage, shorter bill and a different song. This species is monotypic and has no subspecies.

Ecology and behavior This species' diet has yet to be studied comprehensively but it is presumed to be the same as the Sunda collared dove which feeds mostly on seeds and feeds from the ground. It is typically observed singly or in pairs. Breeding season is March to May. Nests 1 to 7 meters from the ground in branches in low trees at clearings, fishponds and mangroves. Nest is described as a typical flimsy dove nest consisting on messily arranged twigs. Clutch size is 2 to 3 eggs.

Habitat and conservation status An open country species inhabiting grassland and agricultural land with trees and scrub, while introduced populations are found in urban areas. Breeding has been recorded in March and May in the Philippines. IUCN has assessed this bird as vulnerable with its population continuing to decline. Its main threat is heavy interspecific competition from spotted doves and red collared doves. In Guam where the birds are still fairly common, nest success rate is just 2 to 5% in urban areas and 0 to 3% in forest habitat. Conservation actions proposed to clarify nature and extent of threat from spotted doves and red collared doves are identification of remaining strongholds, monitoring of population trends, and assessment of desirability and feasibility of the control of competing species.

Worked examples

Example 1 — a first encounter with Philippine collared dove

Start with the simplest possible case. Write down what Philippine collared dove 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 collared dove 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 collared dove 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 collared dove

In research: Philippine collared dove 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 collared dove 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 collared dove is common in secondary-school and first-year university syllabi. It links to neighbouring topics Birds described in 1823, Columbiformes stubs, Endemic birds of the Philippines, so understanding it makes those chapters shorter.
In everyday life: Look for Philippine collared dove 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.
