Singing quail

Singing quail 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 Singing quail rather than just read about it. In short: The singing quail (Dactylortyx thoracicus) is a species of bird in the family Odontophoridae, the New World quail. It is found in Belize, El Salvador, Guatemala, Honduras, and Mexico.

Key takeaways

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

Reference excerpt

The singing quail (Dactylortyx thoracicus) is a species of bird in the family Odontophoridae, the New World quail. It is found in Belize, El Salvador, Guatemala, Honduras, and Mexico.

Taxonomy and systematics The singing quail is the only member of its genus and has 11 subspecies. Several other subspecies have been proposed but have not been validated; those forms are included within the 11 accepted subspecies.

Description The singing quail is 20 to 23 cm (7.9 to 9.1 in) long. Males weigh 180 to 266 g (6.3 to 9.4 oz) and females 115 to 206 g (4.1 to 7.3 oz). The smallest birds are found near sea level and the largest in the mountains. Adult males of the nominate subspecies have a dark brown crown, a buff and black "collar", and a tawny orange face with a black streak behind the eye. The back and wings are mottled gray and brown with thin white streaks; the rump is olive brown or gray and has black vermiculation. The breast and belly are grayish brown with white streaks and the lower belly is white. The female has a gray face and white throat and the breast and flanks are paler brown. Juveniles are similar to females but with blackish spots on the underparts. There is much variation among the other subspecies but in general those in mountain forests are darker than those in dryer lowlands.

Distribution and habitat The singing quail is found in several separate areas in northern, western, and southern Mexico; the Yucatán Peninsula; northern Belize; much of Guatemala, and spottily in El Salvador and Honduras. In general it inhabits the floor of forests with sparse undergrowth; it is also found in older secondary forest, at the edges of old-growth forest, in clear cuts, and coffee plantations. Forest types include subtropical montane forest and cloudforest. In elevation it ranges from sea level to at least 3,000 m (9,800 ft).

Behavior

Feeding The singing quail often forages in coveys of three to five birds but groups of up to 12 have been observed. It scratches for food in leaf litter and soil, feeding on bulbs, seeds, and insects.

Breeding The singing quail's breeding season appears to span from February to October. Broods of two to four have been recorded in Yucatán. Little else is known about its breeding phenology.

Vocalization

The singing quail has a "[l]oud, far-carrying, rhythmic song". It "commences with a series of hesitant, plaintive whistles, which increase in frequency and pitch into a rapidly delivered series, on varying pitch" and may be sung by several members of a covey. Coveys also give a weak twittering contact call.

Status The IUCN has assessed the singing quail as being of Least Concern. It appears to have a population exceeding 100,000 birds, is locally common, and is "apparently more capable of withstanding habitat destruction and fragmentation than other quails" of Middle America. However, "[t]hreats include deforestation, and possibly hunting and grazing in forests."

Worked examples

Example 1 — a first encounter with Singing quail

Start with the simplest possible case. Write down what Singing quail 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 Singing quail 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 Singing quail 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 Singing quail

In research: Singing quail 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 Singing quail 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: Singing quail is common in secondary-school and first-year university syllabi. It links to neighbouring topics Birds described in 1848, Birds of Central America, Birds of El Salvador, so understanding it makes those chapters shorter.
In everyday life: Look for Singing quail 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.
