Red-legged tinamou

Red-legged tinamou 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 Red-legged tinamou rather than just read about it. In short: The red-legged tinamou or red-footed tinamou, (Crypturellus erythropus) is a ground-dwelling bird found in the tropics and lower subtropics of northern South America. Description The red-legged tinamou is superficially similar to a quail to which it is not related as it, along with other tinamous, belongs in the Paleognathae.

Reference excerpt

The red-legged tinamou or red-footed tinamou, (Crypturellus erythropus) is a ground-dwelling bird found in the tropics and lower subtropics of northern South America.

Description The red-legged tinamou is superficially similar to a quail to which it is not related as it, along with other tinamous, belongs in the Paleognathae. Its total length is 27 to 32 cm (11–13 in). Its brownish upperparts and grey chest contrasts clearly with the buff belly. The back and wings are barred, but this is faint (often barely visible) in the males. Additionally, the amount of barring to the upperparts varies among the subspecies. It is the only tinamou in its range with rosy-red legs.

Behavior As other tinamous, it is recorded infrequently, except by its whistling voice. It has been recorded feeding on seeds, berries, snails, and insects. Little is known about its breeding behavior, but the glossy eggs are pale greyish-lavender with a variable amount of pink suffusion.

Etymology Crypturellus is formed from three Latin or Greek words/parts. kruptos meaning covered or hidden, oura meaning tail, and -ellus a Latin diminutive suffix. Therefore, Crypturellus means small hidden tail.

Taxonomy All tinamou are from the family Tinamidae, and in the larger scheme are also ratites. Unlike other ratites, tinamous can fly, although in general, they are not strong fliers. All ratites evolved from prehistoric flying birds, and tinamous are the closest living relative of these birds. Red-legged tinamou subspecies are:

C. e. erythropus located in eastern Venezuela, Guyana, Suriname, and northeastern Brazil. C. e. cursitans located east of the Andes in northern Colombia and northwestern Venezuela. C. e. spencei located in northern Venezuela. C. e. margaritae located on Margarita Island. C. e. saltuarius - Magdalena tinamou located in northeastern Colombia in Sierra de Ocaña. C. e. columbianus - Colombian tinamou located in tropical north central Colombia. C. e. idoneus - Santa Marta tinamou located in northeastern Colombia and northwestern Venezuela. The taxonomy, beyond this, remains unclear, with some authorities considering the taxa saltuarius, idoneus, and columbianus as monotypic species rather than subspecies of the red-legged tinamou. The SACC rejected a proposal to elevate these to species status, arguing that the presently available data fail to support the split. Additionally, several subspecies usually associated with the red-legged tinamou have been associated with other species in the past, especially the thicket tinamou, the Choco tinamou and the yellow-legged tinamou.

Range and habitat The red-legged tinamou lives in Guyana, Suriname, Colombia, Venezuela and northeastern Brazil, and on Margarita Island. It may also be found in French Guiana. Its favored habitat is dry forest, although it can be found in moist forest and lower elevation shrubland and grasslands. It prefers elevations below 1,300 m (4,300 ft).

Conservation The red-legged tinamou is uncommon to locally common in most of its range, but the Magdalena tinamou is very rare (perhaps extinct), while the Colombian tinamou is endangered. In both cases the main problem is habitat destruction, but hunting is another issue. The IUCN lists this bird as Least Concern, with an occurrence range of 1,800,000 km2 (690,000 sq mi).

Worked examples

Example 1 — a first encounter with Red-legged tinamou

Start with the simplest possible case. Write down what Red-legged tinamou 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 Red-legged tinamou 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 Red-legged tinamou 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 Red-legged tinamou

In research: Red-legged tinamou 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 Red-legged tinamou 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: Red-legged tinamou is common in secondary-school and first-year university syllabi. It links to neighbouring topics Birds described in 1863, Birds of Brazil, Birds of Colombia, so understanding it makes those chapters shorter.
In everyday life: Look for Red-legged tinamou 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.
