Q:Information: - Birds (Aves), also known as avian dinosaurs, are a group of endothermic vertebrates, characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a lightweight but strong skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. They rank as the class of tetrapods with the most living species, at approximately ten thousand, with more than half of these being passerines, sometimes known as perching birds or, less accurately, as songbirds. - The tyrant flycatchers (Tyrannidae) are a family of passerine birds which occur throughout North and South America. They are considered the largest family of birds, with more than 400 species. They are the most diverse avian family in every country in the Americas, except for the United States and Canada. As could be expected from a family this large, the members vary greatly in shape, patterns, size and colors. Some tyrant flycatchers superficially resemble the Old World flycatchers which they are named after but are not related to. They are members of suborder Tyranni (suboscines), which do not have the sophisticated vocal capabilities of most other songbirds. - Uromyias is a small group of small Andean , tyrant flycatchers known as tit - tyrants . They were formerly recognized based on syringial and plumage characters , including a flatter crest and a longer tail , but was included within Anairetes due to genetic analysis . Recent analyses suggested splitting into Uromyias again . The tit - tyrants are fairly small birds ( 11 -- 14 cm ) that get their common name from the tit family , due to their energetic tit - like dispositions and appearance , primarily in their crests . Tit - tyrants live in temperate or arid scrub habitats and are mainly found in the Andes mountains . It is one of only a few genera of small flycatchers that occur at such high altitudes . - Plumage ("feather") refers both to the layer of feathers that cover a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies, and may vary with age classes. Within species there can be different colour morphs. After reading the paragraphs above, we are interested in knowing the entity with which 'uromyias' exhibits the relationship of 'parent taxon'. Find the answer from the choices below. Choices: - bird - ostrich - tyrannidae
A:
tyrannidae
