The true finches are small to medium-sized passerine birds in the family Fringillidae. Finches have stout conical bills adapted for eating seeds and nuts and often have colourful plumage. They occupy a great range of habitats where they are usually resident and do not migrate. They have a worldwide distribution except for Australia and the polar regions. The family Fringillidae contains more than two hundred species divided into fifty genera. It includes species known as Canaries, siskins, redpolls, serins, grosbeaks and euphonias.
A passerine is any bird of the order Passeriformes, which includes more than half of all bird species. Sometimes known as perching birds, passerines generally have an anisodactyl arrangement of their toes, which facilitates perching.
Charadriiformes is a diverse order of small to medium-large birds. It includes about 390 species and has members in all parts of the world. Most charadriiform birds live near water and eat invertebrates or other small animals; however, some are pelagic (seabirds), others frequent deserts, and a few are found in dense forest. Members of this group can also collectively be referred to as shorebirds.
The European robin, known simply as the robin or robin redbreast in Great Britain and Ireland, is a small insectivorous passerine bird that belongs to the chat subfamily of the Old World flycatcher family. It is found across Europe, east to Western Siberia and south to North Africa; it is sedentary in most of its range except the far north.
The Japanese robin is a small passerine bird in the family Muscicapidae. This species was formerly named Erithacus akahige, or Komadori. Its range extends from the south of the Kuril and Sakhalin Islands throughout Japan.
The Ryukyu robin is a bird endemic to the Ryūkyū Islands, of Japan. The Okinawa robin previously was considered a subspecies.
The rails, or Rallidae, are a large cosmopolitan family of small- to medium-sized, ground-living birds. The family exhibits considerable diversity and includes the crakes, coots, and gallinules. Many species are associated with wetlands, although the family is found in every terrestrial habitat except dry deserts, polar regions, and alpine areas above the snow line. Members of the Rallidae occur on every continent except Antarctica. Numerous island species are known. The most common rail habitats are marshland and dense forest. They are especially fond of dense vegetation.
The smew is a species of duck and is the only living member of the genus Mergellus. Mergellus is a diminutive of Mergus and albellus is from Latin albus "white". This genus is closely related to Mergus and is sometimes included in it, though it might be closer to the goldeneyes (Bucephala). The smew has hybridized with the common goldeneye.
The Siberian blue robin is a small passerine bird that was formerly classified as a member of the thrush family, Turdidae, but is now more generally considered to belong to the Old World flycatcher family, Muscicapidae. It and similar small European species are often called chats. Recent research suggests that this species and some other East Asian members of Luscinia should be classified in a new genus, together with the Japanese and Ryūkyū robins. The genus name Larvivora comes from the Neo-Latin larva meaning caterpillar and -vorus meaning eating, and cyane is Latin for "dark-blue".
Aythya is a genus of diving ducks. It has twelve described species. The name Aythya comes from the Ancient Greek word αυθυια, which may have referred to a sea-dwelling duck or an auklet.
The bird genus Hirundo is a group of passerines in the family Hirundinidae. The genus name is Latin for a swallow. These are the typical swallows, including the widespread barn swallow. Many of this group have blue backs, red on the face and sometimes the rump or nape, and whitish or rufous underparts. With fifteen species this genus is the largest in its family.
Lullula is the genus of woodlarks, songbirds in the family Alaudidae. There is only one remaining extant species, the woodlark which is found in Europe, the mountains of northern Africa, the Middle East and western Asia. The remainder are known only from the fossil record.
The Serravallian is, in the geologic timescale, an age or a stage in the middle Miocene Epoch/Series, which spans the time between 13.82 Ma and 11.63 Ma. The Serravallian follows the Langhian and is followed by the Tortonian.
Luscinia is a genus of smallish passerine birds, containing the nightingales and relatives. Formerly classed as members of the thrush family Turdidae, they are now considered to be Old World flycatchers (Muscicapidae) of the chat subfamily (Saxicolinae). The chats are a lineage of Old World flycatchers that has evolved convergently to thrushes.
Rallus is a genus of wetland birds of the rail family. Sometimes, the genera Lewinia and Gallirallus are included in it. Six of the species are found in the Americas, and the three species found in Eurasia, Africa and Madagascar are very closely related to each other, suggesting they are descended from a single invasion of a New World ancestor.
Aegithalos is a genus of passerine birds in the family Aegithalidae (bushtits), encompassing majority of the species in the family.
Hydrolagus is a genus of fish in the family Chimaeridae found in the Atlantic, Indian and Pacific Oceans.
The Chimaeridae, or short-nosed chimaeras, are a family of cartilaginous fish.
Larvivora is a genus of small passerine birds belonging to the Old World flycatcher family Muscicapidae that occur in central and eastern Asia.
The Okinawa robin is a passerine bird endemic to Okinawa of Japan. It previously was considered a subspecies of the Ryukyu robin.
