Red-knobbed Coot
The red-knobbed coot or crested coot, (''Fulica cristata''), is a member of the rail and crake bird family, the Rallidae. It is a resident breeder across much of Africa and in southernmost Spain on freshwater lakes and ponds. It builds a nest of dead reeds near the water's edge or more commonly afloat, laying about 7 eggs (or more in good conditions).Liversidge, Richard. “The birds around us: Birds of the Southern African region” Pub: Fontein 1991 Taxonomy The red-knobbed coot was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with all the other coots in the genus '' Fulica'' and coined the binomial name ''Fulica cristata''. Gmelin based his account on the earlier descriptions by the French naturalist Georges-Louis Leclerc, Comte de Buffon and the English ornithologist John Latham, neither of whom had included a binomial name. They gave the type locality ...

Eurasian Coot
The Eurasian coot (''Fulica atra''), also known as the common coot, or Australian coot, is a member of the rail and crake bird family, the Rallidae. It is found in Europe, Asia, Australia, New Zealand and parts of North Africa. It has a slaty-black body, a glossy black head and a white bill with a white frontal shield. The sexes are similar. Similar looking coot species are found throughout the world, with the largest variety of coot species living in South America. Taxonomy The Eurasian coot was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under its current binomial name ''Fulica atra''. Linnaeus specified the locality as Europe but this is now restricted to Sweden. The binomial name is from Latin: ''Fulica'' means "coot", and ''atra'' means "black". Four subspecies are recognised: * ''F. a. atra'' Linnaeus, 1758 – Europe and north Africa to Japan, India, southeast Asia, Philippines and Borneo * ''F. a. l ...

Little Crake
The little crake (''Zapornia parva'') is a very small waterbird of the family Rallidae. ''parva'' is Latin for "small". Its breeding habitat is reed beds in Europe, mainly in the east, and just into western Asia. This species is migratory, wintering in Africa. At in length, they are slightly smaller than the spotted crake, from which they are readily distinguished by the lack of dark barring and white spots on the flanks. The little crake has a short straight bill, yellow with a red base. They have green legs with long toes, and a short tail which is barred black and white underneath. Unlike other ''Porzana'' crakes, this species has strong sexual dimorphism: Adult males have mainly brown upperparts and blue-grey face and underparts. They resemble the sympatric Baillon's crake (''P. pusilla''), which has strongly barred flanks and is a little smaller. Females have buff underparts, and are grey only on the face; they are more similar to the yellow-breasted crake (''P. flaviven ...

Potamogeton
''Potamogeton'' is a genus of aquatic, mostly freshwater, plants of the family Potamogetonaceae. Most are known by the common name pondweed, although many unrelated plants may be called pondweed, such as Canadian pondweed (''Elodea canadensis''). The genus name means "river neighbor", originating from the Greek ''potamos'' (river) and ''geiton'' (neighbor). Morphology ''Potamogeton'' species range from large (stems of 6 m or more) to very small (less than 10 cm). Height is strongly influenced by environmental conditions, particularly water depth. All species are technically perennial, but some species disintegrate in autumn to a large number of asexually produced resting buds called turions, which serve both as a means of overwintering and dispersal. Turions may be borne on the rhizome, on the stem, or on stolons from the rhizome. Most species, however, persist by perennial creeping rhizomes. In some cases the turions are the only means to differentiate species. The leav ...

Precocial
In biology, altricial species are those in which the young are underdeveloped at the time of birth, but with the aid of their parents mature after birth. Precocial species are those in which the young are relatively mature and mobile from the moment of birth or hatching. Precocial species are normally nidifugous, meaning that they leave the nest shortly after birth or hatching. These categories form a continuum, without distinct gaps between them. Altriciality Etymology The word is derived from the Latin root ''alere'', meaning "to nurse, to rear, or to nourish" and indicates the need for young to be fed and taken care of for a long duration. By contrast, species whose young are immediately or quickly mobile are called ''precocial''. Precociality Etymology The word "precocial" is derived from the same root as ''precocious'', implying early maturity in both cases. Superprecociality Extremely precocial species are called "superprecocial". Examples are the megapode birds, which ...

Egyptian Geese
The Egyptian goose (''Alopochen aegyptiaca'') is a member of the duck, goose, and swan family Anatidae. It is native to Africa south of the Sahara and the Nile Valley. Egyptian geese were considered sacred by the Ancient Egyptians, and appeared in much of their artwork. Because of their popularity chiefly as an ornamental bird, escapees are common and feral populations have become established in Western Europe, the United States, and New Zealand. Taxonomy The Egyptian goose is believed to be most closely related to the shelducks (genus ''Tadorna'') and their relatives, and is placed with them in the subfamily Tadorninae. It is the only extant member of the genus ''Alopochen'', which also contains closely related prehistoric and recently extinct species. mtDNA cytochrome ''b'' sequence data suggest that the relationships of ''Alopochen'' to ''Tadorna'' need further investigation. Etymology The generic name ''Alopochen'' (literally, ''fox-goose'') is based on Greek (''alōpós ...

Flight Feather
Flight feathers (''Pennae volatus'') are the long, stiff, asymmetrically shaped, but symmetrically paired pennaceous feathers on the wings or tail of a bird; those on the wings are called remiges (), singular remex (), while those on the tail are called rectrices (), singular rectrix (). The primary function of the flight feathers is to aid in the generation of both thrust and lift (force), lift, thereby enabling bird flight, flight. The flight feathers of some birds have evolved to perform additional functions, generally associated with territorial displays, courtship rituals or feeding methods. In some species, these feathers have developed into long showy plumes used in visual courtship displays, while in others they create a sound during display flights. Tiny serrations on the leading edge of their remiges help owls to fly silently (and therefore hunt more successfully), while the extra-stiff rectrices of woodpeckers help them to brace against tree trunks as they hammer on ...

Frontal Shield
A frontal shield, also known as a facial shield or frontal plate, is a feature of the anatomy of several bird species. Located just above the upper mandible, and protruding along the forehead, it is composed of two main parts: a hard, proteinaceous callus and a soft, fleshy corium. It is thought to play roles in protection, mate identification, sexual selection, and territorial defense. Composition The callus is a hard, keratinous section of the frontal plate located highest on the forehead. It is generally more pigmented than the surrounding corium. Underneath the callus is a Malpighian layer of tissue that connects the structure to the maxilla. This layer is supplied with blood via vessel-containing dermal papillae. It has been observed to resemble the texture of calloused human skin. The corium is a thick, dense mass of connective tissue fibers that makes up the largest portion of the frontal plate. It contains layers of cells that aide in enlarging or flattening the structur ...
