Septencoracias Morsensis
''Septencoracias'' is an extinct genus of bird related to modern rollers and other Coraciiformes such as kingfishers, bee-eaters, motmots, and todies. It contains one species, ''Septencoracias morsensis''. It was found in the Fur Formation of Denmark, dating back to the Ypresian of the Lower Eocene Epoch, about 54 million years ago. ''Septencoracias'' is one of the earliest known members of Coraciiformes, lending insight into the earliest radiation of this group. Description ''Septencoracias'' was a small bird the size of a Northern carmine bee-eater, ''Merops nubicus'', about 25 cm in length. It had a large skull in comparison to its body, about twice the length of the humerus. It is much larger than modern day rollers and its sister taxon ''Primobucco'', more similar in size and proportion to kingfishers, motmots, and bee-eaters. It had a stout, slightly curved beak, and the upper ridge of the beak curves gradually towards the tip of the bill like in living roller speci ...

Eocene
The Eocene ( ) Epoch is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope Carbon-13, 13C in the atmosphere was exceptionally low in comparison with the more common isotope Carbon-12, 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Popigai impact structure, Siberia and in what is now ...

Eocoracias
''Eocoracias'' is an extinct genus of bird related to modern rollers and other Coraciiformes such as kingfishers, bee-eaters, motmots, and todies. It contains one species, ''Eocoracias brachyptera'', and it lived approximately 47 million years ago (Lutetian The Lutetian is, in the geologic timescale, a stage or age in the Eocene. It spans the time between . The Lutetian is preceded by the Ypresian and is followed by the Bartonian.

Coracii
The Coraciiformes are a group of usually colourful birds including the kingfishers, the bee-eaters, the rollers, the motmots, and the todies. They generally have syndactyly, with three forward-pointing toes (and toes 3 & 4 fused at their base), though in many kingfishers one of these is missing. The members of this order are linked by their “slamming” behaviour, thrashing their prey onto surfaces to disarm or incapacitate them. This is largely an Old World order, with the representation in the New World limited to the dozen or so species of todies and motmots, and a mere handful of the more than a hundred species of kingfishers. The name Coraciiformes means "raven-like". Specifically, it comes from the Latin language "corax", meaning "raven" and Latin "forma", meaning "form", which is the standard ending for bird orders. Systematics This order has been seen to be something of a mixed assortment, and the Coraciiformes may be considered as including only the rollers. A ...

Harpactes
''Harpactes'' is a genus of birds in the family Trogonidae found in forests in South and Southeast Asia, extending into southernmost China. They are strongly sexually dimorphic, with females generally being duller than males. Their back is brownish, the tail is partially white (best visible from below), and males of most species have red underparts. They feed on arthropods, small lizards and fruit. Two species, cinnamon-rumped and scarlet-rumped trogons, were previously classified in a separate genus, ''Duvaucelius'', and a 2010 study found that these two were closely related and formed a separate clade from all of the other ''Harpactes'' trogons (except orange-breasted trogon, which forms a third group), but recommended that all three groups should be treated as congeneric. This same study also found that the genus '' Apalharpactes'', containing two species sometimes included in ''Harpactes'', is actually distantly related and thus a valid genus.

Colius
''Colius'' is a genus of mousebirds in the family Coliidae. The four species are widely distributed in Africa. Two other African mousebirds are placed in the genus ''Urocolius''. The genus ''Colius'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the white-backed mousebird (''Colius colius'') as the type species. The genus contains the following four species: A fossil species, ''Colius hendeyi'', was described from Early Pliocene remains found at Langebaanweg in South Africa. Some Miocene taxa from France were previously assigned to ''Colius''. Of these, only the Middle Miocene ''"Colius" palustris'' might plausibly belong there,Mlíkovský (2002) but it is more often separated in ''Necrornis''. In younger lineages like Passeriformes, extant genera (e.g. '' Menura'' and ''Orthonyx'') were around by then, though it must be remembered that simply because two taxa are of same taxonomic rank they do not need to be of the same age. All that can be sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tyto
''Tyto'' is a genus of birds consisting of true barn owls, grass owls and masked owls that collectively make up all the species within the subfamily Tytoninae of the barn owl family, Tytonidae. Taxonomy The genus ''Tyto'' was introduced in 1828 by the Swedish naturalist Gustaf Johan Billberg with the western barn owl as the type species. The name is from the Ancient Greek ''tutō'' meaning "owl". The barn owl (''Tyto alba'') was formerly considered to have a global distribution with around 28 subspecies. In the list of birds maintained by Frank Gill, Pamela Rasmussen and David Donsker on behalf of the International Ornithological Committee (IOC) the barn owl is now split into four species: the western barn owl (''Tyto alba'') (10 subspecies), the American barn owl (''Tyto furcata'') (12 subspecies), the eastern barn owl (''Tyto javanica'') (7 subspecies) and the Andaman masked owl (''Tyto deroepstorffi''). This arrangement is followed here. Some support for this split was provide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Afroaves
Afroaves is a clade of birds, consisting of the kingfishers and kin (Coraciiformes), woodpeckers and kin (Piciformes), hornbills and kin (Bucerotiformes), trogons (Trogoniformes), cuckoo roller ( Leptosomiformes), mousebirds ( Coliiformes), owls ( Strigiformes), raptors (Accipitriformes) and New World vultures (Cathartiformes). The most basal clades are predatory, suggesting the last common ancestor of Afroaves was also a predatory bird. The following cladogram of Afroaves relationships is based on Jarvis ''et al'' (2014), with some clade names after Yury, T. ''et al.'' (2013) and Kimball ''et al.'' (2013).Kimball, R.T. ''et al.''

Coracias
''Coracias'' is a genus of the rollers, an Old World family of near passerine birds related to the kingfishers and bee-eaters. They share the colourful appearance of those groups, blues and browns predominating. The two outer front toes are connected, but not the inner one. Taxonomy The genus ''Coracias'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his '' Systema Naturae''. The genus name is from Ancient Greek ''korakías'' (), derived from ''korax'' (, ‘raven, crow’). Aristotle described the ''coracias'' as a bird as big as a crow with a red beak, which some believe to be the chough. The type species was designated as the European roller (''Coracias garrulus'') by George Robert Gray in 1855. The phylogenetic relationships among the species were determined in a molecular study published in 2018. Species Nine species are recognized: Former species Formerly, some authorities also considered the following species (or subspeci ...
