The order Falconiformes is a group of about 290 species of birds that include the diurnal birds of prey. The Black-shouldered Kite ( Elanus axillaris) or Australian Black-shouldered Kite is a small raptor found in open habitat throughout Australia Chordates ( Phylum Chordata) are a group of Animals that includes the Vertebrates together with several closely related Invertebrates Birds ( class Aves) are bipedal endothermic ( Warm-blooded) Vertebrate animals that lay eggs. Richard Bowdler Sharpe ( 22 November 1847 - 25 December 1909) was an English Zoologist. Year 1874 ( MDCCCLXXIV) was a Common year starting on Thursday (link will display the full calendar of the Gregorian calendar (or a Common The Accipitridae is one of the two major families within the order Falconiformes (the diurnal birds of prey) The Osprey (Pandion haliaetus, also called Sea Hawk, is a diurnal, fish-eating Bird of prey. The falcons and caracaras are around 60 Species of diurnal birds of prey that comprise the family Falconidae. The Secretary Bird, Sagittarius serpentarius, is a large mostly terrestrial Bird of prey. This article is about the taxonomic rank for the sequence of species in a taxonomic list see Taxonomic order In scientific classification used In Biology, a species is one of the basic units of Biological classification and a Taxonomic rank. Birds ( class Aves) are bipedal endothermic ( Warm-blooded) Vertebrate animals that lay eggs. Birds of prey are Birds that hunt for food primarily on the wing using their keen senses especially vision Raptor classification is difficult and the order is treated in several ways. Birds of prey are Birds that hunt for food primarily on the wing using their keen senses especially vision

Classification problems
Traditionally, all the raptors are grouped into 4 families in this single order. In Biological classification, family ( Latin However, in Europe, it has become common to split the order into two: the falcons and caracaras remain in the order Falconiformes (about 60 species in 4 groups), and the remaining 220-odd species (including the Accipitridae — eagles, hawks, and many others) are put in the separate order Accipitriformes. A falcon (fɔlkən or fælkən is any Species of raptor in the Genus Falco. Caracaras are birds of prey in the family Falconidae They are principally birds of South and Central America, just reaching the southern USA The Accipitridae is one of the two major families within the order Falconiformes (the diurnal birds of prey) Eagles are large birds of prey which are members of the Bird order Falconiformes and family Accipitridae, and belong to several genera The term hawk can be used in several ways In strict usage in Europe and Asia, to mean any of the Species in the Subfamily In a common way the raptors are classified the order Accipitriformes includes most of the diurnal Birds of prey: Hawks Eagles A prehistoric family known only from fossils are the Horusornithidae. The Horusornithidae are a Prehistoric family of Birds of prey.
The idea that Falconiformes should be divided into many orders is because of the suggestion that the order may not share a single lineage that is exclusive of other birds. The most controversial but also most well-supported suggestion is that Cathartidae are not Falconiformes but are related to the storks, in the separate order Ciconiiformes. Traditionally the order Ciconiiformes has included a variety of large long-legged wading birds with large bills Storks Herons Egrets However, morphological evidence supports the common ancestry of the Falconiformes, and the Strigiformes may be very close to the Falconiformes as well. The Owls are an order of birds of prey. Most are Solitary, and nocturnal, with some exceptions (e
The American Ornithologists' Union reintegrated the New World vultures (family Cathartidae) into Falconiformes in 2007. The New World vulture family Cathartidae contains seven Species found in warm and temperate areas of the Americas. This goes against the influential Sibley-Ahlquist taxonomy, in which all the raptors are placed into Ciconiiformes, but the Cathartids are considered to be outside the lineage that includes other raptors. The Sibley-Ahlquist taxonomy is a radical bird Taxonomy proposed by Charles Sibley and Jon Edward Ahlquist. While the latter is apparently correct, the "Ciconiiformes" sensu Sibley & Ahlquist are a paraphyletic, artificial assemblage and one of the weakest point of their classification scheme. In Phylogenetics, a group of organisms is said to be paraphyletic if the group contains its most recent common ancestor but does not contain all
Karyotype analysis indicates that New World vultures are indeed distinct, and the Accipitridae stand apart from all other falconiform birds insofar as that their microchromosomes show a high degree of merging to medium-sized chromosomes, which is quite unique in birds (de Boer 1975, Amaral & Jorge 2003, Federico et al. A karyotype is the characteristic Chromosome complement of a Eukaryote Species. A chromosome is an organized structure of DNA and Protein that is found in cells. 2005). Whether this has any bearing on the validity of the proposed Accipitriformes is still a matter of dispute, but it at least proves that the accipitrids are a monophyletic group. A clade is a taxonomic group comprising a single Common ancestor and all the descendants of that ancestor
Characteristics
Falconiformes are known from the Middle Eocene (the possibly basal genus Masillaraptor from the Messel Pit) and typically have a sharply hooked beak with a cere (soft mass) on the proximodorsal surface, housing the nostrils. The Eocene epoch (558 ± 02 - 339 ± 01 Ma) is a major division of the Geologic timescale and the second epoch of the Palaeogene period in The Messel Pit is a disused Quarry near the village of Messel, about 35 km southeast of Frankfurt am Main, Germany. Anatomy Stegosaurus --> Beaks can vary significantly in size and shape from species to species Their wings are long and fairly broad, suitable for soaring flight, with the outer 4–6 primaries emarginated.

Falconiformes have strong legs and feet with raptorial claws and an opposable hind claw. Birds of prey are Birds that hunt for food primarily on the wing using their keen senses especially vision A claw is a curved pointed appendage found at the end of a toe or finger in most Mammals, Birds, and some Reptiles. Almost all Falconiformes are carnivorous, hunting by sight during the day or at twilight. A carnivore (ˈkɑrnɪvɔər meaning 'meat eater' ( Latin carne meaning 'flesh' and vorare meaning 'to devour' is any animal with a diet consisting They are exceptionally long-lived, and most have low reproductive rates. Reproduction is the Biological process by which new individual Organisms are produced
The young have a long, very fast-growing fledgling stage, followed by 3–8 weeks of nest care after first flight, and 1 to 3 years as sexually immature adults. Sexual maturity is the age or stage when an Organism can reproduce. The sexes have conspicuously different sizes and sometimes a female will be more than twice as heavy the size of her mate. With falcons the male tends to be about a third smaller than the female, from which a male falcon is called a tiercel from the Old French word tierce = "third" from Latin tertius. A falcon (fɔlkən or fælkən is any Species of raptor in the Genus Falco. Sexual dimorphism is generally most extreme in specialized bird-eaters, like the Accipiter hawks, and borders on non-existent among the vultures. The genus Accipiter is a group of birds of prey in the family Accipitridae, mostly consisting of birds known as Goshawks and Sparrowhawks Vultures are scavenging Birds feeding mostly on the carcasses of dead Animals Vultures are found on every continent except Antarctica and Monogamy is the general rule, although an alternative mate is often selected if one dies. Monogamy is the custom or condition of having only one mate in a Relationship, thus forming a Couple.
Falconiformes are among the most diverse orders in size. The smallest species is believed to be the Black-thighed Falconet, small males of which can weigh only 28 g (1 oz), measure 14 cm (5. The Black-thighed Falconet ( Microhierax fringillarius) is one of the smallest birds of prey. 5 inches) and have a wingspan of 26 cm (10. 3 inches). The largest species is the Cinereous Vulture, at up to 14 kg (31 lbs), 118 cm (46 inches) and 3 m (10 feet) across the wings.
