  1. 1. Outline • Introduction • Classification of birds • General Characteristics of Birds • Eagle Birds (Introcution,classification,Features) • Falcon Birds (Introcution,classification,Features) • Vulture Birds (Introcution,classification,Features) Birds 2
  2. 2. Introduction • Birds belong to the class Aves, There are more than 11,000 bird species that have been identified and described today. • And is the largest class of terrestrial vertebrates. • Among living vertebrates, only birds and bats can fly. • Many species of birds are economically important as food for human consumption and raw material in manufacturing, with domesticated and undomesticated birds being important sources of eggs, meat, and feathers. Songbirds, parrots, and other species are popular as pets. Birds 3
  3. 3. Classification Kingdom: Animalia Phylum: Chordata Superclass: Gnathostomata Class: Aves (Birds) Infraclass : Palaeognathae (ratites and tinamou) Infraclass: Neognathae clade: Pangalloanserae (fowl) clade: Neoaves Birds 4
  4. 4. Characteristic of birds • Feathers • Wings • Beak/Bill • Internal fertilization • Oviparous • Lightweight skeleton • Molting • Reproduction (Monogamous or Polygamous) • The laying of hard-shelled eggs Birds 5
  5. 5. Characteristic of birds Feathers Feathers; Made of keratin Function • Form flight surfaces that provide lift and aid steering • Prevent excessive heat loss • Incubation • Courtship • Water proofing Birds 6
  6. 6. Characteristic of birds Feathers Birds 7
  7. 7. Characteristic of birds Wings A bird’s forelimbs are modified into a pair of wings. Feathers cover most of the surface area of the wing. Birds 8
  8. 8. Characteristic of birds Lightweight • Rigid skeleton. Many of the bones are thin-walled and hollow, making them lighter than the bones of nonflying animals. • Air sacs from the respiratory system penetrate some of the bones. Birds 9
  9. 9. Characteristic of birds Endothermic metabolism A bird’s rapid metabolism supplies the energy needed for flight. Birds maintain a high body temperature of 40–41°C. Unique respiratory system A rapid metabolism requires an abundant supply of oxygen, and birds have the most efficient respiratory system of any terrestrial vertebrates. Birds 10
  10. 10. Eagle The people have seen eagles as a symbol of beauty, bravery, courage, honour, pride, determination, and grace. Birds
  11. 11. Eagle • Eagle is the common name for many large birds of prey (of the family Accipitridae). • Most of the 60 species of eagle are from Eurasia and Africa. • Outside this area, just 14 species can be found—2 in North America, 9 in Central and South America, and 3 in Australia. Birds 12
  12. 12. Classification Kingdom: Animalia Phylum: Chordata Class: Aves Order: Accipitriformes Family: Accipitridae Birds 13
  13. 13. Characteristic of Eagle • Eagles are large, powerfully-built birds of prey, with heavy heads and beaks. • have very large hooked beaks for ripping flesh from their prey, strong, muscular legs, and powerful talons • Eagles' eyes are extremely powerful. whose eyes are more than two times larger than the human eye, has a visual acuity up to 8 times that of humans. • The female of all known species of eagles is larger than the male. Birds 14
  14. 14. Characteristic of Eagle • Eagles fly alone at high altitude, No other bird can go to the height of the eagle ( Eagles fly with eagles) . • Eagles have strong vision. They have the ability to focus on something up to five kilometers away. • Eagles do not eat dead things. They feed only on fresh prey. • Eagles love the storm.The eagle uses the storm's winds to lift it higher. • When an Eagle grows old, his feathers become weak and cannot take him as fast as he should. Birds 15
  15. 15. habitat: • The eagles are generally distributed in all types of habitats and nearly all parts of the world. Birds 16
  16. 16. Groups: • Eagles are often informally divided into four groups: • (1) Fish eagles : Sea eagles or fish eagles take fish as a large part of their diets, either fresh or as carrion. • (2) Booted eagles : Booted eagles or "true eagles" have feathered tarsi (lower legs). • (3) Snake eagles : Snake or serpent eagles are, as the name suggests, adapted to hunting reptiles. • (4) Harpy eagles : • Harpy eagles or "giant forest eagles" are large eagles that inhabit tropical forests. Birds 17
  17. 17. Vuluters Vultures are scavenging birds feed mostly on the carcasses of dead animals. Birds
  18. 18. Vuluters • Vultures are medium to large-sized scavenging birds. • They feed mostly on the carcasses of dead animals. • About 23 extant species. • Live predominantly in the tropics and subtropics Birds 20
  19. 19. Birds 21
  20. 20. New World Vulture • Belong to the family Cathartidae. • 7 species. • Mostly found in warm and temperate areas of the Americas • They are able to smell dead animals from great heights. • They have weak flat feet for grasping. Birds 22
  21. 21. Old World vultures • belong to the family Accipitridae. • 16 species • found in Africa, Asia, and Europe. • They find carcasses exclusively by sight. • They have strong feet. Birds 23
  22. 22. Feeding • Vultures are scavengers. • Vulture stomach acid is exceptionally corrosive (PH=1.0). • New World vultures often vomit when threatened or approached. • New World vultures also urinate straight down their legs. Birds 24
  23. 23. Falcon The fastest animal in the world Birds
  24. 24. Introduction to Falcon • The Falcon is one of the most specialize and unique birds, • It has many characteristics that make it different from other species of birds and even all other living things, • Today we will present some or most of these features and differences Birds 26
  25. 25. Falcon Birds 27
  26. 26. Characteristic of Falcon 1. Falcons are fast Really fast Peregrine falcons have been clocked at reaching speeds of 242 miles per hour while diving for prey, making them the fastest recorded animal ever. 2. Falcons mate for life. There's no playing around for these birds: Falcons devote themselves to one partner for their reproductive years. 3. They can see better than you. Scientists estimate that falcon vision is eight times better than humans'. This allows the birds to spot small prey from nearly two miles away, and then swoop down precisely to catch it. Birds 28
  27. 27. Characteristic of Falcon 4. Amazing falcon can keep trackof three moving objects at same time. 5. Falcons use their beaks as weapons. Unlike other birds that only use sharp talons on their feet kill prey, falcons also have a sharp tooth at the end of their beak that they can use to quickly sever necks. 6. The life span of falcon in the wild is up to 15_17 years. Birds 29
  28. 28. Characteristic of Falcon • 7.Biometrics include: the female gyrfalcon stands about 24 in (61 cm) • tall and the male about 22 in (56 cm) tall. The female has a wingspan ranging between 4-5 ft (1.2-1.5 m) and weighs 3-4 p (1.4-2 kg). • The male weighs 2-3 p (0.9-1.4 kg) Birds 30
  29. 29. Characteristic of Falcon 8. There are three colour phases of gyrfalcons: light, gray or dark, with the female having heavier gray markings. 9. long pointed wings of all falcons, but their wingtips do not extend beyond the end of the tail when perched. Birds 31
  30. 30. Characteristic of Falcon 10. The Peregine Falcon has "nosecones" that serve to slow down the air entering it's nose at high speed. The design of the SR-71 engines also incorporated similar features on the inlets (which also retracted!) Birds 32
