  3. 3. Symmetry Of Birds: <ul><li>Birds have bilateral symmetry. If you cut a bird in half, something that is not normally practiced, you will get two mirror shape halves. (9) </li></ul>
  4. 4. Birds’ Phylum : <ul><li>Chordata Phylum – consists of mammals, reptiles, birds, bony fishes, and others </li></ul><ul><li>Dinosaurs – the common ancestors of birds and reptiles </li></ul><ul><li>Amniotes – mammals, birds, and reptiles </li></ul><ul><li>Last common ancestor of birds and mammals – Carboniferous period (360-300 MYA) </li></ul><ul><li>(2) </li></ul>
  5. 5. Birds’ Phylum:
  6. 6. Derived Characteristics: <ul><li>Most characteristics are flying adaptations: (1, 9) </li></ul><ul><li>The presence of wings and feathers. </li></ul><ul><li>Four – chambered heart = fast metabolism. </li></ul><ul><li>Fast metabolism = more energy for flying. </li></ul><ul><li>Bigger brains = Excellent visual perceptions. </li></ul><ul><li>Lighter hollow bones = better flying skills. </li></ul>
  7. 7. Derived Characteristics: Haliaeetus leucocephalus – Also known as the great Bald Eagle.
  8. 8. Birds’ Migration: <ul><li>A distinct characteristic of many birds is that most of them migrate during colder periods. Before migration, many birds increase their body fats, and actually DECREASE some of their organs. For navigation, birds use different “tools”, such as internal clock, sun position, star constellations, and some species’ ability to sense the Earth’s magnetic fields. </li></ul><ul><li>(9) </li></ul>
  9. 9. Differences From Mammals: <ul><li>The sex (gender) of birds is determined by Z and W chromosomes, rather than X and Y, as it is in mammals. (9) </li></ul><ul><li>Male Birds – ZZ chromosomes. </li></ul><ul><li>Female Birds – ZW chromosomes. </li></ul>Male Sparrow ( Passer eminibey ) Female Sparrow ( Passer eminibey )
  10. 10. Evolution Theory: <ul><li>Some theorists believe that birds came from… dinosaurs !!! Most paleontologists see birds as the only clade to survive the extinction. Feathers were also present in some dinosaurs. (9) </li></ul>Velociraptor – Velociraptor mongoliensis
  11. 11. !!! Feathers !!! <ul><li>Feathers’ functions: </li></ul><ul><li>Flights </li></ul><ul><li>Thermoregulation </li></ul><ul><li>Signaling </li></ul><ul><li>Camouflage </li></ul><ul><li>Distinguishing between themselves (species) </li></ul>
  12. 12. Bald Eagle ( Haliaeetus leucocephalus ) <ul><li>Commonly known as the U.S.A. symbol. </li></ul><ul><li>North America – near large bodies of water. </li></ul><ul><li>Hunt fish, birds, reptiles, small mammals. </li></ul><ul><li>Egg is cared for by both parents for 35 days. </li></ul><ul><li>Eagles reach maturity in about 4 – 5 years. </li></ul><ul><li>When breeding they lay between 1 – 3 eggs. </li></ul><ul><li>(4) </li></ul>
  13. 13. Bald Eagle ( Haliaeetus leucocephalus )
  14. 14. House Sparrow ( Passer domesticus ) <ul><li>The most widely spread birds in the world. </li></ul><ul><li>Found in urban areas, nest on urban buildings. </li></ul><ul><li>Ecological niche is cavity – nesting birds. </li></ul><ul><li>They move around by flying / walking (jump). </li></ul><ul><li>Feed on grains, seeds, and small insects. </li></ul><ul><li>Their eggs hatch in 2 – 3, maturity in one year. </li></ul><ul><li>These birds mate for life, 3 “babies” per year. </li></ul><ul><li>(5, 8) </li></ul>
