Presentation Transcript

  1. Monday, May 4th, 2015 Pg. 134 RTW: What is one interesting thing you learned about Mollusca? • Objective: • I will be prepared for the Marine EOC on 5/18. • Agenda: • Final Review • Avesneed to send me quiz for approval • Homework: • Fish Food Project

  2. Tuesday, May 5th, 2015 Pg. 134 RTW: Would you rather fight a 100 duck size horses or 1 horse size duck? • Objective: • I will be able to cite examples and explain the adaptations to the marine environment of the invertebrate phyla: Aves. • Agenda: • Aves Foldable • Aves group be ready to present tomorrow! • Fish & Sharks group send digital documents by today! • Homework: • Fish Food Project

  3. Chordata Foldable (Class Aves) • Examples: Marine and coastal birds: Pelicans, Albatross, Blue-footed booby, Sandpipers, Penguins. Bird orders end in the suffix –iformes Characteristics: Light weight bones Endothermic Three feather types: Down, Contour, Powder Most have a gland to convert salth2o to freshh2o Several species have webbed feet for swimming

  4. Chordata foldable (marine birds) • Diagram: • Reproduction: egg-laying, internal fertilization

  5. Marine Birds Class: Aves

  6. Characteristics • Depend on the ocean for survival • Lightweight bones • Return to land to breed. • Endothermic = create their own body heat • 3 Types of feathers: • 1- Down = small, fluffy, closest to skin, for warmth. • 2- Contour = larger, cover wings and body, for flight. • 3- Powder = Repel water, protect the down

  7. http://www.birds.cornell.edu/ • Online Bird Guide

  8. Bird Orders • Class Aves broken into 29 orders • All orders end in –iformes • Ex. Pelecaniformes- Pelicans (totipalmate swimmers) • Ex. Passeriformes- Songbirds

  9. Diving Pelagic Birds • Open-ocean birds, spend most of their lives at sea • Puffins, petrels, shearwaters, albatross • Migrate thousands of km each year

  10. Large nostrils located in short tubes on sides/top of bill • Spend most of life at sea • Come to land only to breed • Wandering Albatross-Largest wingspan of all living birds (nearly 12 feet)

  11. Wandering Albatross

  12. Wandering Albatross chick

  13. Shearwater

  14. Penguins • Can dive down 800 meters for food • Flightless, marine, pelagic, swimming and diving birds • The Emperor Penguin is the largest @ 4ft, 75lb

  15. Penguins • The most aquatic of all marine birds • 15 species (all are in the Southern Hemisphere) • No contour feather (can’t fly) • Thick layer of fat and dense down feathers • Excellent swimmers/divers • Eyes adapted for underwater vision • Both males and females take care of watching the egg and chicks

  16. Babies Adelie Penguins Emperor Penguins

  17. Rockhopper Penguin King Penguins

  18. Penguin

  19. Totipalmate Swimmers • All 4 toes are webbed • Pelicans, Gannets, Cormorants& Frigatebirds • Some breathe through their mouth (nasal openings are closed)

  20. American White Pelican

  21. Blue-footed Booby

  22. Long-legged Waders • Herons, Egrets, Ibises, Spoonbills, Storks & Vultures • Herons & Egrets have S shaped neck in flight

  23. Herons & Egrets have S shaped neck in flight

  24. Storks hold neck extended in flight

  25. Bird populations decreased because of plume hunters (1902-1903) • Fashionable for women to wear feathers in their hats • 4 birds=1 ounce ($32/oz)

  26. 1,608 packages of plumes in a commercial sales room in 1902 • Each package weighed 30 oz totaling 48,240 oz • Required the lives of 192,960 herons

  27. Flamingos • Pink plumage due to carotenoids obtained from food, cyanobacteria • Most unusual feature is the bent bill held upside down to feed

  28. At one time occurred naturally in the state of Florida • Nest made on a cone shaped pedestal of mud • Young swim day of hatching

  29. Flamingo

  30. Marsh birds • Crane, Coots & Moorhens • Losing more species of birds than any major order of birds • The Whooping Crane is the tallest American bird

  31. Whooping Crane & chick

  32. Sandhill Crane -More commonly seen

  33. Roseate Spoonbill

  34. Shorebirds • Much diversity • Divers, skimmers, waders • Lakes, coastal waters, beaches, meadows

  35. Shorebirds • Sandpiper – narrow, pointed bill • Snowy egret – long, flexible neck • Roseate Spoonbill • Sea ducks • Sea Gull - scavengers

  36. American Avocet

  37. Diurnal Birds of Prey • Hawks, Eagles, Kites & Ospreys • Have short, decurved hooked beaks • Excellent eyesight • Feed on birds, mammals, fish or reptiles

  38. Osprey

  39. Kingfishers • Large heads with spearlike bills • Dive straight into water for fish

  40. Belted Kingfisher

  41. Perching Birds • All the Songbirds • Ex. Cardinals, Jays, Wrens, Warblers, etc. • Includes Loggerhead Shrike & Florida Scrub Jay

  42. Feather Anatomy

  43. What is preening? • Definition: Preening is the process by which birds groom and care for their feathers. When a bird is preening, she uses her beak to pick through her feathers -- removing any debris, arranging feathers that are out of place, and distributing a special oil that is secreted from a gland at the base of the tail. This oil helps a bird's feathers stay healthy and shiny.

  44. Wednesday, May 6th, 2015 No RTW: Aves group be ready to present when the bell rings! • Objective: • I will be able to cite examples and explain the adaptations to the marine environment of the invertebrate phyla: Aves. • Agenda: • Aves Fish Food Presentation • Homework: • Fish Food Project

  45. Chordate Foldable (sharks and fish) • Examples: • Class Agnatha: jawless fish • Class Chondrichthyes : sharks, rays, skates • Class Osteichthyes (Actinopterygii): bony fish • Characteristics: • Gills for breathing (several shark species have to swim to breathe) • Chondrichthyes have cartilage instead of bone • Osteichthyes have bony skeletons and ray fins • Agnatha have no jaws but rows of teeth in a circular formation

  46. Chordate (sharks and fish) • Diagrams: Reproduction: Agnatha and Osteichthyes: spawning or internal fertilization. Lay eggs (some are tended to others are on their own) Chondrichthyes: internal fertilization - viviparous: live birth - ovoviviparous: egg stays in mom until hatched - oviparous: egg laying (mermaids purse)

  47. Thursday, May 7th, 2015 Pg. 132 RTW: What is one interesting fact about Aves? • Objective: • I will be able to cite examples and explain the adaptations to the marine environment of the invertebrate phyla: Fish & Sharks. • Agenda: • Fish & Sharks Foldable • Fish & Sharks group be ready to present tomorrow! • Homework: • Fish Food Project
