Inquiry Project 1 Inquiry Project 1 Presentation Transcript

  • Hummingbirds Kalena Gries Educ 373 Sept. 21, 2009
  • My Experience
    • Every summer my mom and I hang a hummingbird feeder filled with sugar water on our front porch. We have seen one to three hummingbirds on our feeder every summer. There seemed to be no pattern to their appearance so it was always a game to us to see who could spot one first. I was never able to take a picture of the hummingbirds because they quickly flew off at the slightest movement or sound.
  • My Hummingbird Feeder
  • Questions That Arose From the Experience
    • What kind of hummingbird was I seeing?
    • Do hummingbirds migrate? If so, where to?
    • Do hummingbirds tend to “summer” in the same place? (I wonder if we are seeing the same birds every summer or different ones.)
    • How do hummingbirds eat? How often do they eat? What do they eat besides sugar water? Why are they attracted to red?
    • What defense strategies do humming birds use when they are frightened or threatened?
  • Connection to the Standards
    • 4.4.3 – Observe and describe that organisms interact with one another in various ways, such as providing food, pollination, and seed dispersal.
    • 4.4.9 – Explain that food provides energy and materials for growth and repair of body parts. Recognize that vitamins and minerals, present in small amounts in foods, are essential to keep everything working well.
    • 6.4.3 – Describe some of the great variety of body plans and internal structures animals and plants have that contribute to their being able to make or find food and reproduce.
    • 6.4.8 – Explain that in all environment, such as freshwater, marine, forest, desert, grassland, mountain, and others, organisms with similar needs may compete with one another for resources, including food, space, water, air, and shelter. Note that in any environment, the growth and survival of organisms depend on the physical conditions.
    • 6.4.9 – Recognize and explain that two types of organisms may interact in a competitive or cooperative relationship, such as producer/consumer, predator/prey, or parasite/host.
  • Which Hummingbird?
    • Although I was not able to take pictures of my hummingbird visitors, I noticed that they all had greenish bodies with a white and red chest.
    • Based on this description and the fact that “only one kind [of hummingbird] lives in the eastern part of the United States and Canada” (p. 7), I have found that my visitors are Ruby-throated hummingbirds.

  • Ruby-throated Hummingbirds
  • Migration
    • Most hummingbirds live near the equator where there is adequate food year-round so they do not need to migrate. The hummingbirds that live in the U.S., however, must migrate south for the winter. Ruby-throated hummingbirds spend their winters in Central America.
    • “ Hummingbirds will come back year after year to the same garden” (p. 22). “They fly right back to the tree where they were born” (p. 29). This means there is a good chance that I am seeing the same hummingbirds and/or their offspring every summer.

  • Lunch Time!
    • Hummingbirds have long, narrow beaks and absorbent tongues. The end of their tongues has tiny bristles that sweep up any insects while lapping up the nectar.
    • Because their fast little bodies use up their energy so quickly, hummingbirds must eat every 15-20 minutes. “The hummingbird feeds most often in the early morning and late afternoon. It is important for it to eat as much as possible at sunset so that it can store enough energy to pass the night without eating” (p. 12).
    • In addition to sugar water (nectar), they eat the tiny insects that they find in flowers when looking for nectar. Nectar provides hummingbirds with quick energy, and the insects provide the necessary protein, minerals, vitamins, and fats.
    • Hummingbirds are attracted to red because red flowers usually have the biggest supplies of nectar. They are so attracted to the color that they will inspect any red object for nectar.

  • Defending Their Territory
    • Hummingbirds actively defend their territory through several self-defense tactics. They may puff themselves up to appear bigger and shake their heads back and forth or sing a song warning other hummingbirds to stay away from their food source. Some will use their bills to poke the enemy’s eyes out or use their sharp claws to pull feathers out. Often hummingbirds will use their speed to chase and attack their enemies, no matter the enemy’s size.
    • If the enemy is a person, they are likely to dive-bomb the person until he or she goes away.
  • Other Information
    • “ Its wings are so powerful that there is no need for the hummingbird to walk. For this reason, its legs are very small and weak and almost useless for anything except perching. Even if the bird must move only one inch, it will probably fly” (p. 9).
    • “ Hummingbirds are the only birds that can hover […] and back up in mid-air” (p. 19).
    • A hummingbird’s average resting heart rate is 500 beats per minute, and their wings flap about 75 times every second.
    • The average lifespan of a hummingbird is 3-4 years.
