INTRODUCTION

HHMI Tangled Bank Studios. (2024, February 19). Episode 17: Birds on the Brink [Video]. Wild Hope. https://www.wildhope.tv/episode/birds-on-the-brink/.

Hawai’i was once home to over 50 species of honeycreepers. Now, only 17 remain. This video describes the role of honeycreepers within the local ecosystem, causes of extinction, and Wolbachia-mediated efforts to curb the spread of avian malaria.

This Video Club engages students through guided questions, the use of graphic illustrations, and a current events research activity.

GUIDED QUESTIONS

BEFORE THE VIDEO

Match the following terms with their definitions.

Adaptation Native species Selective pressure
Ecosystem Parasite Vector
Invasive species Speciation  
  1. ______________________: A community of interacting organisms and their physical environment.
  2. ______________________: The process by which new species form.
  3. ______________________: An inherited characteristic that helps an organism survive and/or reproduce in a certain environment.
  4. ______________________: An environmental factor that influences the survival and reproduction of organisms. It can lead to changes in the traits of a population over time.
  5. ______________________: An organism that naturally occurs in a specific region or ecosystem.
  6. ______________________: An organism that is not indigenous, or native, to a specific area and whose introduction causes (or is likely to cause) economic or environmental harm, or harm to human, animal or plant health.
  7. ______________________: An organism that lives in or on another organism at the expense of the host.
  8. ______________________: An organism that transmits a disease, or disease-causing agent, from one host to another.

WATCH the Wild Hope video and discuss the following questions with your class.

INTRO

  1. How might the loss of honeycreepers impact the Hawaiian ecosystem?

 

EVOLUTION OF HONEYCREEPERS

  1. Name three types of adaptations among honeycreeper species.
  2. Highlighting one adaptation above, how might a selective pressure have led to its evolution in honeycreepers?

 

EXTINCTIONS

  1. Name three factors that have contributed to the endangerment of the Hawaiian honeycreeper.
  2. Why were mongooses introduced to Hawai’i and how did their introduction impact bird species?
  3. Why might high speciation make birds less resilient in the face of stressors like land loss and the introduction of invasive species?

 

RESTORATION

  1. How does restoring native trees help to save endangered birds?

 

REINTRODUCTION

  1. How do scientists know which species used to live on a particular island?

 

AVIAN MALARIA

  1. What is avian malaria and how is it spread?

 

MOSQUITO CONTROL

  1. How might releasing male mosquitoes with a different strain of Wolbachia help to control the spread of avian malaria?
  2. Which mosquitoes bite and spread disease, male or female?

 

CONCLUSION

  1. Would you support the release of Wolbachia-mosquitoes? Why or why not?

GRAPHIC ILLUSTRATION

Create a graphic illustration to accompany this video.

Graphic illustrations capture the interest of readers and concisely summarize a key finding of the research. They often accompany journal publications and news releases to highlight main take-home messages.

Create an illustration for one of the following topics:

#1 – EVOLUTION OF HAWAIIAN HONEYCREEPERS

The video discusses the origin and evolution of Hawaiian honeycreepers. Provide a summary illustration and/or highlight a specific adaptation.

#2 – EXTINCTION OF HAWAIIAN HONECREEPERS

The video discusses several contributing factors to the disappearance of Hawaii’s honeycreepers. Illustrate a summary of the factors or detail a specific cause.

#3 – WOLBACHIA-MEDIATED MOSQUITO MANAGEMENT

Create an illustrated overview of Wolbachia-mediated mosquito control.
