NYC Window-Bird Collisions                                                                               

8th Grade Biology WebQuest

 

Rosalily Belandres-Rios

INTRODUCTION

Every year, thousands of migratory birds die after flying into reflective glass windows in NYC skyscrapers and buildings. Birds often mistake reflections of the sky, clouds, or trees for real habitat. Artificial lights at night can also disorient migrating birds and attract them toward dangerous buildings. Scientists estimate that between 90,000 and 230,000 birds die each year in New York City from window collisions. NYC Bird Window Collisions.mp4 Flaco's Final Flight Discussion Activity.pdf

TASK

Imagine you are part of a team of wildlife conservation scientists working for the New York City Bird Alliance. Your team has been asked to investigate a growing environmental problem in New York City: birds colliding with glass buildings and windows.

Your mission is to investigate the causes of bird collisions, analyze scientific evidence, evaluate current NYC policies, and design realistic solutions that could help save migratory birds.

Using Public Policy Analyst (PPA), students will:

     Explain why bird-window collisions occur.

     Analyze evidence related to bird collisions in NYC.

     Identify human activities that contribute to the problem.

     Evaluate bird-friendly building policies.

     Design and defend solutions to reduce bird collisions.

     Create a slide presentation.

PROCESS

Time frame - 5 class periods       Grouping - in groups of 4

STEP 1: Define the Problem

Research and define:

     bird-window collisions

     migratory birds

     reflective glass

     light pollution

Guiding Questions

1.  Why do birds collide with windows?

2.  Why is NYC especially dangerous for migratory birds?

3.  How do artificial lights affect bird migration?

4.  Why are migratory birds important to ecosystems?

 

STEP 2: Gather the Evidence

Gather and analyze evidence related to bird collisions in New York City.

Examine:

     bird collision statistics

     migration maps

     photographs of reflective buildings

     bird collision hotspot maps

Guiding Questions

1.  What trends do you notice in the data?

2.  Why are glass buildings dangerous to birds?

3.  How does light pollution affect migration?

4.  Why are collision numbers likely underestimated?

Suggested Resources

     NYC Bird Alliance – Project Safe Flight

     Audubon – Bird-Friendly Buildings

     NYC Bird Alliance – Lights Out Initiative 

 

STEP 3: Identify the Causes

Investigate the main causes of bird collisions.

Examples:

     reflective glass

     transparent windows

     artificial lighting

     skyscrapers

Guiding Questions

1.  Why can birds not recognize glass as a barrier?

2.  How do reflections confuse birds?

3.  Why are nighttime lights dangerous during migration?

4.  Which buildings are most dangerous to birds?

STEP 4: Evaluate Existing Policies

Research New York City’s bird-friendly building laws and conservation efforts.

Examples

     NYC bird-friendly building legislation

     Lights Out NYC

     Project Safe Flight

     bird-safe glass requirement

–Guiding Questions

1.  What is the purpose of the law or program?

2.  How effective has it been?

3.  What are its strengths and weaknesses?

4.  Should more buildings be required to follow these rules?

STEP 5: Develop Solutions

Work with your group to design solutions that reduce bird collisions.

Possible Solutions

     bird-safe glass/screen

     window decals/patterns

     reducing nighttime lighting

     automatic blinds

     green roof redesigns

     motion-sensitive lights

Requirements

Your solution must:

     reduce bird collisions

     be realistic

     explain environmental benefits

     identify possible limitations

 

STEP 6: Select the Best Solution

(Feasibility vs. Effectiveness)

Evaluate your group’s solutions using the chart below.

Discussion Questions

1.  Which solution would save the most birds?

2.  Which solution is most affordable?

3.  Which solution could NYC implement quickly?

4.  What trade-offs exist?

 

STEP 7: Presentation

As environmental scientists, your group will present your findings and proposed solution to the class as if you were presenting to the New York City Environmental Protection Board. Each group will be given 5–7 minutes. Every group member must participate.  Presentation Rubric.docx

Students may choose ONE of the following:

     Google Slides

     PowerPoint

     Canva presentation

Your group presentation must include:

  1. Title Slide
  2. The Problem
  3. The Causes of the Problem
  4. Evaluate Existing Policies
  5. Develop Solutions
  6. The Best Solution Proposed
  7. Conclusion, Reflection, Recommendation

After all groups have presented, the students will complete a reflection worksheet. Presentation Reflection Questions.docx

CONCLUSION

Congratulations, conservation scientists! Through this WebQuest, you investigated how urban environments can impact migratory birds and explored ways scientists, architects, lawmakers, and citizens can help reduce bird collisions in New York City.

 

Bird-window collisions are one of the most preventable causes of bird deaths. Small changes, such as turning off lights at night or using bird-safe glass, can save thousands of birds every year. Scientists and engineers continue working together to make cities safer for wildlife while still meeting human needs.

As future problem-solvers, you can help protect biodiversity and design communities that are safer for both humans and animals.
