Key Insights

• 💥 Bird collisions with windows are more common than widely understood.
• 😎 Researchers are developing methods to test and identify bird-friendly patterns on glass.
• 💳 The tunnel system being used for testing has contributed to credit in the Green Building rating system.
• 🧑‍⚕️ Protecting birds is essential for our future and overall ecosystem health.
• 🐦 Increasing options for bird-friendly materials in construction can encourage architects to adopt bird-friendly designs.
• 🤌 Vertical lines on windows spaced 4 inches apart can deter most birds, while horizontal gaps of 4 inches can still pose a risk.
• 🐦 Materials that 90% of birds avoid have been identified through testing.

Questions & Answers

Q: How common are bird collisions with windows?

Bird collisions with windows are more common than most people realize. The fact that almost everyone has witnessed such an incident suggests that the problem is widespread.

Q: How are birds caught for testing?

Researchers in the Bronx use fine nets to catch birds along the Bronx River during migration. The catching process is gentle, ensuring the birds' safety.

Q: How do researchers test glass patterns?

The researchers set up a tunnel with two glass panels, one with a pattern and one plain. They observe and document which glass panel the birds choose to fly towards, simulating real-world scenarios.

Q: How can commercial construction become more bird-friendly?

By incorporating bird-friendly designs and materials, architects can help reduce bird collisions. Testing various materials and patterns can provide options for constructing bird-friendly buildings.

Summary & Key Takeaways

• Many people witness birds colliding with windows, but most are unaware of the extent of this issue.

• A team of researchers in the Bronx is conducting tests on glass patterns to understand how birds perceive and avoid them.

• The ultimate goal is to develop bird-friendly designs for commercial construction.
