For the Birds Investigation

Which statement best explains a common cause of bird-window collisions?

• Birds see indoor plants as reachable habitat

• Birds smell food through sealed windows

• Birds hear echoes that mimic open air

• Birds detect heat patterns as safe paths

A city wants to cut nighttime bird collisions without major construction. Which approach aligns with bird-safe design and practical constraints like cost and reliability?

• Implement scheduled lights-out programs citywide

• Install mirrored glass on all buildings

• Increase indoor plant displays near windows

• Use brighter exterior lighting for visibility

According to the initial setup, which pair should be treated as constants when simulating the chickadee collision with a window using modeling clay?

• Room temperature and humidity

• Window material and angle

• Mass of model and drop height

• Bird species and wind speed

In the drop test simulation, which measurable outcome should be used as the dependent variable to assess bird mortality?

• Mass of the model bird

• Diameter of deformation

• Type of screen material

• Simulation drop height

In the model shown, which variable is intentionally changed during trials to test its effect on clay deformation?

• Mass of the clay ball

• Distance from screen to floor

• Tension of the screen in hoop

• Force used to drop the ball

Which action most directly improves reliability by reducing random error in a bird-window collision model experiment?

• Report only the trials that match predictions

• Use one trial with careful notes

• Increase the number of trials performed

• Change the model to a heavier bird

You are modeling birds striking a window by dropping a ball at a screen. To increase validity by reducing human error, which change is best?

• Switch to any available materials

• Use fewer trials but better notes

• Drop from slightly different heights

• Use a consistent release mechanism

Which reason best explains why using models and simulations is helpful when designing solutions to bird-window collisions?

• They guarantee real birds never collide again

• They collect data without harming birds

• They always cost more than field trials

• They eliminate the need for classroom testing

A prototype bird-protection screen was tested on a 500 cm² simulated window, while a typical household window is about 8000 cm². Which refinement best supports effectiveness when scaling up to full-size windows?

• Remove frames so birds can bounce off the glass

• Decrease frame strength to allow more screen give

• Add framing to reduce screen flex on larger spans

• Use the same thin screen without added supports

Which trade-off is most reasonable when implementing exterior screens to reduce bird mortality on buildings?

• Improved bird safety but increased cost and altered aesthetics

• No change in biodiversity with higher maintenance savings

• Lower cost but greater risk of bird injuries and deaths

• Better building views with unchanged bird collision rates
