Human Bias
Study Design
Fun Facts
100

These errors can lead to bias in human searches for bat and avian mortality. 

What is variation in monitoring methods and distance detection rates? 

100

This study design was used by researchers in combination with scent dogs.

What is transects oriented perpendicular to the wind?

100

These characteristics were important for selecting detection dogs.

What  is their health, athleticism, keenness to play with toys, and willingness to work with human handlers?

200

This is a recommended component to add search fatality studies to remove bias. 

What is searching to a maximum radius, utilizing tighter spaced transects, detection dogs? 

200

These are two proposed methods to define a maximum search radius. 

What is ballistics or pattern of spatial distribution? 

200

This was the time of year chosen by the author to conduct their research. 

What is through fall migration, September through November?

300

This causes human searcher rates to decrease?

small carcass size

300

Researchers used this to create an index of carcass visibility?

What is measured distances to trial carcass occlusions?

300

This is where the least amount of bird fatalities are found within the radius of wind turbines.

What is upwind of turbines?

400

Researchers can use these methods to amend the error of falsely determined removals of carcasses. 


What is taking fatality photos, keeping record of where/when remains found? 

400

This underestimates the fatalities found in a carcass survey. 

What is a smaller maximum search radius? 

500

This describes the accuracy and precision of the human searchers results. 

What is high accuracy and low precision? 

500

This model was used to fit the collective number of fatalities found at wind turbine sites.

What is logistic model?
