Table 2.

Studies reporting metric measures of bird-window collisions.

	Kummer et al.²⁶	Bayne et al.²¹	Our study
Participants	381	1458	328
Collision_Ever	56.5%	50.5%	52.7%
Collision_Year	43.9%	39.0%	52.7%
Collision_Number	5.55^*	1.7	3.7
Fatality_Number	0.48^*	0.7	0.47

Collision_Ever: the probability that a bird has collided with a window at some point in the past; Collision_Year: the probability that a bird has collided with a window in a year; Collision_Number: average of number of birds collided in a year; and Fatality_Number: average of number of collisions that resulted in a fatality in one year.

^*Predicted values obtained by standardized carcass search data.
