From: Radar quantifies migrant concentration and Dawn reorientation at a Great Lakes shoreline
Comparison of dawn, day, dusk, and night target passage rate (TPR) at paired shoreline and inland sites. This analysis includes data from trials A, B, and C on the east coast of Lake Michigan during spring of 2014. The diagonal dotted line in each figure represents the 1:1 ratio that would be expected if passage rates were the same at shoreline and inland locations. The black line is the Poisson least rectangles regression line, representing the estimated relationship between shoreline and inland passage rates. The shaded confidence region spans the bootstrapped 95% confidence intervals of slope and intercept. Each point represents the mean TPR for a single biological period. Note the difference in axis scales among biological periods
