Insectivore radar figure

Caption

This figure shows the dispersal of hundreds of thousands of swallows and martins from the shores of Lake Erie and Lake Saint Clair, as captured by radar. The three roosts highlighted in black boxes were observed every year from 2000 to 2020. Higher values of reflectivity (measured in dBZ) indicate higher density of birds.
