It’s true. Weather radar images show where radar beams have been “reflected” as they sweep the atmosphere. They’re useful for showing weather conditions because the beams are reflected by precipitation and the water vapor in clouds, but they can also be reflected by swarming masses of birds or insects.
Home. About. Weather Surveillance Radar and Bird Migration Primer. A 24-hour national mosaic animation of radar imagery featuring large numbers of birds taking flight. Circular blue and green features represent bird migration; precipitation appears as irregular bands. (Base reflectivity radar imagery from October 16th-17th, 2017, 12pm-12pm EST.)
Dec 23, 2018 · However, the range of this effect is <200 ft, so a weather radar can't be relied on to prevent bird strikes. It's also not well-studied and not verified across a wide range of species. The beam might also completely miss the birds due to scanning. So it's not a reliable bird deterrent.
