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.)
Sep 24, 2014 · The radio waves sent out by doppler radar bounce off raindrops and birds alike and return a signal to the receiver, writes Hannah Waters on her Scientific American blog.
Sep 24, 2014 · A radar loop would actually show the circular pattern becoming larger with time before dissipating as the birds fly up and outward. NWS meteorologist Michael Gorse told me by email that these...

Should you use a radar to track a storm?
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.

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.
May 8, 2009 · Caveats. Birds are not the only targets that radar detects. Precipitation appears as blocky, unevenly distributed patterns, very different from birds. But other biological targets like bats and insects appear in the same stippling pattern as birds, which makes distinguishing birds from bats, insects, and other aerial plankton challenging.
