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.)
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.
Sep 24, 2014 · First, birds typically show up as those growing concentric circles. Also, the time of day is important. Many species of migrating birds take off in the evening, fly through the first part of the ...

Apr 21, 2022 · If the observers report too many birds circling aimlessly in the beams, organizers flip off the lights. In recent years, on-site observers have also used a complementary tool to quantify the orbiting birds: weather radar, which bounces off birds as well as raindrops.

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.
Feb 24, 2023 · Published February 23, 2023 8:49pm EST. How weather radar is tracking birds' migratory patterns. Due to the sensitivity of doppler radar, birds can easily be detected and show up on displays. Small birds are usually visible until they fly above or below radar beams.
