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.
BirdCast applies weather surveillance radar to gather information on the numbers, flight directions, speeds and altitudes of birds aloft in order to expand the understanding of migratory bird movement. In this article, we’ll give you a brief overview and a behind-the-scenes look at the ways we apply radar data to study bird migration.
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.
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.

Sep 24, 2014 · Using radar to track the movements of birds, bats and insects isn’t new—researchers realized that animals were visible on radar during World War II—but the Internet now gives interested lay...
