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.
Apr 21, 2022 · On weather radar, multispecies rivers of passing birds can be filtered out from rainclouds, allowing their large scale movements to be forecast like weather. (Meteorologists face the same problem—telling apart birds and storm systems—in reverse.)

Radar, an acronym for radio detection and ranging, was originally developed to detect enemy aircraft in World War II. As the decades have passed, it has become a valuable tool for studying all kinds of objects in the atmosphere. One of radar’s most common applications is the detection of meteorological events—especially thunderstorms, tornados, and...
Equipped with computing power and advanced radar technology, we can begin to provide detailed data on avian activity in the atmosphere
The BirdCast team, along with other radar ornithologists, uses a broad array of tools to make sense of a treasure trove of information collected by radars about birds, such as migration density, flight speed, and direction. Our data are not complete, though. Many advances in radar technology have aided in our abilities to differentiate birds from r...
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.
May 8, 2009 · During this ascent and during migratory flight, birds interact with pulses of energy emitted by the radar across the continental US. The pulses of energy scattering off of birds closer to the radar are lower in altitude, meaning that reflected energy will pass through and out of the layer of bird migration.
Sep 24, 2014 · Weather radar can tell you whether to pack an umbrella and poncho for the day, but, to ornithologists and others in the know, it also reveals the tell-tale signatures of migrating birds.
The New Migration Science. Fall migration will bring 4 billion birds into the skies over the United States. That’s not a guess—it’s hard data, gleaned from the first-ever national bird count using weather radar. Cornell Lab of Ornithology scientists analyzed data from 143 weather radar stations from 2013 to 2017 to provide the first large ...
