- 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.

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 · Those slow moving signals are likely to be insects, which travel with the wind. Using radar to track the movements of birds, bats and insects isn’t new—researchers realized...
With spring soon arriving and preparations for migration underway, here is a primer on what we do. We turn weather radar data into information on the numbers and flight directions of birds aloft in order to expand the understanding of migratory bird movement.
It’s the first concrete proof that radar can detect flying birds, but the idea is not immediately embraced: “At one meeting,” Lack later writes, “after the physicists had again gravely explained that clouds of ions must be responsible, Varley with equal gravity accepted their view, provided that the ions were wrapped in feathers.”

May 27, 2015 · Once you start thinking about it, La Pluma explained, it’s no surprise that radar works for tracking migrating flocks. “These things pick up droplets of water in the atmosphere,” and compared to that, “birds are gigantic targets.”. La Puma, now the director of the Cape May observatory, says there are some limitations.

Apr 21, 2022 · Within 20 minutes of lighting up, up to 16,000 birds crammed themselves into a half-kilometer radius. But when the lights flicked off, the dense clouds of birds on the radar screen dissipated just as fast, a finding later confirmed by on-site thermal cameras.
