Large numbers of birds are expected to migrate at night, so head outdoors to look and listen. The Bird Migration Forecast says it will be high through Thursday with over 3,000 birds per kilometer per night.
The BirdCast website says it forecasts three nights into the future with reasonable accuracy based on previously published research.
BirdCast uses weather surveillance radar to gather information on the numbers, flight directions, speeds and altitudes of birds in order to understand migratory bird movement, according to its website. Click here to learn more about radar data and bird migration.
