“Key West radar had a busy night, but not because of weather! The most impressive display of migratory birds so far this year occurred overnight Sunday," National Weather Service officials said in a Facebook post,

The radar shows different colors that show the difference between the birds and the weather.

“This product distinguishes between biological targets (birds) shown in green/yellow and meteorological targets (showers and rain) depicted in darker blues. The birds first appear on radar as they depart from Cuba and emerge in the Florida Straits, disappearing below the radar towards dawn as they reach mainland Florida.” The NWS said.

The radar time-lapse imagery shows a span of 10.5 hours.
