A really cool phenomenon caught the attention of meteorologists in the Twin Cities around sunset on Tuesday.
Weather radars suddenly lit up with blue and green, yet there was no rain in the forecast.
That's because it wasn't rain, it was migrating birds.
The NWS shared the following gif showing the pattern of birds taking off from and passing through the Twin Cities area, heading south for the winter.
The NWS noted that these birds were mostly geese and ducks, with Minnesota's migration season shortly drawing to a close.
According to Birdwatcher's Digest, the last of the ducks move out of the state during November, as lakes begin to freeze over.
The Minnesota DNR's waterfowl report for Nov. 2 said there are still a lot of ducks, which in turn is making for good hunting.
Canadian goose numbers have been rising as well, though the DNR notes that "large numbers still remain in Southern Canada."
Tundra swans are also heading south at this time of year, typically mid-to-late November, as they gather along the Mississippi River before heading to wintering grounds in North Carolina and Virginia.
Ducks and geese will be among the first to return to the state after winter, with the Nature Conservancy noting that lakes around Worthington in southwestern Minnesota are awash with them when spring returns.
