Species on the move, Spring 2020: mid-March

Spring migration is well underway for a number of species, and the tables below highlight species you can expect in your regions over the coming week! Note that, as our 1-, 2-, and 3- day forecasts highlight, the most noticeable movements will occur in the southern and southeastern US ahead of an approaching weather system crossing the country’s mid-section (areas forecast to receive precipitation of various types appear in greens and blues in the image below).
