I just returned from outside in Madison, WI, where I was met by a swarm of flying insects… don’t ask me what they were, but I can tell you one thing: they’re all prospective bird food! Spring is springing all around today. Southerly flow from the Gulf Coast to the Great Lakes will mean migration tonight although the presence of a strong low pressure system will keep some birds grounded by heavy precipitation. It, therefore, remains to be seen how much of an influx we’ll get overnight. Moving to the east coast, southwest winds building into tonight will definitely convey some birds up into the Mid-Atlantic by morning.
