Migration Picks Up Behind Storm Front

With a large storm front moving ahead of cold air moving in from the north, radar is showing what appears to be significant movement in the Dakotas and Nebraska. Birds are probably taking advantage of the southward air flow. Movement ahead of the front is affected by the winds out of the south bringing in the warm, humid air that is causing these storms to fire up.

There should be new migrants showing up in yards Tuesday morning.

Warblers began showing up in Northfield on Tuesday afternoon.

You are seeing fall migrants and soon we will see out spring migrants here in Australia - but shorebirds. They also make us of the storm fronts. Bar-tailed Godwits fly directly from Alaska and make use of all the winds.
