This is the second night in a row that this return pattern has shown up in the same place. It could be waterfowl or something else. The color of the return seems to indicate that the numbers of birds moving might not be large. I saw the same image last night but hesitated to post because I've just never looked for migration this early in the spring but from posts on line it does sound like things are beginning to move around.
If you got to the National Weather Service and click on the button for a looping view of the national map, you can see the rings in the lower plains enlarging over time.
This is really going to help make my case of spring fever even worse!

You might find this an even better indicater. Real time relative velocity loop from the local radar site:

I should have mentioned red targets are approaching the site and green are heading away.
keep looking up,

That's an interesting link Claude. It appears right now that everything on the radar is moving away from the land ad toward the water. I would think that would indicate a weather system and not birds. I've often wondered if a lot of the phenomenon seen on radar in the evenings isn't birds but rather the radar picking up thermal changes in the atmosphere as the sun sets.
Hmm that's interessting but honestly i have a hard time determining it... I'm wondering what others have to say....
