Bob and Mobirders -
Here is an interesting chunk of nesting behavior
regarding Great-tailed Grackles:
Here in Missouri, including Joplin, they are found
in cattail lagoons. 
As you go southwest of here they nest in trees in
parks and campuses well away from lagoons.
I would imagine "Joplin's" grackles are back.
I'll check tomorrow or Monday.
