2nd large Bird kill in addition to other fish and bird kill

Another large bird kill reported, this time in Louisiana

This is the third mass kill site so far with two bird kills in the thousands and one fish kill in the thousands. If they were all bird kills I would say it could be the weather combined with large cell phone towers which might create unusual broadcast or lightning events in the air. However, the fish kill could only be a chemical reaction or an explosion in the water like dynamite or something that poisoned them, unless the fish kill was to cover up the bird kills by drawing attention away from them.
