There is a higher density in Florida and the east coast than in Texas and further north.
Cold weather in south Texas is slowing the central migration down!
But that said, I now have a dozen pair and saw my first SA yesterday.
Also today a starling was setting on one roof causing problems. Using 22 CB longs I popped him with a PM on each side. The PM's flew up then back and looked over the edge down at the dead starling. I could swear I heard them say thank you!
