This is something we have never seen before. Hubby saw a bare tree in the water with 3 common grackles on it. One flew out over the water & hovered 2 ft over the water, then dove in. Just its head went in & it sat on the water like a duck for 4-5 secs, then flew back to tree with a smelt in its beak. One of the other grackles chased it away with the smelt. Shortly the 3rd grackle flew by with a smelt in its beak, Sorry no pics, Going back there again today if weather holds out. Is this normal for grackles?
