I was at Lake Apopka driving around watching the wildlife when I spotted these two.
The osprey was calmly eating his fish when the grackle flew over and sat on the branch opposite him.
They stared at each other for a while, then the grackle started calling out.
The osprey answered with his screech, which I think was telling the grackle that he wasn't getting the fish.
They continued on this way for a good 5-10 minutes, until the grackle turned his back on the osprey.
The osprey then continued eating the fish while the grackle continued to "talk".
