I believe you about the white spot (that they are birds) and the black spot (that they are fish), but this big black shadow on the water instills some fear in my bones.
Say it's your shadow.
I have to sleep now, if I fall asleep and you don't confirm that it's your shadow, I'm afraid of what kind of horror movie I can dream up 😂
Ahahahaha... That is my shadow on the left, but that mud (white spot) is a trail of a fish that escaped from the camera... 😝
