Bottoms up! One of the Black-bellied Whistling Duck ducklings dabbling for treats on the bottom of the flats.
All ducks dabble, head down in search of food on the bottom.
Usually they just pop down, get a mouthful of stuff from the bottom and pop back up.
But Black-bellied Whistling Ducks stay down longer. Long enough that I sometimes worry that the ducklings may not know when to quit.
Then pop, they are back on the surface again.
