Two pairs of Blue-winged Teal begin their day of hunting for food at dawn on a cold March morning.
Blue-winged Teal are dabbling ducks which means they poke their heads and upper body under water to reach food without submerging themselves. This behavior is exemplified by the male and female in the background.
These ducks paddle along and dabble for plant and animal life they pluck or filter from the muddy bottom of the marsh. It’s an all day job.
