Least Bitterns

Least Bitterns, Ixobrychus exilis, are some of the smallest herons in the world. They are hard to spot because they don’t wade in shallow waters like most herons. Look for them on reeds and cattails at the water’s edge in a pond, fresh marsh, salt marsh, or in mangroves.

Long toes make it easy for these birds to maneuver through dense vegetation in search of food. While clinging to a reed or cattail, bitterns will open and close their wings to startleĀ prey then capture them on the surface of the water with their long bills. Least Bitterns love to dine on large insects such as dragonflies and small fish such as minnows. Frogs, tadpoles, small snakes are favorite snacks.

Males build hidden nests of sticks, vegetation, and grass on bent reeds. Both parents incubate
2-7 eggs for 17-20 days and share in feeding via regurgitation for up to 2 weeks.

These beautiful little herons have the perfect colors to make them hard to spot. Watch for movement in the dense marsh at the edge of the water. When you spot a Least Bittern, spend some time watching this bird’s acrobatic feats among the reeds.
