Least Bittern

 

Least Bitterns are very small herons. They have long legs and toes, daggerlike bills, and long necks that they often keep drawn in, giving a hunched appearance.

Least Bitterns hunt by standing motionless and watching the water. Sometimes they take on acrobatic contortions, gripping multiple reeds and hanging just inches over the surface of the water.

Least Bitterns live mostly in freshwater and brackish marshes with tall stands of cattails or other vegetation. Cornell All About Birds
