Sounds
More often heard than seen, this bittern has a call that resembles a congested pump.
Feeding & Behavior
Usually solitary, it walks stealthily among cattails or bullrushes. If it senses that it has been seen, the American Bittern becomes motionless, with its bill pointed upward, causing it to blend into the reeds. It is most active at dusk. Feeds on amphibians, fish, insects and reptiles.
Habitat & Nesting
Marshes and shallow ponds, wet meadows.
Range
This bittern winters in the southern United States and Central America. It summers throughout Canada and much of the United States. As a long-distance migrant, it has a occurred as a very rare vagrant in Europe, including Great Britain and Ireland.
