This is a resident species in Florida, where it is becoming rather rare in 
many localities where it was once common. It nests in the marshes, the 
eggs being pale greenish in color. I have found two nests of this species on 
the Banana River. Eggs are usually from eight to ten innumber, but I have 
heard of fourteen eggs being taken in a nest. The note resembles that of 
the Black Duck.
