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 in number, but I have 

 heard of fourteen eggs being taken in a nest. The note resembles that of 

 the Black Duck.
