(Oidemia deglandi--Oidemia americana)
The scoters, or coots, as they are called on the Atlantic coast, are
all found on this coast southward to Mexico. Of these the white-winged
scoter (=Oidemia deglandi=) is the most common, being found in large
numbers on all the bays and inlets of the coast as far south as the
Magdalena bay, Lower California.
