40 DIVERS—COLD-WEATHER DIVERS. 
The first issue in the spring occurs when winter is 
relaxing its grip, and is commonly dispersed along 
both coasts, sometimes appearing in large numbers, 
but generally scattered; especially is this the case dur- 
ing the late issues. 
During the fall migration they appear more in the 
interior, following the large rivers and down the lakes 
and rivers to the Gulf of Mexico, but do not appear in 
flocks as they do coastwise. 
They like to drift inshore to feed in the bays and 
estuaries, on both deep and shallow lakes, especially 
the shallow ones surrounded by timber and buck- 
brush; they like mud flats near wide rivers, so fre- 
quently are found in the South. Amongst aquatic 
plants, every other year is a flower season with few 
bulbs, followed by a bulb year with few flowers; hence 
some years these ducks appear upon a few particular 
lakes, during others they are found scattered over a 
good many. 
They nest, like hooded mergansers and woodducks, 
in holes in trees; but often choose other sites in un- 
frequented places. Like the surf coots their flesh is 
fishy in the spring, but in the fall they are fair eating.
