DIVERS—COLD-WEATHER DIVERS. 39 
owing to its feeding range being in shallower water, it 
often misses it. The third issue soon scatters after its 
arrival and breeds through the United States. 
The feeding grounds are more inshore than those 
of the bluebills, and they feed more upon seeds such 
as frogbit, duck and pond weed, being very fond of 
the bulbs of the non-scented water lily, upon which 
they will gorge themselves and get exceedingly fat; 
at that time they are counted a delicacy for the table. 
The playgrounds are in open pieces of water sur- 
rounded by weeds and lily pads, in buck-brush, wil- 
lows and wild rice. The roosting grounds are in buck- 
brush, the edges of timber, down smartweed and flags. 
During the fall migration, the local birds form the 
first issue, and the second and third come down earlier 
than the bluebills; so that cold weather finds them 
rapidly approaching the frost line. Here is another 
example of a cold-weather bird, in the spring, moving 
southward before others who are warm-weather birds; 
as the pintail of the non-divers. They are both tim- 
ber and prairie birds, according to location. 
For food, see chart. 
Their clutch is twelve to sixteen white-colored eggs, 
often with a greenish cast. Length 18.00; wing 8.00:
