it here within the past five years. This is only another example of the story 
being so often repeated in our land, of local extermination preceding the gen- 
eral extermination of our once common, beautiful birds. The wood-duck, un- 
like all others of its family, builds a feather-lined nest in the hollow of a 
partly decayed tree near the water and at quite a distance from the ground. 
From this nest the young are carried in the parent birds’ bills to the water’s 
edge. 
ORDER PYGOPODES: DIVING BIRDS. 
Pied-'billed Gre'he: Hell-diver. This common little fellow can dive at the 
flash of a gun and be beyond harm before the charge fired has reached its 
mark. 
In many ways its eastern name of ‘Mabchick” is most descriptive, for its nest 
resembles a mud pancake floating on a bed of rushes and covered, in the day 
time when the sun shines, with a layer of muck which is scraped off at night 
and the eggs incubated. 
The pied-billed grebe is a common summer resident in our marshes and 
ponds, and can generally be found with little difficulty.
