with their wings to attract our attention away from the nests. These demonstra- 
tions were, however, confined entirely to the Pied-bills, the Eared Grebes exhibit- 
ing little or no interest in their nests. 
By the third week in May the great majority of nests contained full comple- 
ments of eggs, and one set of eggs was hatching on May 18. During the early 
part of June sets of eggs and broods of newly hatcht young were equally abundant, 
and by June 20 a large majority of the eggs had hatcht. 
The freshly hatcht young were very pretty little fellows covered with black 
down, broadly streakt with whitish stripes running lengthwise of the head and 
body, giving them a somewhat sinuous appearance when in the water. They evi- 
dently take to the water as soon as hatcht, and are wonderfully active and quick.

A baby grebe half the size of a chick can swim as fast as a man can wade thru 
the water comfortably, and the distance they can swim under water at this tender 
age is surprizing. They hide very effectively by diving and coming up to the 
surface under tiny bits of floating moss or rubbish, where they lie perfectly still 
with only the tips of their tiny bills exposed above the water. Their feet are ab- 
normally large, which probably accounts for their remarkable swimming ability, 
and when quiet in the water the feet and head float on the surface, the rest of the 
body being submerged. The only note of the young grebe is very similar to the 
“cheep” of the domestic chick, first heard when the egg is pipt — very weak and 
tiny at first, but growing in strength and power as the bird becomes larger, until 
by the time the young are three-fourths grown the note is quite loud and clear.
