well to the present bird. The nests are the same characteristic structures, the only 
difference being one of size, and the eggs are deposited about the same time. The 
habit, mentioned elsewhere, of covering the eggs with a perfect screen of weeds seems 
to be every where a constant one with the eared grebe, and I have never found a nest 
in which the eggs could be seen without first uncovering them. 
Both parents share in the care of the young after birth, and, as in the case of the 
larger species, the young are carried about on their backs. The families are difficult 
to find at this season, as they rarely visit the open water, but keep sedulously within 
shelter of the tules, whence their shrill calls may be heard coming from all directions, 
an - ! yet not a bird, young or old, be seen, unless extreme care be taken in approach¬ 
ing them. 
The following is a description of the young : 
First stage .—Head above black; a faint yellowish white line begins at base of bill, 
divides on forehead, and passes over either eye to hind ueclc; the latter is also streaked 
with white. Body above blackish brown ; each down shaft tipp6d with ash ; sides 
washed with plumbeous. Under parts rosy white. 
As will be noticed, the young of this species differs sufficiently from the similar stage 
in any of the others as to be readily identifiable. 
PODILYMBUS LeS8. 
P. podicejis (L.). Pied-bill Grebe. 
Although not nearly so abundant as the eared grebe, the “dabchick” is yet abund¬ 
antly represented on the waters of this region in summer, and doubtless also to a greater 
or less extent as a resident species. The Pied-bill nests in the same localities as the 
eared grebe, and in the general particulars of habits the two agree closely. 
The young of the present bird have very decided markings about the head, broad 
white and dark lines being contrasted alternately. On the back of the head are sev¬ 
eral irregular patches of bright rufous.
