apparently not yet nesting. This is one of the latest breeding clucks in this 
vicinity. 
Plegadis guarauna. White-faced Glossy Ibis. In nearly every patch of tides 
was a nest or two of this species, and in the patch farthest west which covered 
about a half acre, there must have been at least two hundred nests. They were 
built on bent down tules, ancG'were composed of tide stalks and lined with marsh 
grass. They were situated from two to six feet above the water, the average height 
being about four feet. About half the nests examined contained young and most 
of the others held badly incubated eggs. A very few fresh sets were found but the 
height of the nesting season was past. The sets almost invariably consisted of 
three or four eggs. In one or two instances sets of two incubated eggs were noted, 
and three nests contained five eggs^each, two nests six eggs each, and one nest had 
seven. It is probable that set-Suiiumbering more than five eggs were deposited by

more than one bird. In fact they invariably showed two different types of eggs. 
The color of the eggs evidently fades with incubation, as the heavily incubated eggs 
are a much lighter blue than the freshly laid ones. This is probably the largest 
breeding colony of these birds in southern California west of the mountains. 
Botaurus lentiginosus. Bittern. Rather common but no nests were found. 
The pumping note of this bird w'as heard continualby both da\' and night. 
Ixobrychus exilis. Least Bittern. Rather common. Seven nests were found. 
These contained three sets of five eggs each, one set of which was hatching, one 
set of four, badly incubated, one set of three, slightly incubated, and one fresh egg. 
The nests were flimsy affairs, built of small tide stalks and marsh grass, and were 
placed in the tules from three to four feet above the water. In one case the nest 
was built on top of an old blackbird’s nest. In no case was the bird flushed from 
the immediate vicinity of the nest.
