THE WILSON BULLETIN— December, 1922 
very closely resembled that of a fledgling bird awaiting the 
arrival of a parent with food. 
Nest No. 2 was discovered when hardly finished on June 13. 
On the 16th it contained two eggs and on the 18th four eggs. 
Incubation had commenced on the 18th as I saw the male feeding 
the female on the nest several times. These eggs hatched on 
June 29, making the incubation period about eleven days. Only 
two of the eggs hatched, the other two remaining in the nest for 
some time. 
On June 30 the blind was erected and an attempt was made 
to use it the same day. The birds, however, proved so wild I 
gave it up and it was not until July 3 at 3 :30 p. m. that any- 
thing could be accomplished. In direct contrast with the other 
pair of warblers, the female at this nest was wild and nervous, 
the male feeding twenty-four times and the female ten during 
the three hours the nest was under observation. The male had 
fed eleven times before the female became enough reconciled to 
the blind to feed the young. During this time the young were 
fed thirty-four times, during which 26 green larvae, 11 small 
winged insects, 1 spider, and 7 unrecognized objects were fed 
to the young. As remarked in discussing the first yellow warbler 
nest the habit of carrying food in the tip of the bill was marked 
and made it comparatively easy to identify larvae. At both these 
nests there was a great abundance of small dipterous insects and 
small larvae within a few inches or feet. This may have had 
some influence on the quantity of food carried on each trip by the 
parent as I have noted other warblers Avith beaks fully loaded 
coming to the nest. At these nests there were few times when 
more than oiie insect was carried. 
The excreta at both nests was disposed of either by swallowing 
or carrying away and the nests were kept scrupulously clean. 
Kedstart {Setopl:aga rtiUcilla) 
On June 26, 1915, while camping on Mormons Ridge north of 
Marshalltown, Iowa, I discovered a redstart nest containing 
one egg. This was a dainty nest woven of grass, hair, and root- 
lets in a fork of a hazel bush about four feet from the ground. 
On each of the two succeeding days, June 27 and 28, an egg was 
laid and on the afternoon of the latter date incubation com- 
menced. I watched the nest for three hours on the afternoon of 
the 28th. During this period the male came once to feed the
