he was quite active; and on the ninth he left the nest; though 
he was preceded by the other young birds. 
THE YOUNG YELLOW-THROATS 
On the third day (7. e., on July 12) it was noticed that the 
young Yellow-throats uttered a faint twitter on the approach of 
the parents; this was stronger and more musical by the fifth 
day (July 14). On the 16th it was recorded that ‘‘Red stood 
up in the nest and scolded when the Cowbird was fed.’’ Early 
in the feeding period we felt that these birds might not be 
getting enough food, but as the days went by their gain was 
noted. By the 16th they were well able to compete with their 
larger companion as the above shows. 
On the 17th the foliage above had been parted for some time 
to allow the sunlight to reach the nest in order that pictures 
might be taken.. The young birds did not like the heat of the 
sun, and would work over to the edge of the nest in search for 
shade. No doubt their departure from the nest was somewhat 
premature on account of this. At any rate at 9:01 a. mM. Red 
got on the edge of the nest, and after a moment’s hesitation, he 
hopped to a stick about six inches away. As soon as the mother 
bird returned to the nest, she seemed to urge him to venture 
farther on his journey. 
In the meantime some excitement caused among the birds by 
the appearance of a chipmunk, at which time Blue left the 
nest in much the same manner. Both birds, when they left the 
nest, were fairly well feathered out on the wings and back; 
and the breast was covered with a golden down. In July 20 
ene of the small birds was seen; and on the 27th the mother 
bird was seen in the vicinity with food in her beak.
