SUMMARY OF THE ACTIVITIES OF A KINGBIRD. 
Tyrannus tyrannus. 
The same nest, with two young, was under observation for a period of six 
days beginning with the morning on which the eggs hatched. The data of 
the first day were imperfectly recorded and are, therefore, not included in the 
summary. The data cover the 3rd, 4th, 6th, 7th, and 8th day after the hatch- 
ing of the eggs.
