After August 1, all birds started to gain in weight. This is 
best illustrated by the changes in weight of eight repeats presented 
in Table . 3

*x July weight gain probably due to growth rather than accumulation of 
fat 
It will be seen. by Table that with the exception of the male 
caught July 3 and weighing only 117 grams, juvenals gain little weight 
in July. The indication is that most juvenals have attained mature 
growth by the time they take part in evening flights. The weight gain 
of the birds caught in August probably parallels a similar gain in 
adults due to fat accumulation rather than growth.
