Chronology of quail hatching on the Dale, Forbes, and Alma areas in 1964 was 
determined from two samples of juvenile quail. One sample consisted of 24 quail 
broods flushed during the summer months. Size, and plumage characteristics, were 
used to estimate the ages of these broods. The other sample consisted of 81 
individual quail captured by nightlighting in September and October; these juvenile 
quail were aged to the nearest week by the progress of the molt of the primary 
flight feathers. Surprisingly, all groups of these night-roosting quail contained 
juvenile birds of different ages. Age variations among these juveniles ranged 
from 6 to 16.5 weeks within the same group. The age composition of these night- 
roosting quail indicated that the groups were composed of chicks from different 
clutches, or, if they were from the same clutch, that the molt of primary feathers 
was highly variable. 
The chronology of hatching as determined from the brood sample indicates an 
earlier and more prolonged period of hatching than does that determined from the 
nightlighted sample (Table 3)-
