by regurgitation (see Foreword) at intervals averaging 

 every half-hour throughout the day, the periods being 

 longer from 8 to 10 a.m. and 12 to 3 p.m., but now 

 fresh food is given them. The young Wrens feather more 

 slowly than some young birds, and usually remain in the 

 nest until sixteen days old ; one brood could neither be 

 coaxed nor starved into flying until the twenty-first day. 

 The location of the nest seems to affect the time of their 

 departure, and, in cases where it is high up, with no near

 some time after leaving home they are fed by both adults, 

 and sometimes return to the nest at night either alone 

 or with the mother bird.
