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.

 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.
