82 THE BIRD GROWN UP 
Nestlings are never known to refuse anything 
to eat, and wren food seemed to suit the sparrows, 
for they soon outgrew the nursery. 
All summer this queer thing went on. The | 
sparrows reared three or four broods, and the 
wren did his full share of the work. And not 
only of feeding the young, but of repairing and 
rebuilding the nest for each fresh brood.
