By the fifth day earthworms are given the nestlings 
after being broken into small mouthfuls, and, as the days 
go by, these worms as well as large insects are given 
whole. The young Robins are voracious eaters, each one 
consuming, one authority says, sixty-seven earthworms 
daily. Certain it is that they double in weight every 
twenty-four hours at first, and at the end of sixteen 
days are nearly as heavy as the adults. Usually the 
eighteenth day witnesses their first flight, but it is a 
long time after that before they learn to forage for 
themselves. 
All efforts to find a “ Robin Roost” in California, such 
as is common among the Eastern species, have failed and 
I can obtain no definite information on this subject. It 
may be this is one of the habits abandoned with their 
entrance into the Land of Perpetual Summer.
