VOL VI.] NESTLING-CUCKOOS. 333 



19 and 20. Found when fully feathered in Hedge-Sparrows' 

 nests. Both left the nests safely betM-een July 5th 

 and 8th. 



21. Found killed when about 14 days old in a Hedge -Sparrow's 

 nest. 



22. Found dead when about 11 days old near a Linnet's nest 



on July 6th. 



Of these, numbers 18, 19, and 20 were found and 

 watched by one of the boys of Felsted School. Numbers 

 21 and 22 I did not trouble about, as I found them dead. 



In addition to those above recorded I saw about six 

 young Cuckoos wliich had left nests not kept under 

 observation by me. 



The total number of young observed in the nest in 

 1912 was twenty- two. Of these eleven came to untimely 

 ends, which gives exactly the same percentage of loss 

 during the nestling-period as in 1911, viz. fifty per cent. 

 During the two years thirty-four young were found, of 

 which seventeen failed to leave the nest alive.
