40 SECRETS OF ANIMAL LIFE 



round Ben Lui, we heard the irrepressible dissyllabic 

 and trisyllabic call, "Cuck-oo" and " Cuck- 

 cuck-oo." One fellow seemed to call thirteen times 

 in succession, unless an echo or a rival falsified our 

 counting ; and every now and then we heard the

 playing its well-known trick. Or was it in line 

 with that mobbing of a cuckoo by a crowd of little
