the childless deer
sings no more
akiramete ko no nai shika wa nakinu nari
by Issa, 1821
In other words, the deer doesn't bother with a mating call. This haiku, composed in the Ninth Month of 1821, seems to refer to Issa's own frustration as a would-be parent. His first three children by this point in time had all died.
naki ko wo omou koi mo wasure te
remember the children passed away
