 Female black @-@ tailed jackrabbits do not prepare an elaborate nest . They give birth in shallow excavations called forms that are no more than a few centimeters deep . Females may line forms with hair prior to giving birth , but some drop litters in existing depressions on the ground with no further preparation . Young are born fully <unk> with eyes open , and are mobile within minutes of birth . Females do not protect or even stay with the young except during nursing . Ages of <unk> and dispersal are unclear since the young are well camouflaged and rarely observed in the field . Captive black @-@ tailed jackrabbits are fully <unk> by 8 weeks . The young stay together for at least a week after leaving the form .
