Question

Why the animals that lives in burrows usually wander during night time only?

Answer 1

As mostly there are no dangerous animal romping around in the night time.

Answer 2

During  the  day  the  land  may  get  too  heated.So    some   animals  prefer  to  shelter  themselves  in  burrows dug  deep  in  the  land.When  the  temperature  cools  down  they  come   out.This  happens  during  night  time. Also, some  animals  are  nocturnal . So  they  have  no  problem  in  hunting  during  night.Some  snakes  are  really  good  hunters  of   the  night.In  the  dark  instead  of  their  sight  their  pit  organs  do  the  work.It's  like  they  have  absolute  no  need  of  light  at  all.They  strike  with  pin  point  accuracy  even  in  total   darkness . Some  predators  which  lives  in  burrows  come  out  to  hunt  prey  at  night  because  not  every  animal  is  nocturnal.It's  an  adaptive  feature  which  is  well  visible  in  the   deserts.There  are  many  biological  reasons  why  animals  do  it.
