Practice Reading: Fill in the Blanks (Dropdown) ID: #48156 Wolf Image
Instructions
The  image  of  a  wolf  silhouetted  against  the  night  sky  has  led  many  to  believe  that  wolves  howl  at  the  moon.  However,  scientific  investigation  into  the  behavior  of  these  canines  reveals  that  the  moon's  presence  has    to  do  with  their  iconic  vocalizations.  Wolves  use  howling  as  a  form  of  communication,  not  as  a  homage  to  the  celestial  body  above.  Howling  serves  several  critical    within  wolf  packs:  it  helps  members  keep  in  ,  allowing  them  to  locate  one  another  when  separated  by  large  distances.  It  also  serves  as  a  territorial  claim,  warning  other  packs  away  from  their  domain.  The    that  wolves  howl  at  the  moon  likely  stems  from  the  coincidental  timing  of  their  howls  with  the  moon's  visibility  in  the  night  sky.  Wolves  are  more  active  during  the  night,  which  is  also  when  the  moon  is  most  visible,  leading  to  the  association  between  the  two.  Additionally,  the  posture  a  wolf  adopts  when  howling    nose  pointed  upwards    further    the  myth.  In  reality,  wolves  point  their  muzzles  toward  the  sky  to  project  their  calls  as  far  as  possible,  not  because  they  are  directing  their  howls  at  the  moon.
