They  breed  in  society,  in  holes  of  rocks  that  overhang  the  sea,  where  they  deposit  one  or  two  eggs.  The  young  are 
fed  with  oily  substances  which  the  parents  throw  off  their  stomachs.

Bill  as  long  as,  or  shorter  than,  the  head,  more  or  less  broad  at  the  base  (varying  in  the  sexes)  ;  the 
sides  more  or  less  compressed  towards  the  tip,  which  is  more  or  less  compressed,  much  elevated  and 
arched,  lengthened,  and  acute :  the  lower  mandible  shorter  than  the  upper,  with  the  tip  and  gonys  arched 
and  acute :  the  nostrils  tubular,  horny,  varying  in  length  from  one  fourth  to  nearly  two  thirds  of  the 
length  of  the  bill,  with  the  aperture  single,  frontal,  and  crescent-shaped.  Wings  long,  pointed,  with  the 
first  quill  the  longest.  Tail  moderate,  rounded  or  wedge-shaped.  Legs  with  the  apical  part  of  the 
thigh  hardly  naked.  Tarsi  shorter  than  the  middle  toe,  laterally  compressed,  and  covered  with  small 
scales.  Toes  long,  with  the  outer  as  long  as  the  middle  one,  the  inner  shortest,  and  all  united  by  a 
full  web;  the  lateral  toes  margined  exteriorly,  the  hind  toe  in  the  form  of  a  large  subtriangular 
claw. 
These  birds  live  in  the  higher  latitudes  of  both  hemispheres  during  the  summer,  and,  as  the  winter  approaches, 
migrate  in  numerous  flocks  to  the  more  temperate  seas.  They  are  rarely  seen  near  the  shores,  regardless  of  the 
heavy  sea  and  gales.  Their  flight  is  usually  rapid  and  continuous,  or  in  graceful  curves  near  the  surface  of  the  sea, 
seeking  fish,  the  blubber  of  whales,  and  other  marine  animals  on  which  they  prey  ;  and  the  large  species  has  been  noticed 
killing  small  petrels  and  young  gulls,  for  the  purpose  of  feeding  on  their  hearts  and  livers.  In  holes  that  overhang  the 
sea,  the  female  lays  one  very  large  egg.  The  young  are  fed  with  oily  substances,  which  the  parents  throw  off  from 
their  stomachs  for  that  purpose.
