more  of  them  are  to  be  seen,  having  at  this  time,  in  quest
of  sustenance,  proceeded  probably  to  the  southern  ex-
tremity of  the  United  States.  Those  observed  in  tropi-
cal America,  may  be  hibernal  wanderers  from  the  cooler
parts  of  Mexico.  At  all  events,  they  select  the  milder
climates  of  the  Union,  in  which  to  pass  the  breeding
season,  as  at  this  time  they  are  but  rarely  seen  in  the
Southern  States,  Kentucky  being  about  the  boundary  of
their  summer  residence.
