 familiar and shewy little bird,  has attracted the attention of the natives to such a  
 degree as to have obtained a specific  appellation,—a distinction which  is seldom  
 conferred  by them on birds  of so  small a size.  It winters  towards  the tropics,  
 and arrives in Pennsylvania about the beginning of May, where some pairs remain  
 to breed, while  others advance  to the  north  as  fast  as the progress of summer  
 prepares  the  country  for  their reception.  It  reaches  the  banks  of  the  Saskatchewan  
 about  the  third week  in May,  and the  borders of Great Bear Lake,  
 in  the  sixty-fifth  parallel,  in  the  beginning  of June,  soon  after  the  snow  has  
 disappeared, but before the rivers  break  up.  It  retreats,  with its  young brood,  
 from the fur-countries in the beginning of September,  and from Pennsylvania  by  
 the middle  of that  month.  It is commonly seen in the low thickets which spring  
 up where  the trees  have  been cut  down in  the  neighbourhood of the fur posts,  
 and  is very active,  flying  continually  from  bush to  bush,  and  destroying  great  
 numbers  of the caterpillars which  harbour  on willows.  Its  notes  are  soft  and  
 pleasing, though without compass or variety.  It builds its nest near the ground,  
 in a  bush  or  in the  fork  of a low  tree,  of grass,  very compactly  woven,  and  
 lined with  hair  and down.  Its  eggs,  five in  number,  are of a greenish-white  
 colour, with  crowded  blotches of dark umber-brown at the thick end,  mixed with  
 a few subdued spots of purplish-grey.  The length of an egg is 1* inch. 
 DESCRIPTION 
 Of a male, killed on the banks of the Saskatchewan, May 25, 1827. 
 C olour  of the  dorsal  aspect intermediate between sulphur-yellow and olive-green.  Quill  
 feathers and  greater  coverts  umber-brown,  edged  with  sulphur-yellow.  The outer vanes of  
 the tail feathers and the tips of their  inner vanes  brown,  the  rest  of  the  inner  vanes  gam-  
 boge-yellow,  except  those  of  the  middle  pair of feathers, which are almost entirely brown.  
 Under  surface.  The  forehead, whole under  plumage,  and  inner wing  coverts, rich  king’s-  
 yellow,  approaching  to  saffron.  Breast  and  belly  streaked  longitudinally  with  brownish-  
 orange.  Legs yellowish-brown. 
 Form, &c., need not be detailed, as it is typical. 
 Thq female (killed on the 7th of June)  has  more  of the  olive  tint  on  the  dorsal  aspect,  
 very little  of the  bright-yellow  on  the  forehead,  and  the  colour  of the  under  plumage  is  
 pure  king’s-yellow,  without  orange  streaks.  A  young  bird,  from  Pennsylvania,  in  Mr.  
 Swainson’s  museum,  agrees  in  colour  with  the  female,  except  that  it  is  a  little  paler  
 beneath.
