Described by Mr. Pennant. Bill black, cere 

 yellow: head deep brown; back the same, tinged 

 with rust: hind part of the neck streaked with 

 white: the coverts of the wings dusky, edged with 

 dull white ; those on the ridge with orange : ends 

 of the primaries dusky; the other parts barred 

 with brown and white: breast and belly white, 

 marked with heart-shaped spots: thighs sulphur- 

 coloured, speckled with dusky: vent feathers white: 

 tip of the tail white; then succeeds a broad dusky 

 bar; the remaining part barred with brown, tawny, 

 and black: legs long, and very slender. This 

 species is of an elegant form, and is about the size 

 of the Ringtail. It inhabits the province of New 

 Yorky appearing at the approach of winter, and 

 retiring in the spring. Mr. Pennant observes that 

 the Northern Falcon of Mr. Latham seems to differ 

 from this only in age or sex. It is of a dark ci- 

 nereous brown above, and beneath ferruginous 

 brown, with interrupted white bars: the tail 

 marked by four brown bars, and tipped with 

 white.
