very narrow transverse lines of black, only half as 
broad, in fact, as the bands on C. canorus ; the 
tarsi are only feathered half way down the back, and 
are not, as in canorus , clothed with feathers their 
whole length ; but the chief, or at least the most 
obvious, distinction between the two birds is in their 
tails. In our Senegal bird there is almost an equal 
mixture of black and white on the three external 
tail-feathers on each side, while the outermost is 
white, with a broad well defined bar near the tip, 
and five others, more oblique and irregular, which 
touch each other for a little space in the middle of 
the inner web. No such bands are seen in canorus. 
which has the outer tail-feather black tipt with 
white, and two rows of small white spots, one on the 
shaft, and another on the marginal edge only of the 
inner web ; the orbits and two-thirds of the lower 
mandible, in this , are orange-red, so also are the 
nostrils : but these characters are not seen in ca 
norus. 
The young of this species differs so materially in 
its plumage from the male, as to require a separate 
description. The size is rather less : the ground- 
colour of the upper plumage is something the same, 
but crossed all over with narrow and generally in- 
terrupted bands of whitish, more or less tinged with 
ferruginous or fawn colour ; these bands are broken 
into spots on the greater wing-covers, where they 
form about four series on the edge of the external 
web ; while others, still smaller, are in the same 
situation on the quill-feathers. On the under plu-
