THE SENEGAL SEN-BIRD. 
different appearance than what is seen upon another 
change; this is what suggested the name of “ Protee” 
to Le Vaillant, who considers that this species and 
some others thus display themselves during the time 
of courtship as an attraction to the other sex. This 
beautiful plumage ceases with the season of incu- 
bation, and the male assumes nearly that of the fe- 
male, which is of a uniform wood-brown tinted with 
yellow on the belly and vent ; the bill and legs arc 
in this sex brown, while in the opposite they retain 
at all seasons their deep black colour. In an inter- 
mediate state of plumage the upper parts are of a 
reddish brown, and the lower parts of a yellowish 
wood-brown, having the splendid feathers of the 
throat and breast appearing among it ; on the belly 
and vent the feathers have the centres darker, giving 
a streaked appearance to those parts. In none of 
the conditions of plumage have we any trace of the 
axillary tufts seen in the two last birds. Caffraria 
and Senegal are the localities generally assigned to 
this species, our own specimens were received from 
the vicinity of Sierra Leone, while Le Vaillant states 
that it is found on several parts of both the east 
and west coasts.
