FLYCATCHER. 201 



The female has the head and all the upper parts olive-green, 

 paler than the male; throat and cheeks paler; beneath the body 

 pale yellow, with an olive tinge on the belly, and beneath the tail ; 

 but this sex has not the blue grey head, nor white across the throat, 

 as in the male. The young bird resembles the female, gaining the 

 dark head at the second moult, though at all times may be perceived 

 by blowing the feathers aside. 



This species is found in the interior of the Cape of Good Hope, 

 in the neighbourhood of the Bay of Blettenberg, or Lagoa, and 

 towards Le Poort; it builds in the forks, at the ends of the branches 

 of trees, the nest made of dry grass, covered with lichen, and dry 

 fibres within, but neither hair nor feathers ; the eggs four in number, 

 greenish grey, dotted with rufous ; the hen sits sixteen days. M. 

 Levaillant notices a singularity in the male, which is, a kind of fatty 

 protuberance on each side of the vent, in the shape of a small egg, 

 white, like a gland, and filled with oily matter, as on the rump ; 

 but whether this was a natural production, or a disease, M. L. was 

 not able to determine.
