The two sexes of this bird were first brought to the notice of Ornithologists in 1845, 
by the late Baron de Lafresuaye in a paper published in the “ Revue Zoologique,” in which 
he names them both as separate and distinct species, calling the male bird Microjpogon 
Bourcieri , and the female C. Hartlaubi. This error remained undetected until the present 
year when it was discovered by Mr. Osbert Salvin, and recorded by him in a recent paper 
in the “ Ibis,” where, in a critique upon Mr. Lawrence’s list of the birds of Costa Rica, 
draws attention to the fact in the following words : — 
“ It has long struck me as singular that these two supposed species should always be 
“ found together. Upon examination of all the specimens that had the sexes marked, I 
“ found that all the C. Bourcieri were males, and all the C. Hartlaubi females. In a small 
“ collection from Ecuador obtained from Mr. Gould, I found a specimen with the head tinged 
“ with golden yellow, just as in C. Hartlaubi , while the forehead and throat as well as a few 
“ feathers on the sides of the occiput were red. In fact, this specimen, a young male, was 
“ shot while it was putting off the Hartlaubi , and assuming the male or Bourcieri plumage ; 
“ this transitional state convinced me that the sexes of one species had hitherto been 
“ regarded as distinct.’’
