The Society is indebted for this bird to Captain Philip Parker 

 King, R.N., F.R. & L.S., who first discovered the species, and

 season in their native countries, it is of course with hesitation 

 that we give the three foregoing species as distinct. A general 

 similarity in the disposition of their colours prevails throughout
