In the light phase the three races, glupischa, rodgersii and 

 columba, seem to be nearly equally abundant. The dark birds, 

 which form, I think, about 65 per cent of the whole, swell the 

 ranks of glupischa and cohwiba considerably. If rodgersii has a 

 dark phase it is indistinguishable from that of glupischa.
