Although the American birds are slightly larger than those from the Old World, we 
see no valid reason for supposing that the Night-Herons of the two hemispheres are 
specifically different. American ornithologists recognize only one species of Nycticorax 
throughout the whole of the Neotropical Region, whereas Dr. Bowdler Sharpe believes 
that there are three well-characterized races, two of which are found in South America, 
from Peru to the Straits of Magellan and the Falkland Islands,$
