BLACK BIRDS. 15 



NOTES TO 'BLACK BIRDS.' 



SCOTER. — This duck, although entirely black, is described 

 with the other ducks under ' DiViNG DucKS,' the fact that it is 

 a duck being as evident as tlie blackness of its plumage. 



SWIFT. — As this bird, because of its usually high and rapid 

 flight, is more likely to be recognised as ' Swallow-like ' in form 

 than as a bird of black plumage, it has been described under 

 'Swallow and Swallow-like Birds.'
