In Cuba this is the commonest of the North-American migratory 

 Ducks, arriving about the beginning of September and leaving the 

 island again in April. In Jamaica Mr. March says he has never 

 seen the " Bluewings " earlier than November, and that they again 

 appear in full summer-plumage in March and April on their way to 

 the north. This species is likewise met with in the other Antilles, as 

 far down as Trinidad. 



On the continent, Q. discors has been traced down as far as 

 Veragua, as will be seen by our list of localities. In Guatemala, 

 Salvin found it common in winter, arriving in September and leaving 

 again in March and April. It is met with in the high and low 

 districts alike, chiefly on the lakes.
