PLATE 2 



Ventral view of heads of Branta canadensis minima, illustrating variation 

 in color patterns. The Museum numbers of the specimens shown, reading from 

 left to right, are as follows: upper row, 22038, 22014, 22076; lower row, 22035, 

 22042, 22033. 



Typical minima is supposed to be marked with a white collar at the base of 

 the black neck, and with a black line on the throat dividing the white cheek 

 patches, as shown in no. 22035. The specimens figured illustrate every possible 

 combination of these markings, demonstrating the impossibility of properly 

 diagnosing the subspecies on the basis of color or pattern.
