Subfamily ANSERINiE. Geese. 



Geese are gregarious, especially during migrations. When flying 

 the flock assumes a V-shaped form and is led (it is claimed) by an old 

 gander. They feed principally upon roots, seeds of aquatic plants, 

 and grain and are often found in the grain fields in large numbers. 

 The sexes are similar.
