With the view, however, of exciting more gene- 

 ral investigation into this subject, and of bringing 

 together as many species as have been known to 

 undergo this change, I subjoin a small list of such 

 female birds as have, in advanced life, assumed the 

 plumage of the male, with the names of those au- 

 thors who have noticed the fact.
