THE BOOK OF MIGRATORY BIRDS 147 



In the female the plumage is brownish-black, paler on 

 the under surface, on the auriculars a patch of greyish 

 white; the bill and legs have not the vivid colouring of 

 the male. 



The young much resemble the female during the first 

 year, the white spots on the head being apparent; the 

 feet beginning to show their brilliant colour.
