WIGEON. Male. 
Some liiteresfcins featliers showiug curioiis colour and pattern changes. 
1. A normal flank feather from a youug male iu first plumage, September. 
•2, 3. Two flank first plumage feathers, November. These show a curious colour and pattern, change taking place just before 
their fall. Their place is taken by Termiculated feathers of the adult male. 
i, 5. When the big flush of the moult takes place in plumage of the young male in spring, all the new feathers that come in 
are not always similar to the adult. In backward birds some appear like these (uo. 4 from the mantle, no. 5 from 
the side of the lower neck). These feathers are, therefore, in direct sympathy with the old first plumage, and -will, 
according to the condition of the individual, soon change colour and pattern similar to fuhy adult feathers. 
6. A flank feather from the eclipse plumage of an adult male, October. This feather is about to fall, and shows weU the 
sympathy of colour and pattern for the new winter plumage. All the centre is still eclipse, but the outer edges are 
faintly similar to the winter. 
7, 8. New winter feathers from the flauk of an adult male, October. These have entered in an interesting half sympathy with 
the vanishing eclipse. The red brown iu the centre will presently disappear and give place to an extension "of the 
dark jagged bars across the feather. 
9. A flank feather from an adult male, October, coming in in complete form. 
Immature female in 
first plumage. Sept- 
ember 1st. 
2. Immature female, Nov- 
ember. In March 
there will be a flush 
of new adult feathers 
and the bird will he 
more or less mature.
