GENUS AIX BOIE. 



Wood Duck, reduced.

Very common; " throughout the entire State " (A. H. Boies); I have it authentically 

 reported from Kent, Monroe, Washtenaw, St. Clair and Muskegon counties and Macki- 

 nac Island; "common at Iron Mountain" (E. E. Brewster); "Keweenaw Point" (Knee 

 land); summer resident; March, rarely Feb., to Nov.; ''once common but now rare in 

 Monroe Co." (Jerome Trombley): breeds abundantly; nests in the tops or hollows of 

 trees, hence called tree duck; eggs, dirty yellowish white; one of our handsomest ducks; 

 an excellent game bird; " the males sometimes feed in flocks during the breeding season " 

 (S. E. White). This beautiful bird is common on the Red Cedar, which passes by our 

 college campus, where I have often taken it from April to Oct. Unfortunately. these 

 birds, formerly so common, are being rapidly thinned by hunters.
