A Series of Eggs of the Bobolink. 
In his Manual of North American Birds, page 
306, Mr. Eidgway falls into the strange error 
of stating that the Bobolink ( Dolichonyx ory- 
zivorus) lays from two to five eggs, whereas 
any number less than four would be an incom- 
plete set, and six and seven not unusual. 
Considering how very common the birds are 
it is astonishing how hard it is to find their 
eggs, and to this fact must be ascribed their 
comparative scarcity in collections. They 
vary greatly in color and markings.
