account for its apparent absence from many places where it 
should breed. It is another of the swamp loving hirds, nest- 
ing in the trees and bushes which grow in the swamps or in 
wet places. 
Migration dates are lacking. It is likely that it winters 
in some favorable places in the state. Observers should be 
on the lookout for it.

All three of the North American cranes have been found 
in Ohio, one of them having wandered from the west. In 
general appearance the cranes show a marked resemblance 
to the herons, but the space in front of the eye is covered 
with bristles instead of being bare. While migrating they 
fly in long files. They are not such strict marsh haunters 
as the herons, but frequent uplands also. They are omnivo- 
rous feeders, often swallowing indigestible matter and dis- 
gorging it after a time. Frogs, lizards, snakes, field-mice 
and probably insects, and vegetable food are eaten with 
equal relish apparently.

The reports of the occurrence of this bird come from the 
western half of the state, where it appears to be a rare mi- 
grant. 
I find no dates of migration. Judging from the migrations 
in Iowa at nearly the same latitude, they should be seen 
passing northward in a long thin line during the last week 
in March and the first week in April.
