Stan’s Notes: A member of the blackbird family. Closely related to meadowlarks. A common bird of prairies, grasslands and open fields. In spring, the male will perch on plant stems and repeat its bubbling “bob-o-link” song (which provided the common name). Gives a loud, repeated “ink” whistle during flight. When disturbed, the female will run from her highly concealed ground nest before taking flight. By late summer, the males will have molted to a drab color similar to the females.
