Coo

The male [ring dove] will continue nest-coos for 3–4 days until his female partner begins to nest-coo. At that point the male's nest-coo begins to become less frequent[…].

An infant has only cries and coos with which to communicate distress and well-being. Adults have many more ways of expressing themselves. However, their expressions of disease and ease can be boiled down to sophisticated cries and coos. A call for help in whatever form is a cry. A sense of well-being however expressed is a coo. Healing in the context of cries and coos can be viewed as the process of resolving the cries and fostering the coos.

No birds, except as birds of paſſage, flew, / No bee was known to hum, no dove to coo.

DUET—MAYOR and MAUD. […] Like a Dove I'll coo and bill, pretty Maud, / I will not coo and bill, Mr. Mayor.

But oh! ſhall I, Misfortune's bondman, ſpeak / Of pleaſures and delights, where ſorrows ſhriek! / Can plaintive nightingale, or turte-dove, / When vultures tear them, ſing or coo of love?

The black-bird and the speckled thrush / Good-morrow gave from brake and brush; / In answer cooed the cushat dove, / Her notes of peace, and rest, and love.

Then did her soft breath stop and she lay still, her eyes yet open and smiling at the blossoms and the doves who sat upon the window-ledge and lowly cooed and cooed.
