1998 March 6, Cecil Adams, “The Straight Dope”, in Chicago Reader:

1991 September 13, Ted Shen, “Composing Women”, in Chicago Reader:
Bohmes Liebeslied, for flute and piano, is arresting in its low-key broodiness; Bittersweet Music I, its piccolo a lonely bird in its nervous twitters, continued the despairing mood.
1911, Milo M. Hastings, The Dollar Hen:
When a hen shows signs of broodiness remove her to the sitting-room.
