In some accounts she is seen combing her hair as she laments. She is heard more often than seen, wailing as she approaches the abode in the late evening or early morning, sometimes perching on the windowsill two to three hours or even days before a death. As she moves off into the darkness witnesses describe a fluttering sound, such as the sound made by birds flying at night. Hence, the mistaken belief that banshees manifest as birds such as the crow. The inaccurate association with crows is probably due to confusion of the banshee with the primitive Celtic goddess Badb, the goddess of war who appeared frequently in the form of a crow.
Banshees also wail around natural forms such as trees, rivers, and stones.
Although there have been reports of banshees accompanying Irish families who emigrated to the Americas, it appears the banshee more often grieves for an emigrant at the ancestral family seat in Ireland. Stories are told of the misfortune visited upon men who interfered with the banshee by taking her comb or challenging her. These tales point up the value of courteousness towards women, the avoidance of drink, violence and late hours. There is historical precedence for the banshee's appearance as a female spirit. In Genesis, Eve delivers the apple to Adam.
