The Estrie was a female vampire spirit that assumed the shape of a woman at her will. It is said that they can also turn into birds, cats, and other various animals.
The Estrie preyed on Hebrew people, especially men and children
The vampire creature fed on blood to survive, and by some stories were identical to Succubi.
Because the Estrie can take human form, it is not uncommon for stories to claim they lived among humans in order to satisfy her need for blood.
Estries were believed to be able to walk into holy places, and even seek prayer for healing.
In order to kill an Estries, dirt must be packed into its mouth at the time of burial, decapitate the body, or burn the body. Later stories, claim that the vampire creature was vulnerable to silver bullets, wooden stakes, blessed weapons, and holy water.
