A great birthday gift for your daughter who likes ethnographic studies could be a book written by a famous ethnographer, such as "The Nuer: A Description of the Modes of Livelihood and Political Institutions of a Nilotic People" by E. E. Evans-Pritchard or "Argonauts of the Western Pacific" by Bronisław Malinowski. You could also consider getting her a subscription to a relevant academic journal or a book about a specific culture or society she is interested in studying. Alternatively, you could look into purchasing a unique art piece or handicraft from a specific culture that she admires, such as a traditional textile or a piece of pottery.
Or you can get her a star map with the date when she was born.
