Qrow, along with Raven, may allude to Huginn and Muninn, a pair of ravens that flew all over the world to bring information to the god Odin.

During the scene where Yang talks about her search for Raven and being saved by her uncle Qrow in "Burning the Candle", the text on the chalkboard is an extract from a poem about Huginn and Muninn, two ravens from Norse mythology. The text supposedly reads:
 * Hugin and Munin fly each day over the spacious earth.
 * I fear for Hugin, that he not come back, yet more anxious am I for Munin.
 * I fear for Hugin, that he not come back, yet more anxious am I for Munin.
