The white Nevermores (they were Nevermores, not doves) were most likely Dust. I'm pretty certain of it. It appears that, whenever a Schnee mixes Dust directly with their glyph, the glyph takes on a very different appearance than the plain Schnee snowflake one. Note the appearance of Winter's glyph when she made the Nevermores, then compare to the appearance of Weiss' haste glyph. Completely different from their plain glyphs.

Weiss' haste glyph is made by mixing yellow Dust with a glyph, as evidenced by Painting the Town, when Myrtenaster's blade glowed yellow, then fired a yellow beam to the ground to form the haste glyph under Blake.

Winter made steam earlier in the fight, and Miles listed steam as a type of Dust you can create by mixing fire and water Dust. When Qrow hit the Nevermores, they burst into clouds, so it's likely that the Nevermores were made of condensed steam. Winter mixed Dust with her glyph in order to make the birds, and since Winter and Weiss' glyphs control motion, she was able to control the Nevermores.
