Before we "saw" him literally turn into a crow, my leading theory for what his link was with the crows was that they were his semblance... Like, just like Sun can create light clones or the Schnee's summoning glyphs create aura constructs shaped like defeated enemies, Qrow could make aura constructs shaped like crows...

On a more OP version of said theory, if one of his crows spotted something of interest, it could turn into a clone of Qrow. The more crows he merged into the clone, the closer to the real Qrow's power it got.
