If the crow in the black trailer was either of them, it probably would have been Raven, as Qrow most likely would have had his hands full getting Amber to safety. Cinder first visited their camp the night before the Black Trailer, hence Adam telling Blake that the train would be there "at dawn".

Then, we see Cinder, Mercury, and Emerald attack Amber on a cloudy day.

Then, Cinder goes and visits Adam again to use her new powers to threaten him into working with her, and just before she, Mercury, and Emerald beat up the White Fang members outside, Adam and the White Fang Lieutenant are talking about Blake.

Lieutenant: We'll find her, sir. (holds a hand up to his chest) I swear on my life.

Adam: (sharply) Forget it. It's time I returned to Mistral and...

Blake had just left Adam on the train, which was the end of the Black Trailer.

So, most likely, Cinder attacked Amber on the same day as the Black Trailer. Not necessarily at the same exact time that the Black Trailer was going on, but on the same day that it happened.
