Corvid in Death Valley ID

Hi,

I'm not from the U.S.A. and am a bit confused about this bird I saw in Death Valley National Park, CA. I've only got the photo and can't remember how big it was for ID purposes but if anyone can tell me if it's a common raven or an american crow I'd really appreciate it!

Cheers,

Tim

Looks like it's calling there - can you remember what it sounded like?

I think that was just the panting - was a pretty hot day from memory. Can't remember any vocalisations sorry.
