There are a fair number of shrubs which produce black berries so not easy to tell from the image. Viburnums of some sorts do. It could also be Aronia, Chokeberry, but then again....................

so do some dogwoods, Cornus sanguinea being one.

Thanks, Owdboggy and Seaburngirl. I am assuming it is unsafe to eat these?

Until a positive id is made, yes.

Could this be elderberry?

Still would need a clearer image to decide.Sorry.Elder has slightly serrated leaf edges.

the berry arrangement looks wrong for elderberry. Sorry.

The leaves look right for wild elderberry, to me.

Tugbrethil, they were in the wild. In the Scottish Highlands quite high and remote.

Tug you probably have different variety where you are!
The leaves don't look like the wild elderberry we have here.

It's hard to see, but the leaves looked opposite, pinnately compound, and lightly serrated, and the only berry that I know of that has that leaf arrangement and type of berry cluster branching is elderberry. The ones that grow wild in northern Arizona are more strongly serrated, but the species has a wide range, and is highly variable.
