Can anyone identify what blue type of Berry's there's are

Can anyone identify what blue type of Berry's there's are don't know if there Bilberries or blue berry s or poison but do have red inner fresh those and looks like big seeds

Mahonia maybe?

If they are I think they're technically edible, but you wouldn't want to. Birds love them though

Mahonia berries tend to be in longer tassels, reflecting the shape of the flower sprays. Depending on the size of those leaves,it looks like Berberis darwinii.

Just to confuse, wiki tells me that, as of 2023, Mahonia has been subsumed into Berberis, so Mahonia aquifolium is now Berberis aquifolium.

@Milkey96th Never eat any kind of berry unless you are absolutely sure what they are, and that they are edible.

Definitely not bilberries which grow in moorland and don't look like that, and not blueberries either.

Looks like Mahonia to me. Don't eat them!

What do you think about the arrangement of the berries? Mahonia has long tassels of flowers, so obviously the berries are in the same arrangement. These are tight little bunches of berries with all the stalks coming from the same point. Also, the leaf length is no more than twice the diameter of the berry, whereas even Mahonia aquifolium would have leaves at least 4 times the diameter of the berries.

This demonstrates the long tassels of berries and longer leaves of Mahonia aquifolium.

I've seen these before, I don't know the name but they taste disgusting so don't eat them! I tried one once in my mates parents garden.

These look like Oregon grape to me. If they are, they're technically edible but also taste disgusting so I wouldn't!

Not Oregon grape (Mahonia sp) for reasons given above

Berberis darwini? They look a bit less tassley in this pic?

@MereDintofPandiculation
I guess I was majoring on the bilberries / blueberries bit of OP's post and then thinking it was probably Mahonia. I agree about the distribution of the berries - though mine are never that abundant! - and OP's pic is not the clearest.

@GrannyAchingsShepherdsHut suggestion looks a good shout.

Damsons?

"Depending on the size of those leaves,it looks like Berberis darwinii."

Not with holly-leaf shaped leaves. And we're (the mahonia/berberis advocates) all assuming the berries are 1cm or less, partly because of the remains of the flower on the end - that would be one hell of a style/stigma if scaled up to damson size. And because OP called them berries, which are usually smaller.

There growing in some garden and growing over the fence so not sure if there edible

We have similar/ the same growing at work , they have about 2 inch long thorns on them.
I have tried them ( cos I am a fool ) they are very astringent, like unripe quince .
They also stain everything they touch if you split them open .
Birds love them and cover all the cars in purple poo !
