What are these berries (And nut)?!

[Smilesbetter]

Hello! So the other day I discovered that the city is full of berries, but I have no idea what any of them are, shamefully, and I'd like to start learning. Unfortunately it turns out that Google has waaay too much information and wasn't much help for me, so, do you guys know what these are? I tried to get the leaves in the photos too to help in identification.Sorry, I had to just put the direct Photobucket addresses coz the forum said the photos were too many pixels and I haven't the foggiest how to change that :S

These first ones were round the corner from my flat. The leaves are tiny and I couldn't find any berried online that looked like this and had leaves that small. The berries were on fairly long, dark stalks. The bush was growing in a park, presumably with quite sandy soil (The same as everything else photographed here, Berlin has very sandy soil).

Is this a hazelnut? It looks like them but I couldn't tell. i'm new to all this plant ID business unfortunately.

So, any ideas what they are?

Black rose hip, beech (I think), don't know thw pink berry, initially thought rowan but they are in bunches and the leaves are wrong. Then elderberry, last mahonia.

All edible except the pink one which I would say avoid if you don't know what it is. Google these for more info.

Thanks!! My man is hoping to make some local Berlin wildberry infused vodkas so he will be delighted to hear this. Great to know there are so many edible berries so close to where I live in the city. Ironically, my parents' house, which is in a small town in Scotland surrounded by farmland, doesn't have anywhere near as much great food growing as I seem to here. And thats even including the stuff the farm grows haha.

Out here there is every fruit and nut you could possibly want growing on the sides of the roads and between fields, it's a forager's paradise. The gardens are all planted with fruit and nut trees too, though a lot of our's were chopped down by the previous owner. I have added a Bramley apple to the mix. What we don't have we are given by neighbours or told to help ourselves to what overhangs. No excuse for going hungry here.

I have found out now that the nut is in fact Turkish Hazel (Corylus colurna) which is like Common Hazel only much smaller and with a much thicker nut shell.

Also I have noticed that there are red Rose Hips growing in the same line of bushes as the black Rose Hips. Thanks for the help with IDing! Haven't picked any again as they aren't looking their best any more and there isn't much left, but will make sure to take note of a few recipes to use them in for next year as there is a whole row of bushes of both colours in the park just behind my flat so there will be plenty fruit to pick if I time it right.

I have found a great website Mundraub which is a German interactive map of foragable food. It has a few in the UK even but looooads in Germany. This is where I am lucky living in a city too as my local area is pretty well marked out in it. I have discovered through it that there is wild hops, cherries, blue berries and all sorts of other things growing wild and within a short walk from my flat. It's great for me as a beginner coz I can see where something should be, look it up to find out what I can use it for and learn more about it and then go off to spot it. Is there a website like that fir the UK at all?
