Red berries

I have no idea what these are. I need to go off and do some research! Taken at eye level at Five Rivers, I could hardly resist taking these berries' portrait in the late afternoon sun.

It's a tree, or very large bush, and it was covered in a heavy crop of these berries. I didn't taste one although I must admit being tempted! My Mum always called 'unknown' berries bird berries in the hopes we children wouldn't eat them. It worked Mum!
