Cherry tree help

[Mick]

I planted two cherry trees two years ago, they are on dwarf rootstock so are not very tall, around five feet max.

Last year they had quite a bit of fruit on them, but got eaten by the birds, and we didn't end up with one cherry for ourselves. Also a couple of braches got broken where the birds (pigeon) had landed on them.  What's the best way to keep the birds off these trees?  I also have the same problem with a couple of small Victoria plum trees.

I've though about a makeshift frame covered in netting, but to be honest I haven't a clue. Any tip welcome.
