Fruity signs of life - 2021

I'm hoping this is a Mirabelle plum! 
It flowered for the first time last year but there were no fruits, masses of blossom this year, so, fingers crossed for pollination.

Wood pigeons round here seem to have acquired a taste for the young fruitlets of plums and I think last year went for pears as well so hope yours are safe.

Yes, they eat all the buds - they ate 90% last year and they seem to be going for gold this year.
I never used to have this trouble?

I don't think we used to have as many pigeons, farmers used to keep the numbers down. I not yet seen signs of them eating fruit buds but something is chucking all the horse chestnut buds onto the ground, maybe that's pigeons.
