Problem with missing fruit

karenannepeters

I am new to this forum, and not good with technology, but in desperation I'm seeking advice on missing fruit and in particular unripe pears and quinces.
In my small orchard I have 6 assorted pear trees amongst other fruit, and all bar 5 small fruits have disappeared virtually overnight with no debris or sign of removal. The trees were previously heavily laden with young fruit and we had a great crop last year.
The quince appears to be suffering the same fate but more slowly.
Any ideas? And, what to do to prevent next year?

Could be birds, they are after  my plums this year. Tree is a bit big to net which is what the books tell you to do.

It's a bit early for birds to attack fruit ... they'll be small and hard and unpleasant.  
Could it be the June Drop?

Or is your orchard visited by grey squirrels?

A few small apples have dropped and been left, but nothing found below the pear trees and almost all fruit disappeared from these trees. We do have squirrels but don't they usually leave a mess and part-chewed fruit? Plums are intact at the moment, and we always lose the cherries to birds so just accept that, or net the trees,  but they are a bit large now. We have 30 fruit trees so a bit of a task!
