We have lots of cover in the hedge bordering the veg garden at the back and an orchard full of birds voles and other wildlife behind that, - next to fields - but the feeders and bird table are in the (small) front garden which borders the lane and other building. They are there so that we can see them from inside the house! Nothing much has changed in the garden re cover recently although I did cut down all the 12 foot high hollyhocks which grew last year in the autumn, so maybe there just isn't enough for them to perch on - just some deciduous bushes. As I said our neighbours at the back have loads of feeders in their long gardens next to the orchard so the birds are definitely being fed well - I just want to see them like I used to!!
