Where have all the birds gone

Am wondering if this could be due to more folk feeding birds during the British Garden Birdwatch weekend so more choice of feeding stations before they reach yours?

Over what time period? Has anything changed? Garden been cleared of trees/shrubs/hedge? New cat(s) to the area? Roof repairs made to your house or houses in the immediate area?

We have observed the same down on the South Coast. Very few visits to our feeders or the birdbaths. This is a great contrast to previous years. The garden hasn't changed but a neighbour now has three cats and we often see them stalking squirrels and birds. We weren't sure if this was the cause or just a random observation. We know that other neighbours feed foxes and I have caught them in the past on a camera trap, could that also contribute?

I live in South Wales, I have been wondering for months why I don’t hear the beautiful dawn chorus anymore, there is an extreme lack of birds, bees, wasps, and butterflies. I have been watching for months but nothing, there is a horrible silence and a severe lack of birds.
I see pigeons, crows, magpies and the odd buzzard and the other day I saw a female blackbird. No starlings, sparrows, robins, swifts, swallows, house martins, blue tits, nothing, it’s like they have all vanished.
it’s not just me saying this, I have spoken to many people who are all saying the same thing, something is missing.
