Birds losing their food supply

Hi all

I've been feeding garden birds since I moved here 10 years ago and have many regulars. My plan to stay for the rest of my days unfortunately has changed. I'm very concerned about how the birds here will survive. I have two neighbours and neither feed them.

I want to do what's going to give them a better chance to survive. I'm moving in February. Shall I start reducing their food weekly now? Or feed them the current amount to help get them through the winter then reduce? Or is there a better way?

Thanks in advance
