We know that many of you have nest boxes and some of you have even rigged up nest-cams to see what goes on inside. But it鈥檚 not just birds that use these boxes 鈥� at this time of year they can make a nice cosy little home for a host of other creatures.
So why not turn on your nest-cam or have a peek inside and sends us images of anything interesting that you find inside.
Please either let us know with a Reply below, email us your photos to autumnwatch@bbc.co.uk, with the subject header NEST BOX or upload them to the Autumnwatch Flickr site.
We鈥檙e looking forward to hearing from you!
