Blue tit investigating our box
Hi Rob, personally, I wouldn't use tumble dryer material for the reasons that Debs mentioned - just scroll down for her comment on this thread. I put sheep wool out and often moss which I stuff into one of the fat cake square mesh feeders so they can just pull out what they need.
Sunday March 24th
Two blue tits this morning ( 10am - 12ish) very busy between both bird boxes, which confused me, seemed to be in and out. Obviously only one camera, so not sure what’s in the older box.
Later one bird kept visiting in and out over an hour or two, would fan, but didn’t seem to be bringing any material, but would remove the odd piece.
It does seem to be the same bird which is staying and has stayed overnight for last 3/4 weeks
Returned again around 1.30pm with a lot of pecking around entrance hole from inside and out
