Feeding signs, freshly opened split hazelnut shells.
Small pile under the squirrel feeder "around the back" ---

I had carefully checked and cleared all I could find from this patch last night, so there is still a [red] squirrel somewhere !
The trail-cam will be going out to cover the feeder tonight / tomorrow.

{e2a - a russet red streak was observed crossing the back garden later in the day}
