I've not been squirrel hunting for a while but have recently rejoined my local red squirrel group having stopped doing squirrel control in 2019 when i got cancer.

The critters did seem quite nervous today, quite twitchy and thinking about it not a single one approached from the ground, when the past three times I've been to the woods to I've seen some them of them at ground level.
