If you miss them Howard here's a picture of one on her nest at the far end of the lake - but do you see what's sitting in front of her?
This was about five years ago and I was taking shots of the waterfall when something made me look around .... and there they were.
Then came the tricky bit. I had to turn the BIG tripod around 180 deg. and change the camera lens without scaring the squirrel; but I managed it somehow and just kept he shutter going.
