Spent around 2 hours wandering the heath until darkness, no sign of any Owls. However, a Woodcock whizzed past just above my head and an astonishing spectacle of 97 Red Deer, including 2 Stags, were watched jumping the fence into another part of the heath. A Yellowhammer flew to roost, as did a Fieldfare and the local Corvids. It was a beautiful evening, and despite no sign of my hoped for quarry, a pleasing outing.
Drove home via East Harling Heath, stopping at various pull ins and listening for calls. Again, I left feeling frustrated but the habitat looks promising and persistence may just pay off.
