I noticed a hole about 2- 2.5 inches diameter, in a mature 
oaktree. The bark was gone, showing some old damage, 
and the hole seemed bored upwards, under the remaining 
bark. the wood with no bark could be rotting I suppose, from 
the inside.
There is a fallout trail of reddened, powdered wood below it.
Could this be from the heartwood? If so, the hole must go 
some way into the tree.
With the hole being so wide at the entrance, I am confused 
as to what it might be.
Perhaps deathwatch beetle?

I wouldn't like to meet it if it was, their exit holes are at most 5mm 
across!

How high up the tree is the hole?

I guess 6 1/2 ft -  7ft

Sounds more like a bird, if it was around here I'd say Parakeet.
