Pam, first of all let's hope it's just the weather, and your Rowan
will be fine next year.

That would be wonderful, I'll wait and see!

Otherwise, this is what Hugh McAllister writes in his excellent "The
Genus Sorbus" (Kew): "... Sorbus trunks are short lived. This need
not deter gardeners or landscapers from taking a longer term view.
In the wild, even though individual trunks may become infected by
fungi and start to die back after about forty years, all species
freely produce stool shoots from the base of their main trunks and
individuals can produce successive generations of trunks. Thus, in
situations where trees are grown on their own roots (i.e. not
grafted) and do not need to be grown on a single trunk, moribund
old trunks can be cut out and stool shoots allowed to replace them."

So, even if you do need to take out the main trunk, there's hope
that you (and the birds) will still enjoy it for many years.

I've been reading up on google about the tree and find their life expectancy
can be up to 100 years so mine's only a quarter of the way to that figure
:-)
I'll look for some stool shoots and see if I can replace it with one of them
But I think the best thing for now is to wait and see what happens next
year.

HTH

It does, indeed, Emery, thanks very much:-)
