Julian,
this is really interesting. I have become aware that a Chinese
Elm Ulmus parvifolia in Dutton St Dickson has been messily
defoliated (tip pruned is better description, but less tidily
than when done by parrots). Last night Alison Rowell and I heard
flying foxes in this tree over a period of at least half an
hour. Might the scratch marks be from Flying Foxes?
