Tree was thought at first to be a Prunus sp. I now think it could be a Willow..?
No identification made yet.
No interactions present.
First pic. appears to show a small swelling where leaf & leaf-stalk join, so it may well be a Prunus sp.
See where your coming from. Come the season to be leafy I will go back and have another look.
