Apologies for fact that photo of buds is slightly blurred. Buds are 2-3mm long.
No interactions present.
Consider Salix, from the buds against the case.
Interesting to see two different IDs from two I-Spot experts. Clearly a definite ID is not possible from these photos, as shown by the confidence levels you have given!
I'll return in a couple of months when leaves are present and add another observation with a comment that links to this one which will hopefully enable the ID to be confirmed.
