Presumably urban/suburban covers gardens but does it also include parkland, cemetries etc within these areas?
If the parkland/ cemetery etc is big enough that a bird spends all, or almost all, of its time in it, I think the bird doesn’t much care that there are buildings on the outside, so I’d put it as woodland or scrubland depending on the state of growth of the trees. On the other hand, if it’s a small urban cemetery with little vegetation then it’s probably just F1 (urban human site).
