Oak trees still in leaf in East Yorkshire

A frost severe enough will remove leaves but without the frost the
normal cycle will run through. I saw some conker trees lose all their
leaves one spring but they regrew. They don't get that chance on
whatever deciduous trees still have them in December.

American oak is not deciduous -though these look more like sessiles.
Some deciduous oaks (if not all kinds?) have two leaf growths; sending
out a burst of new leaves in September, if I remember correctly.

Far be it from me to wonder off topic but:
Since most of these kinds of deciduous oaks cross breed, can they be
described as "species" would anyone know?
