Greetings Eileen:
Many juvenile oak (Quercus) trees will retain their leaves during the dormant season -- this phenomenon is referred to as "marcescence."
However, oak is not alone with regard to this phenomenon: witch-hazel, American beech. eastern hophornbeam / ironwood, and American hornbeam / musclewood.
