answer:Leave the window or whatever entry source open and allow it to tend to it’s nestlings. I don’t know where you live, but most songbirds are protected by law in many states and to disturb nesting birds is illegal. A yellow and black bird is most likely a Warbler species. You could try to relocate the nest outside but very nearby the entrance to your room, but, to move and re-secure the nest in a safe place is iffy, you risk damaging the nest even though the mother bird would, most likely, continue to care for them if the nest is placed within earshot and is in a safe, sheltered and seclude place, not out in the open. Your only other option is to contact a local wildlife rescue and they may be able to take the nestling, but, capturing the parent bird is out of the question.
