An Owelry is an abode or a haunt of owls
owlery
Use incendio on the vine to the left of the door. After that, you will be able to climb up the side of the owlery, and across ledges to an open window.
The owlery is on the grounds, apart from the main building. Take the covered bridge away from the school and turn to your right when you get to the other side. The owlery is the tower in front of you. If you still have trouble finding it, or any other place in Hogwarts, try summoning Nearly Headless Nick to guide you.
It is called the Owlery and it is located at the top of the West Tower.
When you finish putting the snack boxes in place, go all the way to the top of the owlery and go inside the thing that looks like a fire place. There'll be a broken ladder in there that you need to fix. When you fix it merely walk in front of it and that's how you get out.
When you finish with the snackboxes, you have to go all the way to the top of the owlery. You'll see something that look like a fireplace, go in it. There you'll find a broken ladder. Fix it with "Reparo" and just walk toward it to get out.

First, Fire the "evil" tree behind Colin by Incendio with helps of Hermione, Ron and Colin. Climbing up the Owlery house by the "thing" at the corner of the stair and the "evil" tree. After climbing to the first , Move around on the left to get to the open window of the Owlery, get in.....then Colin will throw 5 boxes into and you just use Wingadium Leviosa to put each box into the right places for delivery. After put all 5 boxes into the right places. Go up to the top floor by stair, go through the open door there, you will see the broken bench, use reparo to fix it , then climb up to get out of the Owlery Then climb down until you go to the ground. Remmember, choose the "thing" without broken to climb continuously, if it broke, move around the Owlery to find the another one without broken to climb up high. Doing the same when going down. Enjoy!
No, Hermione always had to borrow one of the owls from the owlery at Hogwarts to deliver a parcel or letter.
