Shrike behind building

Just before lunch today, the fire alarm went off in the building and everybody was evacuated. I decided to go to the gravel hill behind building. I sat on the hill for a while thinking about stuff, and when I was about to leave, a bird flew from one of the trees and landed nearby. I only had my kit lens and I did the best I can with what I got, but the bird did not seem too typical. Looking closer, I realize it was a shrike - what species, I can't tell for sure. But from the bottom left photo, it looks like a juvenile.

Definitely the most exciting part of the day!
