I thought I saw a man dragging a reluctant camel along in the distance. Wow, a camel in Sheffield.
Then I magnified it and realised it was smoke coming from one of the chimneys making shapes. Silly me.
If you want to see urban peregrines, then Sheffield is the place to come. The nest is placed on church tower that's no too high. When they're fledging you get some brilliant views when they're flying at tree top height.
