Thanks for the thoughts. I read where it is advised not to clip a Corvid's wings, as they use them a lot for basic stability, say when moving around on a perch for example, or just a little jump up onto something. They are different from Parrots that way. I kept thinking that if i went back to the area and looked around, there was the chance he might show up, but after many times, no luck. I regularly go through the area, so he might show himself. Cool if he went back to the shop, it isn't far. Lately he had really been wanting to join other crows that were flying overhead, would jump off the bike to try to, but was on a line. Keeping a bird like that in captivity much restricts their strong natural tendency. I thought I might balance that out by good food and the changes of scenery and allowing him short flights on a line. Not the same, however, I could see that. When they are content, very nice critters to have around. They let you know that they are happy and show the sense of attachment.
