Hi all, I'm quite new to this platform so please bear with me. I have recently decided that I would like to be able to care for a corvid, preferably a jackdaw or crow as these are the best for the space I currently have. I've been doing plenty of research online and on this website especially, however I was looking for some tips in regards to keeping one of these birds. I have been working in an Owl Education Centre so I certainly have some experience with birds, however that is as far as my experience goes. Of course, if anyone has more experience than I do and wishes to tell me to consider other options for a bird, please do so. In regards to what I need to know, I'm uncertain of the certain dimensions required for an outside aviary for a corvid, other than that it most likely will be larger than that for a parrot. I'm also unaware of the specific requirements for how much flying these birds need (and training them to do so of course, although I have a vague idea of how to do so for birds of prey, are they similar in any way?). Also, how is it that I can ensure that by allowing my bird to fly freely outside, I will not lose it? I ask this because I do not wish to put a telemetry on my bird whenever I have it outside of its aviary, or in my home with a door or window open, for example. If anyone could answer these burning questions of mine, it would be greatly appreciated.
