My brother had a pretty bad disaster. Put together his computer and we have 2 cockatiels who like to play around in dark places, anyways he left it on the floor in his room to use the bathroom as mother nature called. I walked into his room and I found our two birds running around his case, I chased them out but I knew it was too late, feathers and bird shit were all over the motherboard. I'm pretty sure feathers conduct electricity because he tried to boot it up and it was black screen lol.
