Birds are trolls.
Spuddi (Low German for "sparrow") probably was the only living proof that not only house sparrows could sing DAMN WELL if they wanted to, but even the females! But she died last summer, and I missed the opportunity to make a video. It was hard enough to hear her sing. You had to sneak up to her very carefully, and she would only sing if the first rays of the morning sun hit the aviary. Otherwise she would just produce those rather irritating repetative and obnoxiously loud sparrow calls.
Spuddi came into my care after I found her half dead in the snow. Her beak was so overgrown due to its asymmetry that she could not feed herself any longer. After the beak got trimmed by the vet, she quickly regained her health. But after the beak kept growing back, the vet decided that she was unreleasable, and she became a permanent resident in my aviary. Spuddi found the periodic beak trimming procedure very displeasing, thus she never really became as tame as my other misfit birdies. But she became good friends with them. An aviary is never a good place for a wild bird, but I hope we still found the best solution for her.
