At first - I thought this would make an interesting article somewhere. Something like, "House Sparrow (Passer domesticus), surviving despite limb impairment" ... After throwing up in my mouth a little bit, I wrote this post.
Waaay back when things were green - I saw this House Sparrow at my parents place in Burlington. They had seen him around for quite some time. In the above photo, the posture isn't particularly unusual - especially among young (lazy) birds.
I was unable to capture the exact sequence - but the bird was well enough to consider bathing. In the above image, he is ready for launch. Below - he has flapped his way across the entire birdbath - through the water - and ended up on the other side.
Feeding didn't seem like much of an issue either. In the image below, he had flown up to the feeder and carefully flopped into the perching ring.
Overall it was rather sad to see the loss of function - but also uplifting to see him go about his daily activities without too much difficulty.
