on the 22nd of last month (april) I was still up at 2am (like most nights) heard the lorikeets in my big tree fly off in a fuss then as they went into the distance heard this loud skreetching comeing from my back yard and knew straight away it was a bird. I rushed outside with my flashlight and found this little fella screaming out for help.. I kept him warm overnight until the morning when my mother in-law called her wildlife carer friend who came to pick hum up.. He wasnt using his legs at all but did use it's wings with no trouble (it was fun trying to catch while flapping around the yard). He had no signs of injury external or internal (no broken bones) but was found to be riddled with tape worm 
2 weeks later I got an email saying he's regained use of his legs and after being a wobble bum "paddle pop" has made a full recovery 
I just emailed her back asking for a tad more info eg why couldnt he use his legs? etc but I am just so happy the carer and myself gave this little guy a second chance at life :)
Hi cassie, thanks for caring and sharing your story. My son and I do anmal rescue, and of late there seems to be more and more birds. Most of ours are traumatic injuries, and a bird that can't be "repaired and rehabillitated" won't survive in the wild, and so many are euthenised (after consultation with a vet - we have a very bird friendly vet). This is sometimes done via a phone consultation, especially if injuries or very obvious.
Tapeworms are quite common, and can have many and varied symptoms. I suspect if this bird was badly infected, then it's lost function may be due to malnutrition and dehydration. It could by the sound of it flap it's wings, but not fly very well, probably lacking enough energy to do this.
To check for dehydration, gather a fold of skin between your finger and thumb (the bird's breast is the best site, beware not to be bitten!), when released it should return to it's original position in 1-2 seconds. If it remains 'peaky" then it is dehydrated. This principle applies to any creature (human or otherwise). Usually on humans, pinch the skin on the back of the hand. Behind the head on the neck works for most mammals.

That's a juvenile bird too, hence the black looking bill. The green towel suits nicely.
