Thank you very much for helping this wayward bird, the bird more than likely is a loft bird, is the bird Banded?
The little bird was starving, the lack of nutrition breaks down there immune system and it appears this little one is ill.
If possible this bird could use some Bird Biotic,
Bird antibiotic for pet birds
This medication might be sold at your pet shop; Doxycycline is the drug we are looking for.
The bird has been wondering for some time now, its apparent the little one is used to humans, how he/she became lost is a mystery, but when things get ruff they will always find a human for help.
The bird will not survive if released, at least not in his/her current condition.
It will take a month (maybe longer) to get this little one back into good health and spirits.
I don’t know the level of commitment you are willing to go but if possible a 5 sided one foot square box (wood) turned on its side and hung towards the top of the outdoor aviary will help the bird feel secure and safe, even a handful of straw will help the bird.
The temps you speak of are tolerable, the Pigeon is a very hearty bird, but they do need shelter and a sick bird needs this shelter even more, feeling safe and out of the elements helps the bird to get healthy again.
Such a pretty little bird, I would offer to cover the cost to ship the bird to me but I simply can’t afford the costs right now, that poor little bird is not Feral and won’t survive on his-her own unless maybe there’s a feral flock that the bird can join up with, this gives the bird a fighting chance.
Otherwise a domesticated Pigeon (lost) is doomed to a life of wondering and starvation, unless they join up with a feral flock somewhere.
It costs $11.00 dollars to have a live bird shipping box sent out, then another $27.00 to ship, I simply don’t have the funds right now, loosing my roofing job has really hurt my rescue abilities.
I have the medications to help the bird, I simply can’t afford the shipping right now, I pray you understand.
The seed and fresh water will help the bird a great deal; I suspect there’s a little food poisoning or flu like symptoms this little bird is struggling with.
Thank you again for all you are doing to help this little bird, he’she would surely have perished without your kindness.
Sending prayer to both of you!
Peace
