Hi John, I'm glad he is eating better! And it sounds like he is getting his appetite back.
I am curious though about how much pancur he was prescribed and how long ago he was on it. It is a very potent drug and is easy to overdose, and 2x a day regimen is very risky. I ask because of your point you made about liver detox.
Pancur (fenbendazole) is a very potent drug, and overdoses sadly happen too often when miscalculated. Overdoses can affect white blood cell formation in bone marrow, damage the lining of the crop and the wall of the small intestines, and cause secondary infections, anemia, and potential death. It is very hard on the bird's liver. Fenbendazole is usually dispensed in a liquid that is 100mg/ml. An average 350g pigeon should receive a range of 0.1 to 0.2ml of fenbendazole once a day for 3 days. It should be avoided due to toxicity even at published or recommend doses. See,

The jelly-like stools could also be from intestinal mucus, and can happen if there is a blockage. Ants do go after mucin.
Paratyphoid often will cause proventriculus inflammation initially, which will block food from entering the intestines. He also is drinking more than an average pigeon drinks, and that can be from the paratyphoid, being dehydrated, and also flushing out meds. A little crushed milk thistle seeds (silymarin) will do wonders helping his liver detox and flush out residual meds and bacterial endotoxins, but doing so on antibiotics will be somewhat counterproductive. A little fresh garlic juice in his water will be good as allicin will lesson inflammation, kill pathogenic bacteria, and help detox. It also has antiviral properties.
Your vet gave you good advice on using the electrolytes in the formula and allowing him to drink clean water to self regulate his sodium. I bet he was beating himself up for missing the boil in his initial exam, but it could have development since then, since boils often appear late during an infection. Also, massaging his crop is good advice especially if his proventriculus had or has inflammation. He could have been starving due to the blockage, making him weak and dehydrated, and unable to fight off the salmonella. The swelling should slowly go down like I said before. It is good that you noticed his crop not emptying
Starvation can also cause free radicals to build up, hence another good reason to detox and get his liver up to speed. He could also have a little flaxseed and safflower seeds as both have healthy Omega-3 fatty acids and other antioxidants.
How long ago did that wild bird come to you with paratyphoid?
The vaccine for multivalent paratyphus is a bit costly come to find out on Jedds.com and has to be kept cold during expedited 2-day air shipping. Maybe the vet can source it for a better price? I have read that even typhus vaccines can work against paratyphus, but I would have to dig into it further for effacy etc. The brand Jedds sell can be found at the manufacturer's site at

Wow, you do have quite the collection of birds! I didn't know you have a rescue center. I am considering going that route eventually and would like to apply for a wildlife rehab bird permit when I have the husbandry and means to go full time. I have just a few pigeons and a rescued African collared dove I saved from traffic. I also rescued a tame baby rabbit (domestic Belgium) from the city streets near LA, who I have here too. No one cared enough to list them as missing. Nor responded to my posts. They obviously landed in my path for a reason! I suspected my white African collared dove was an illegal dove release as she doesn't have a band like the ones sold to petstores.
In the past, I have rescued passerines (mainly Eurasian House sparrows), one was congenitally blind and had for several years. Years ago, I had more wild rescues. I rescued baby squirrels, freed bats from homes, saved a few mourning doves, robins, a cardnial hatchling, a tanager fledgling, and a cowbird fledgling - but had to send them to a wildlife center after initial care as they were orphans and injured. Fortunately, most of the aminals I come upon in need are the non-protected species - like they know haha.
Interesting to hear about the manganese deficiency on the islands. I didn't know that, but it makes sense with the pure basaltic lava. Mineral deficiency especially magnesium can cause angel wings, and recently there was a thread on this forum about a pigeon with that. I have had a wild house sparrow with hypocalcemia, but nothing beyond that fortunately. 10 years is a good old age for a sparrow!
I will definately have to set up something in the next day or two to share my collection. I'll have to message you directly with that.
