Greetings. A bit of background before a question:

I live in an apartment complex, in northern Illinois, where I have been feeding peanuts to the resident chipmunk population. I've been doing so for about 4 years now. I grew up much of the time in a very lightly populated northern woodland environment, with a number of U.S. Park Service and Forestry Service relatives, so my normal policy towards wild animals is, "Don't touch. Don't feed Just let let 'em be.", but in this I had made an exception. The previous resident of the apartment already been feeding them, so they had already become acclimated to such contact, and where already begging anyway.

At this point, I now have a population ranging from less than a year old, to more than 4 years of age. Most have names, and I can recognize individuals by behavior and markings.

Yearly, females often herd their children to the feeding spot (The wall of our sunken patio), although I've never determined if this is active teaching on their part, or that the youngsters just happen to follow the mothers in when they come for the daily ration. Either way, the end result is a steady population from year to year.

This morning, I went out to the patio, has I do frequently. After a very short time, a very young little fella came out from underneath our grill, about foot away from where I was standing, and began to wobble it's way around the porch floor. I have not seen this particular one before, but it's main interest was a few empty peanut shells that I had not yet cleaned up.

I tossed down a few fresh and it quite enthusiastically grabbed those up, and proceeded to shell those. Unusual, has most of "my" chipmunks had to be taught that peanuts contain food. So now I have a tiny little stray youngster, who knows what peanuts are, and what to do with them. It isn't showing any signs of fear, though I've never seen it before, and it's happily having some breakfast.

The problem is, it kept swaying and falling over, the whole time this was going on. It also soon became apparent that it was not at all likely to get itself out of the patio area on it's own.

Figuring that, the next thing I did was to go get a cardboard box. Catching him/her was easy. Took about 30 seconds, and a slight nudge with a broom. Once in the box, it got very active, but once released to the surrounding ground level flower beds, it exited the box has if this was a normal every day thing, and proceeded to root around the mulch like nothing had happened. Still no signs of fear. No hint at all of even slight distress in fact. Never even bushed out it's tail. Handed out a few more nuts at that point, and it happily took those has well.

After about 10 minutes, it decided it was time to go elsewhere, and began to make it's way back along the wall of the building. A common route, often taken by one of my 4 year old females. That particular female is also the one most likely to bring children, so I suspected it to be one of hers after that. (I'm thinking she might have brought it by very early, it fell into the patio area, and now they're separated due to the inability of the little guy to get out. I haven't seen any adults around near-by at any rate, other than one of the males that sits out in the bushes in the mornings.)

Over the course of traveling about 20 feet, it fell over on it's side about 30 times. It then stopped, took time to wash itself, sat and wobbled a bit, and finally appeared to take a nap. It paid only slight attention when the local chipmunk warning net started alerting to a dog being walked, and that was a concern due to the high chance of an appearance by a local cat at this time of day. Everybody else went to the "safe spots", has is normal. The little fella looked around, but went back to sleep in short order.

Because of the high threat of cats, I stayed out for quite awhile watching over it it, (for the better part of the next hour), until the mowers came for the lawn. That woke it up, but no attempt was made to flee. The mowers passed within 4 feet, without incident.

After they left, the little guy did then get going again. It rooted around the mulch a bit, and the continued to stumble it's way back the rest of the way, towards where the previously mentioned adult female goes. It never made it more than a foot without falling on it's side however.

Other than the walking issue , the apparent obliviousness to potential danger, and the strange choice of nap locations, it appeared healthy. Glossy clean coat. No visible flies, parasites, wounds, or any other obvious symptoms that I could see. While it wasn't moving the fastest I've ever seen a chipmunk go in "normal" speed walking, i wouldn't exactly say lethargic either. It didn't seem pained in any way.

I would best describe the behavior has completely crocked, which was actually my first conclusion. Only problem now is that I'm not so sure. I've seen it still doing this stumble routine, hours later, and I'm no longer thinking fermented berries any more.

And so, this all leads me now to the question part:

I've spent a few hours now researching, and that has led me here. I really have no solid conclusion, and it's starting to drive be a bit batty.

Does anybody think I have come across anything that might fall under the umbrella of a known disease, defect, or otherwise? I mostly maintain a hands off approach, other than running off the earlier mentioned cat, and let nature take it's course, but in this case I am worried that this thing might effect the rest of the population. However, I'm far from being a chipmunk expert, and I am unable to identify for sure what I am actually seeing. I'm just trying to find some answers before I worry myself beyond need.

Thanks for reading this novel. Any opinions would be most helpful, if only to ease my mind that I'm not dealing with some kind of strange plague, lol.

Hi and welcome to the TSB! I am also a feeder/watcher of the wilds in my yard!


There are a number of possibilities which this little Chip. Some type of head trauma from a fall can cause loss of balance, circling behaviors, fine and gross motor issues etc. This can sometime resolve over time on its own although often is treated with a steroid like prednisone if the critter is captured.

Animals can get drunk on fermented fruit. This might be the best case scenario for this little chip. If so, it should be fine tomorrow BUT it has to survive till then. It is an easy target for cats, dogs, raccoons, birds etc and may not survive the day if it does not find shelter.

There are some pretty nasty parasitic infestations that can cause damage to the brain. A type of roundworm that is extremely common in raccoons (and present in their poop) called Baylisascaris can lead to irreversible brain and/or organ damage. Raccoon poop contains the eggs of this work and if these are eaten or inhaled they eventually work their way into organs. This worm is also very dangerous to humans. There is no real treatment and this chip will not long survive if this is the case.

Any chance that someone left poison (intentionally) or some type of toxin around? Anything from engine coolant, pesticides to intentional poisoning for rodents like rats/mice could also lead to behavior like this.

By far the least likely possibility is rabies. Almost all mammals can be infected with rabies but the chance of a chip being bit and not killed by an infected animal is EXTREMELY remote. I mention this only because it is theoretically possible and the symptoms (clummyness, no fear) resemble a type of rabies. However, this is EXTREMELY, EXTREMELY unlikely.

I would say that he should probably be brought in for observation. He will not survive long if he keeps behaving like that. Perhaps we could locate a rehabber near you?

Ahhh, Thank you. Exactly the type of feedback I was looking for.

Well, let's see. A fall is very possible. It's more than a three foot drop to a concrete floor, and I can very much see that happening. Wouldn't be the first.

Fruit was my first guess. Plenty of it around. Some from a lady that throws various fruits and breads out for the grey squirrels, but we also have naturally occurring berries of various types. There are dumpsters in the parking lot's that could contain such things has well, and the chips climb all over those.

Unfortunately, many of the chips hang out on and under the big concrete slabs/steps at the entrances to the buildings. These are also frequently burrowed under by skunks and opossum. Racoon sightings are a weekly thing has well. (So many that because of this I spend quite a bit of time at night striking a flame on my lighter and talking to all three, so that they don't wander too close without knowing I'm there. Especially the skunk, lol.) So, the possibility of contaminated poo probably exists there. That alone will likely result in my deciding to involve a qualified expert in this case. Don't need something nasty spreading through.

Poisons. Only real source of poison that I can think of would be a coolant leak from one of the air conditioners. They drip down condensation, and the chippies drink from that. Maintenance is pretty on the ball, but the conditioners have been known to leak now and again, being over 30 years old. The lawn care guys sprayed a defoliant today, but that was only in the last hour. The bug guy hasn't been here yet this year, has far has I know, but he does spray for carpenter ants and other wood pests on the decks. Chippies do come in contact with those surfaces.

Lastly, the rabies. I too think this is highly unlikely. While not unknown in my area, it is extremely uncommon, and generally quickly taken care of. We are near a number of state and county preserves, and word is spread fairly quickly when an animal is found with such illnesses. It could happen, but I'm not really worried.

Basically, from your suggestions, I have also come to the conclusion that this probably should go to a more qualified person for observation. I'm set in that regards, and know a few people I will be calling after this post. There are a few rehab facilities around me that will be able to either handle this, or send me to the right place. I'm pretty confident about it's current location, so that it can be re-trapped, but in retrospect I probably shouldn't have let it go after the first time I caught it. Unfortunately I was more worried about that cat catching a fruit drunk chipmunk in a confined space than I was about any serious illness at that point.

At any rate, thank you again, very much. Now that I know some possibilities, and have a plan, I'm feeling much better about it. Hopefully we'll get things sorted out fine for the little fella now. :thumbsup

Please let us know if you catch him and what the outcome is? Thanks for looking out for this little fellow.:clap

Certainly. I'll definitely pass the word when I know more.

Has for currently, I just contacted the local preservation district's rehab program. They only have three people on staff full time, and apparently the guy currently on duty is out in the woods somewhere at the moment. Going to give me a call back. I've gone through them before though, and they've always been very quick, and very helpful.

Update:

The wonders of cellphones. Got my call back from the woods. :grin2

Ok, went out and found her sleeping where I saw her last. (We know it's a her now.) It was almost has easy to catch her has it was the first time, which I'm sort of surprised about. The cat must have not got let out today.

She's being a little active in a shoebox at the moment, but still has balance issues. She's also gotten a bit twitchy, and I'm not liking the breathing pattern, although that may just be the stress of being put in a box twice in one day. However, one eye seems to have bulged out slightly since this morning, which unfortunately has me thinking head injury at this time.

We now take a little trip to drop her off at the center. They'll look at her there, and either handle things themselves, or transfer her to a volunteer. Apparently they have a veterinarian or two that take some of these cases. I'm guessing she'll end up with the vet though, now that I've seen some actual physical swelling of that eye. Hopefully it's treatable.

I'm normally allergic to double posts. Triple posts have been known to cause physical pain. But it would seem there is a time limit on post edits here, so....:sorry :grin3

Final update most likely:

The chipmunk has been looked over, and it is indeed most likely a fall injury.

There is some swelling, and possibly some damage to the bone around the eye socket. It's definitely a possibility that there is internal damage in there somewhere that is effecting her balance, but they're not sure yet how bad that might be.

She is responding more like what you would expect now though, which is probably a good thing. (The passive, no fear behavior was very unsettling. That much I can testify.) Now she actually moves away from people, and she is bushing up her tail, and giving of some anger/warning type vocalizations. Appetite is strong, and while she'll sleep if left alone, she's capable of staying awake for lengthy periods when people are around. I'm told she has also done some exploring of the new environment.

She's going to stay overnight with the conservation district people, and then most likely go with a local volunteer vet tomorrow, who will take her home and do all she can for the little chippie. Apparently she takes in some of the small rodents and birds from time to time, but the chipmunk is not far from the age where she would be off on her own, so they will try to release her into the wild again if she recovers well enough. They do not know the totality of the injury just yet though. The improvement in behavior shown so far is positive though.

So that's it. Hopefully a tragedy averted.

Thanks again, (and I'm sure the little fuzzball would thank you has well. :grin2 )

Sounds somewhat promising! You did a good deed rescuing such a small, helpless critter!:thumbsup
