Food Sources
I am of the opinion that no squirrel hunter can really get good at his craft until he can identify the foods squirrels use and the trees that the food comes from.
Of course there are other food sources that squirrels use that do not come from trees. They will eat most grains from farm fields and probably some fruits, drupes and berries from plants.
At this point in this discussion, we will focus on the trees that produce mast or a source of food that squirrels use.
These types of trees and their existence will vary from state to state. Each hunter has to learn the ones that are in his specific area.
It also is of use to know when each species of tree has its mast ripen to the extent that squirrels start to use them. Knowing where to find a single kind of tree is also of use. That means you must study the kind of habitat that you find such a tree in so you will know what kind of habitat to look in to find others of its kind.
When you find several squirrels in one tree at one time, you can bet it is probably a food source that they are fond of and that at that point in time, if you are able to find other trees of its kind, you will probably find more squirrels! Knowing how to identify the tree and the habitat it prefers, you will be able to find other trees like it and therefore more squirrels.
It is my intention to go through a list of tree types and the approximate time that these trees ripen mast to the extent that it is ready for squirrels. In actuality, these times will vary from north to south as the seasons are different. The times I will refer to relate to most of Illinois. Remember that as you go south from Illinois, that mast may become ready earlier and just the opposite will occur going in the opposite direction.
As the Illinois season starts on the 1st day of Aug. I will start with that date and then continue on for what I know about one cycle of growth. (A whole year)
Of course, if any of you have different specie to add to this timetable, please do so. Remember to give a location for the timetable so we can get an idea of the difference in availability from one region to the next.
This topic of trees may take a few installments and will also not be a definitive list. I am just relating my observations and experiences in my state over the period of 44 years of squirrel hunting.
Aug 1 has been the squirrel opener in southern Ill. for the 44 years I have been hunting them. One thing you can rely on is that it will be HOT!
There will be lots of skeeters, chiggers and ticks as well. A lot of sweating will be in order to get any hunting in.
In Aug. the first 2 hours of daylight and the last hour before dark are going to be best for hunting. Squirrels will move more in the coolest daylight hours at that time. This means getting into the woods before light and sitting in a spot where you expect them to be or to come to in order to feed.
The knowledge of what kinds of food is ripe and ready will help put you in a better spot at daylight, if you know where the food sources are.
One of the things that squirrels (especially young squirrels) eat in Aug. is black (wild) cherries. These are easy for young squirrels to eat as they have no hard shell to cut through. They are usually plentiful as well.
The only noise that squirrels make while eating them is the movements from branch to branch as they move about the tree in search of the cherries.
You will also, on occasion, find other varmints up a cherry tree. Raccoons, Possums and every bird in the woods will be up in there after those cherries.
I have found enough squirrels in black cherry trees in August to make the cherry tree worth mentioning. Few "nut" trees are ripe at the start of Aug. and a feller has to know about other food sources in order to find many squirrels.
I am going to post a link (hopefully) to a pretty good looking site that has pictures and descriptions of the various types of trees and shrubs we will be discussing. It will make identifying easier...if it works!
https://tree.oplin.org/tree/cherryblack
On the southernmost quarter of Illinois, the Tulip tree (yellow poplar) can be found. This tree is enormous as eastern trees go. It is commonly over 100 Ft!
I will leave the description go. You can read about the tree itself in the following link.
https://tree.oplin.org/tree/tuliptree
The leaves are large and dense in the crown. A squirrel in the middle of the tree may as well be under a mountain! He is pretty safe there.
I have found squirrels eating the fruit (seedpod) on the first day of August. They obviously start on them earlier than that. I have found them still eating the pods in November. If you look at the picture of the seedpod in the link, you will notice the pod is sort of Christmas tree shaped. Each individual blade on the larger end contains a small seed kernel that the squirrels eat. That's the only part they eat in august. They usually just eat around the large end and as they do the individual blades that the seed is attached to get cut loose and flutter to the ground. There is no noise much when they do hit the ground. The only noise is when the squirrel is out on the end of a limb looking for seedpods and when he gets done with one and drops the core.
The tip that squirrels are up in a tulip tree is the endless amount of the little blades fluttering downward. I know of nothing else that uses the seedpods in the unripe state.
Hunting squirrels in Tulip trees can be a miserable experience. There can be a lot of them up there and you will be lucky to get ANY of them. The only time you actually see them is when they are out on the end of a limb getting a fresh pod and they don't stay there but a few seconds. After the leaves come off, it's a bunch easier but at that time there is usually an abundance of other foods that the squirrels seem to prefer.
I reckon the problem with tulip trees is that you have to stand right under one to see up in it much. I don't care how old you are, you are going to endure a lot of pain in the neck to get ANY squirrels out of a Tulip tree.
Crow feather mentioned laying on his back while waiting and I admit to doing just that. It probably is a more natural shooting position than trying to shoot straight up while standing!
Some things that squirrels eat are just not as illustrious as others! Almost nobody talks about squirrels in honey locust trees. It seems that it would take a squirrel of great daring to make a jump into a honey locust tree!
https://tree.oplin.org/tree/honeylocust
The tree is covered top to bottom in the most wicked looking thorns I ever laid eyes on! They grow all up and down the trunk and are REALLY long and branched even! It's a good idea to wear hard bottom shoes in honey locust timber.
First off, let me say that I have never seen a gray squirrel up in a honey locust tree. They may go up there...I have not seen it. It's those REALLY BIG fox squirrels that I see in them. We are talking 3 pound plus fox squirrels and tough as a boot.
The honey locust isn't a bad looking tree. They have a long, flat seed pod that hangs from its branches. These look like a really long green bean!
Anyways, those old fox squirrels risk it all for the "beans" in this pod. I am not sure how long they might use this food source or how often but I found them eating them in the first part of August.
I must say that when I did find them in honey locust trees, the woods that contained them was usually not much of a squirrel woods in the first place.
Hunting in this type of woods is where I found squirrels eating some of the more uncommon and unsavory types of foods. There was little variety and they ate what was available at the time.
Haws are another type of squirrel food that one does not hear of often. I have found squirrels in Hawthorne trees in early August. The haw is another of those trees that is full of nasty looking stickers. Big stickers too.
https://tree.oplin.org/tree/hawthorn
I found the Haws growing in the same place as the Honey Locust. It was a plumb stickery woods!
Again, I have only seen fox squirrels up a Haw tree, but the woods I found the Haws in only had fox squirrels in it. Most of the trees I have seen occurred in the understory and were not much more than shrubs.
The Haws I have run into in the woods were both black and red.
The Osage orange (Hedge apple or hedge tree as Sarge called it) is another of the foods eaten by squirrels. I should say that, again. Fox squirrels are the only squirrel I have ever seen eating them.
https://tree.oplin.org/tree/osageorange
There are a great many Osage orange trees in Illinois and especially through the central part of it.
This is the tree famous for the wood that is used to make bows.
I have found the fox squirrels eating the hedge apples in the first part of Aug. It was comical to watch a fox squirrel wrestle one of those big ole apples into a fork in a tree and wedge it there so he could work on it in a more serious manner!
There is a catch with squirrels eating hedge apples. After a short time, the squirrel gets a strong smell and taste to them. You can smell it when you skin them. I never relished eating squirrel that had spent any time in the hedge apple trees.
The hackberry tree is another of the foods squirrels use that is little talked about. Over the years I have found both kinds of squirrels in hackberry trees in the early part of Aug.
https://tree.oplin.org/tree/hackberry
Like the black cherry, there are other critters that can be up a hackberry tree in pursuit of its fruits. At least the berry makes a little noise when they are dropped from the tree and you may hear some stray ones hitting the ground.
I have found the hop hornbeam growing in the southern part of Illinois. I also found both kind of squirrels eating the little nutlets inside the little capsules in the first part of august and onward.
https://tree.oplin.org/tree/easternhophornbeam
I am always amazed when squirrels show interest in something so small. Of course, they make no noise at all in the process of eating them but only in searching the tree for them. Maybe they taste like Hagen Das ice cream to them....who knows???
The last non-nut type tree of interest is the Cucumber Tree. I have stumbled across a few of these in my wanderings through the Shawnee forest.
https://tree.oplin.org/tree/cucumbertree
It was always in the early parts of Aug. when I found squirrels using them. As they were deep in the middle of the forest, all I ever saw using them was gray squirrels.
Most of the foods we have learned about so far make little or no noise when the squirrel eats them.
Toward the end of Aug. there becomes an abundance of hard shelled nuts that ripen. Those are what most squirrel hunters LONG for. Those are the next topic of interest!
The 3rd week of Aug. in Illinois, it is common to start seeing signs of squirrels sampling hickory nuts. Some years, they may be hard at them by then.
Some years, the whole crop of hickory nuts fail for some reason. It's enough to make hardnosed squirrel hunters boo-hoo in their cornflakes! To go a whole season without finding squirrels in the hickories is a big disappointment!
There are 5 kinds of hickories in Illinois. All five kinds are found in the Shawnee forest.
In my experience, squirrels will start on 4 of them sometime in late Aug. By mid- September, they are hard into all of them.
The Shagbark (Scale bark) is the most recognizable of them all.
https://tree.oplin.org/tree/hickoryshagbark
The bark makes it easy to spot. The nuts can be quite large and this keeps the squacks busy in one spot for a spell which gives you time to slip up on em! There will be a LOT OF NOISE associated with a squirrel cutting hickories. You will hear the "grit...grit (Sarge's description) of the teeth on the hard shell. You will also hear the outer husks hitting the ground and the steady pitter patter of the smaller cuttings falling through the leaves. Their nails on the loose bark and limbs swishing around as they search the tree are other noises you will hear.
The next three hickories you may or may not have seen or heard of!
https://tree.oplin.org/tree/hickorypignut
https://tree.oplin.org/tree/hickorymockernut
https://tree.oplin.org/tree/hickorybitternut
I know I have taken squirrels in the Pignut and Mockernut hickories. They make the same noises eating them and really there is no reason to be able to tell one from the other than to be able to find more of the same tree elsewhere. They may prefer different habitats.
The last hickory is important to me. In years where all of the preceding hickories fail, I have seen Shellbark Hickory produce massive amounts of mast. They rarely fail completely. It seems that they wait until about late-September to go at them in a big way.
https://tree.oplin.org/tree/hickoryshellbark
They like high ridge tops too. There are ridges in Shawnee that are just lined in Shellbark trees.
One great thing about finding squirrels eating hickories is that nothing else I know of eats them! Not up a tree anyways. If you hear cuttings falling out you can be almost positive ...there be squacks up in there!
For you folks who have no squirrel season when the hickories are ready...I feel for you! You are missing it! A tree with 10 or eleven squirrels in it raining hickory cuttings will get the blood pressure up!
A lot of years ago (when I was a young buck) I hunted a creek bottom close to home. On the banks of the little creek stood a lone specimen of Horse Chestnut (Buckeye).
https://tree.oplin.org/tree/horsechestnut
Over the few years I hunted there I found fox squirrels eating those buckeyes. In all the hunting I have done since, I cannot tell you that I have ever seen a squirrel eating buckeyes since.
If my memory serves me correctly, I found them using them around the same time as they were at the hickories. I only mention this for the record.
If any of you have found squirrels eating buckeye, I would like to hear about it.
As the Sarge has mentioned, I have found squirrels eating fox grapes. Fox grapes don't qualify as a tree but squirrels do use them as they ripen...if they ever do. If there is something more sour than a fox grape, I don't want any!
Gobs and gobs of acorns!
I have read that in the Shawnee forest, there are over 30 types of oak trees! I wish I could identify MOST of them. I can't.
The earliest I see squirrels in Oak around me is in the first part of August. I find it amazing that the swamp oak in my yard is ready by then as it does not even have leaves on it until the end of May.
Oaks vary greatly in size and location. I will only touch on a couple of them and leave the rest for you all to study up on. The only reason I mention these two kinds is because of the great difference between them.
The first is the shingle oak. It is the only oak I know of that does not have the familiar oak leaves. Look at them closely. The acorns are really small as well. I have taken squirrels while they were eating them though.
https://tree.oplin.org/tree/oakshingle
This is another nut that would not normally seem worthwhile for a squirrel to mess with. The ones I am familiar with rarely got to a half of an inch (.500) in dia.
The other is just the exact opposite. The burr oak can have some HUGE ACORNS! The variety I am thinking of, we use to call Over Cup acorns.
https://tree.oplin.org/tree/oakbur
Those nuts can be around 2 inches in diameter! That's a lot of dinner for a little bushy tail!
We are not going to talk about acorns a bunch. They are probably responsible for the biggest mast crops most years and assuredly must do a lot towards keeping a large populations of squirrels well fed. They also feed a lot of other critters as well.
You will find them growing in swampy ground (pin oak) and on top of the highest dry ridges. They have lots of holes and are regular den trees.
Acorns are easy for young squirrels to eat as they have a softer shell. They make the usual noise looking for them in the trees. A hunter can usually hear the caps and cuttings hitting the forest floor. On some occasions, I am able to hear a little of the grit-grit of squirrel teeth on a nutshell, but, not often. It's the other sounds that normally give them away.
As there are other critters that eat acorns and knock them out, one never really knows, from whole nuts falling, what is up an acorn tree. You will find chipmunks, ***** and all the birds in the woods up in there. That's why hickory nuts are special! There is no doubt what's up there!
As a general rule, you may find squirrels eating acorns anytime from late august onward. They pack a lot of them around after the nuts fall to the ground. A squirrel just can't stand for a bunch of nuts to be laying all over the top of the ground. It's his bound duty to bury them all! That's why in fall, after the leaves and nuts go down, that's where you will find him. Rustling the deep leaves under those big old oak trees!
One of my favorite trees to find squirrels in is the beech! Around mid-September they become ready.
https://tree.oplin.org/tree/beech
The beech is as fine a specimen of squirrel wood as there is in my opinion. The smooth greenish gray bark is the key to quickly identifying it. The trunk of an old specimen is normally full of enough holes for an army of squirrels to live in. The tree can produce an enormous crop of beechnuts too.
A squirrel’s love of beech is something to see. Each little burr contains 2 pyramid shaped seeds. The seeds are fairly soft and pithy. It is another food that is ideal for young squirrels as it is easy for them to get at.
I believe that every bird in the woods just sits around waiting for the beech to ripen. You will find them up there as well.
It can be tough to get squirrels in beech, at times, with a rifle. The squirrels seldom sit long eating them. They are all over the tree, eating as they go. A beech can be huge. Sometimes, you can only see the tree from right beneath it.
The beech usually grows around the bottom of deep draws and up the sides of it. The biggest specimens are usually close to the bottom of the creek. With a rifle, one can sometimes get above the treetop by climbing the sides of a ridge. It seems easier to spot the squirrels from above, if you can get there.
Believe me when I say, there can at times be a heap of squacks up a beech tree. Years ago while hunting with a shotgun, I sometimes would drop several from one tree. After all the racket died away, I would be amazed that the cuttings would still be raining out of there! I have also had the same experience hunting in the peak of the hickory season. At times, the squirrels just would not quit! The beechnuts usually hang on the trees until mid-October...if the squirrels don't eat them all!
Turkeys, deer and bear also feed on the beechnuts. Some years it can cover the ground under it with nuts.
I have personally seen beech as far north as Wisconsin, Michigan and New York.
In some parts of western Wisconsin, the make-up of a woodlot can be predominately black walnut. This tree can be found all across Illinois as well. Squirrels in Illinois normally start on walnuts in mid to late September. This can change to drastically earlier in some years.
https://tree.oplin.org/tree/walnutblack
This is another great nut tree for squirrels! You can hear the grit-grit noise of squirrels cutting walnuts a long ways off! There is a pile of racket associated with squirrels cutting the nuts. Both fox and gray squirrels are quite fond of the walnut.
The walnut tree foliage is more open than a lot of the other trees. Their leaves are some of the first to fall as well. The nuts will hang on longer than the leaves.
When the leaves are gone or mostly so, the squirrels get nervous sitting in the bare tree. When you hear one cutting and get the walnut tree singled out you think he is in, look first at the junction of the trunk and the limbs. It can usually be found down low with his butt against the trunk. They may feel safer there as they can dodge behind the trunk to avoid predation by hawks.
The squirrel may also be sitting in the brush down low to the ground. Late in the fall you can sometimes find a spot in the brush with large piles of walnut cuttings in one spot. This is surely a spot where the squirrel feels safer. It takes a squirrel quite a while to eat a walnut and in the open, it is vulnerable.
If squirrels are hunted much in the walnut season, they can become quite "cagey" when cutting them. They can cut so softly that you will have a hard time locating them. When they are doing this, they have usually seen you but have not become alarmed enough to "run for it".
I should also mention the butternut at this time. It looks similar to the walnut but is oblong shaped.
https://tree.oplin.org/tree/butternut
I have run into a FEW butternut trees here and there. I never saw a bunch of them anywhere! Squirrels like them. I mention them only so you will see the difference in the nuts, if you ever run up on them.
Squirrel hunting in walnut timber is what the rimfire rifle shines at! The old squack, once he starts on a walnut, is not going to be moving around for a while. You can really take your time and "squeeze down" on em! I have made my "most memorable shots" after the leaves come down in the walnut timber. You can sometimes spot them a long ways off if you know what to look for!
The pecan is found on the southernmost end of Illinois and becomes ready about the same time as beech and walnuts. In Illinois, these are found in rich bottoms. The nut is much smaller than the ones grown commercially. This tree is not abundant but I have found them in small numbers in Illinois.
https://www.hunker.com/13404768/pecan-tree-identification
They still taste the same! Both kinds of squirrels like them and use them. They make the same kind of noises looking for the nuts and eating them.
With the ripening of pecans, walnuts and beech all of the nut bearing trees I know of have now ripened for the season. Usually by late October, the majority have fallen to the ground.
When the nuts and leaves have fallen, squirrels spend a lot of their time on the ground packing and burying nuts of all kinds.
With the nuts on the ground, we will skip ahead to the spring period and talk of the trees that squirrels find food in at that time. Once we cover the entire season, we will get into squirrel hunting proper!
Illinois does not have a spring squirrel season. Shucks!
Squirrel hunters can learn a lot about squirrel hunting by observing their activities year around.
The critters usually start breeding here in late December or early January. I see the first litter out and about around April.
As I have mentioned before, when certain foods become available will depend on the latitude in which you live.
In this installment, I will cover the basic spring foods that squirrels find in trees around here in the spring. These trees may be found in your area but may be done by the time the spring seasons come in.
The first thing I see squirrels eat is the leaf buds from most of the soft wood trees before they leaf out. Mostly, soft wood trees leaf out first.
Before the leaves of some trees appear, they may put on some types of seed. One of these is the maple. There are many varieties of maple but most of you are familiar with the winged (helicopter like) seeds they produce.
https://tree.oplin.org/tree/maplesilver
I have squirrels eating these seeds in my yard at this time. They eat a lot of them....I wish they would eat them all!
The next is the elm tree. Morel mushroom hunters love elm trees! Anyways, what a squirrel sees in an elm seed is a mystery to me. They are so small that it seems a waste of energy eating them....but they do.
https://tree.oplin.org/tree/elmslippery
I said that I would stick to the trees that I know about personally and so must leave some of the trees out. Anybody who knows of other spring trees that squirrels use are welcomed to post them.
In my yard, in late June, the mulberry fruits here. Birds and squirrels can be found in them eating all the mulberries they can hold.
https://tree.oplin.org/tree/mulberryred
Lots of young squirrels can be found in mulberry trees when they are ripe.
Later on in summer, I have found squirrels eating apples of all kinds. Here in my area, there are a great many wild apple trees in the woods. Squirrels do use them on occasion.
Of course I can't keep the buggers off my bird feeders! That's where most city folk get the mistaken idea that all squirrels act like birdfeeder squirrels. Make no mistake about it....they don't.
If you hunt a woods that has no squirrel hunting pressure at all and only hunt it once or twice a year....it will be pretty easy to get a limit of squirrels.
If you hunt where squirrels are hunted pretty hard...they can be amazingly tough to come by. Don't count on them being a cinch!
We are going to leave the trees at this point and focus on squirrel hunting tactics and strategies! Now that we know what squirrels like to eat and when to expect them to start eating it, we can make a plan before we get to the woods. This means knowing the woods that you hunt pretty good and how to identify the trees that squirrels use.
