What Do Deer Eat?

These herbivores have a diverse diet, and their eating habits depend on the season, their geographical location, and the availability of food. In this article, we will explore what deer eat, their favorite treats, and what they eat in the wild.

As deer farmers, we can answer your questions on what food is safe to feed to the deer.

What do deer normally eat? 

Generally, when it comes to what plants do deer eat in the wild, deer are pretty much down for plant-based anything. And by "anything," I mean anything - just ask any gardener who's had their carefully cultivated plants reduced to nubs by these voracious herbivores. If you're a gardener, you know the struggle is real. Those 🦌🦌 are more than happy to nibble on your prize-winning roses, your fresh veggies, and pretty much anything else you've got growing. It's like they're thinking, "Oh, what's that? Looks tasty. nibble nibble Oh, and that too? nibble nibble Don't mind if I do."

Here are some of the main categories of food that deer normally eat:

1. Leaves and shoots: Deer browse on the leaves and shoots of trees and shrubs, including maple, oak, willow, and dogwood.
2. Grasses: Deer feed on a variety of grasses, including tall prairie grasses, bluegrass, and fescue.
3. Twigs and branches: In the winter, when other food sources are scarce, deer will strip the bark from twigs and small branches to access the inner layer of the tree.
4. Nuts and acorns: Deer love to eat nuts and acorns, including those from oak, hickory, and beech trees.
5. Fruits and berries: Apples, pears, blackberries, and blueberries are just a few of the fruits and berries that deer enjoy.
6. Legumes: Deer will graze on legumes such as clover, alfalfa, and soybeans.
7. Forbs and wildflowers: Forbs are non-woody plants that are typically found in open fields or meadows. Deer will eat a variety of forbs and wildflowers, including dandelions, goldenrod, and asters.

Overall, deer are opportunistic eaters and will consume whatever plant-based foods are available to them depending on the season and their geographical location. A muntjac deer, for example, can eat up to 85 different types of plants [source].

According to Mississippi State University, white-tailed deer's salivary glands produce enzymes that help deactivate secondary plant compounds, (tannins), that disrupt digestion. These enzymes allow them to eat a quantity of acorns that would kill a cow.

What do deer eat in the summer?

In the summer, deer have a diverse range of food options available to them.

They typically feed on plants including clover, wildflowers, corn, soybeans, rye, alfalfa, berries, legumes and a whole bunch more. But you know what else they like to munch on? Apples, crab apples, plum bushes, and even some shrooms. Basically, if it's within reach, they'll probably give it a taste.

What do deer eat in winter?

Food is significantly harder to find in winter, so deer become reliant on buds, saplings, woody plants, including evergreens, bark and dried leaves.

That's not much and wild deer do lose weight in winter, up to 30% of their body mass, that's why they try to gain as much as possible in warmer months.

If the herd is lucky to be in the area where unsuspecting farmers have planted their crops, they will also invite themselves to feast on agricultural crops like wheat, rye, or soybeans.

According to the Department of Environmental Conservation, based on thousands of observations from deer wintering areas in New York State, winter deer food favorites are:

• cedar (white or arborvitae)
• sassafras, wintergreen
• alternate-leaved dogwood
• yew
• mountain maple
• witch hobble
• basswood
• apple
• maples
• flowering dogwood
• staghorn sumac.

What do deer like to eat the most?

One question if what deer can eat and another - what they prefer if they have a choice. What treats do deer like to eat?

Deer love to eat berries, acorns, nuts, corn, fruits like bananas, peaches and pears, carrots and bread. A lot of their favorite picks you'll find in the list below. All such yummies come with a warning though, while feeding tree branches or oats is totaly safe, basically anything deer wouldn't normally find in the woods - isn't safe in big quantities. Please see considerations about feeding deer.

Do deer eat meat, small animals?

Deer are mainly all about that veggie life, but every once in a while they go rogue and get a little meaty. I mean, we're talking super rare occasions here, usually when they're feeling pretty desperate for a snack. It's been known to happen that a deer might chow down on a bird, rodent, or even a fish - but that's not exactly their go-to meal. I guess you could say they're not really big fans of the whole "meat and greet" thing. We have a post dedicated to this question titled Are Deer Herbivores, Omnivores or Carnivores. 

Should you feed wild deer?

If you've landed here searching for «what do deer like to eat», you're likely thinking of feeding deer in your backyard. In that case, keep in mind that depending on where you live it may be illegal for you to do that.

Winter is a challenging time for deer, and a nature's way of culling the weaker herd members. (( As heartbreaking as that may be, supplemental feeding of them presents its own set of problems and according to many reputable sources can do more harm than good. Such as:

• introducing improper food. Corn, bread will be eaten by deer but can kill them. Small amounts are fine, but if one leaves a bunch of it and only one or a couple of animals find it and eat the whole lot they can die from indigestion. With wild deer not approaching it until you leave, you can't control how much any one of them will consume.
• by attracting the deer into one spot people cause them to congregate in large groups, and that can lead to increase in communicable disease spread, like CWD (not present in NZ). Everybody knows what social distancing is these days and the merits of it. Well, by promoting concentration of deer people are endangering their health.
• it's hardly sustainable long-term, as deer will habituate the feeding spot and eventually hang out there most of the time, stripping any and all vegetation present in the area, destroying trees by eating bark and rubbing antlers on them.

  Where a few deer are today 🦌🦌 tomorrow can be a hundred 🦌🦌🦌🦌🦌🦌 In deer world 'the word travels fast'. So more animals will burn their precious fat deposits hoping to come and dine at your sites. If they then arrive to an empty spot or there's only enough to feed half of them you may have made a bad situation worse;

  Even if you succeed in saving more deer one winter through supplemental feeding, overpopulation of these animals does not benefit them in the end. Since you stop supplement feeding in spring, they're on their own but in bigger numbers than vegetation in the area can sustain. There will also be detrimental effect on the birds whose habitats deer eat away.

• concentrating deer near inhabited areas may result in increased traffic accidents;
• attracting deer near peoples' property through feeding can also attract predators, like cougars or coyotes. Also, deer can under certain conditions be aggressive themselves and are capable of causing serious injuries to humans;

If you want to help deer survive winter:

You can do this by creating and maintaining good quality deer habitat and improving food resources that will actually benefit all wildlife.

• plant mast producing trees and shrubs, and protect those plantings until they are large enough to survive deer browsing;
• plant evergreen trees for winter thermal cover
• cut sections of mature forests to create forest openings and increase the amount of woody browse available to deer. Read Cutting Browse for Deer.

If you can't resist feeding deer, follow these guidelines:

• To promote better dispersal of animals feed in several sites;
• To avoid human/wildlife conflicts feed well away from any roads or peoples houses;
• If you begin feeding in fall, continue until snow melt in spring, as deer can become dependent on you. Prepare to give more feed as more deer will discover and frequent your sites;
• Spread the food really well, so numerous deer can have simultaneous access to it without fighting. Stronger bucks will often hoard the best spots for themselves and kick approaching competition. So instead of dumping all in one spot make thin, long lines of food, they can go parallel, as long as there's enough room between them for animals to stand. The wider you can make the area the better.

You can search through this following list of foods to see if deer might enjoy it [to be continued]:

Do deer eat berries?

🦌: "Oh deer god, please send us some!"

Berries of all kinds are deers favorite food. Strawberries, blueberries, blackberries, grapes , watermelon - all are highly appreciated by these gourmets. Berries are packed with minerals and vitamins, acids and sugar and so are perfectly fitted as deer feed. Not that you'd want to share a lot with them, would you? Still, it appears that berries are deer's favorite treat. Absent that, deers' sweet tooth is leading them to fruits. Pears, peaches, apples,  bananas.

Can deer eat corn?

Deer: "Would sell our souls for it!"

Deer love maize, but it presents danger when consumed in big quantities by animals not accustomed to it.

Will deer eat dog food?

🦌: "You gotta be kidding me!"

Seriously, dogs are omnivores (evolved from carnivores), even the cheapest dog food contains (hopefully, for dogs sake) some meat. You shouldn't try and feed herbivores meat products.
