The short answer
What Audubon Certified Bird Friendly Means.
Audubon Certified Bird Friendly is a certification from the National Audubon Society for ranches that manage their land as habitat for birds. To carry the seal, a ranch follows a habitat plan written for its own ground and grazes cattle on open grassland with no feedlots. It uses no hormones, antibiotics or pesticides and protects its streams. An independent third party audits all of it.
- No feedlots
- No hormones
- No antibiotics
- Independently audited
What it means for you
Cattle on open grassland, never a feedlot
- No growth hormones. No animal that has had antibiotics is sold under the seal.
- Pesticides and neonicotinoids banned outright.
- Checked by an independent third party, not just promised on a label.
What it means for the land
Grassland managed for the birds that need it most
- Native grass left tall enough to nest in, and rested between grazings.
- Insects, wildflowers and pollinators left alone to feed the birds.
- Streams protected from runoff, with grass cover holding the soil.

Why Audubon Partners With Ranchers.
Audubon works with ranchers because it's the last grassland bird habitat still intact across the American prairie.

Near Threatened, and on our ground
Most Oklahomans Last Heard a Bobwhite as Kids. They Still Call the Double P Ranch home.
All three are grassland birds in decline across their range. The bobwhite and meadowlark nest on the ground here; the Bobolink stops over on its way north. They need tall native grass left standing and insects to eat. Sprayed, overgrazed pasture has neither.

Why birds
North America Has Lost More Than Half Its Grassland Birds Since 1970.
Grassland birds have fallen further than the birds of any other habitat on the continent. Most of the prairie they nest in has been plowed under or sprayed, and the insects they feed their young went with it.
That's why a bird count is such an honest test of a ranch. If the grass and the insects are healthy, the birds show up. A healthy bird population is one of the best signs of a healthy farm.
of North America's grassland birds, gone in one lifetime.
Still here, of every 100 in 1970Lost since 1970
Audubon Certified land reverses the decline.
Audubon scientists survey birds on certified ranches and score each one on a Bird-Friendliness Index, a measure of the birds certified land supports compared with conventional land next door. Between 2016 and 2023, the index on certified land rose 76%, more than 8% a year.

From the grass to your plate
The Same Grass Feeds the Birds and Your Beef.
Insecticide kills the insects birds feed on. Herbicide kills the native bunch grass they nest in. We'll take a few thistles and grasshoppers over a pasture soaked in chemicals any day, because that grass is what our cattle eat too.
What the land grows
01 · Soil
Living soil
Roots, fungi and dung beetles, kept alive by grazing and rest instead of tillage and spray.
02 · Grass
Native grass and forbs
Big bluestem, switchgrass, milkweed and wildflowers, dozens of plants in one pasture.
03 · Insects
Crickets and flies
The protein every baby chick is raised on.
04 · Birds
45+ species
Meadowlarks in the grass, bluebirds on the fence, hawks overhead.
What that means for you
01 · Soil
The same ground
No feedlot. The cattle spend their whole lives on this land.
02 · Grass
A varied diet
Cattle graze a mix of grasses and forbs, then move so the pasture can recover.
03 · Cattle
Finished on grass
Pasture and forage for life, finished on grass. What they eat at the end is what sets the fat in the meat.
04 · Your beef
2:1 omega-6 to omega-3
Conventional grain-fed beef runs about 15:1. See the lab results
What the seal requires
The Rules, Next to What Commodity Beef Is Allowed to Do.

Where the birds live · American land
Three Ecosystems Meet on Our Ranch.
Our ranch sits in the Cross Timbers ecoregion, the belt of oaks where the tallgrass prairie, oak savanna and woodlands converge. That's how one morning's count turned up a meadowlark in the grass, an oriole in the oaks and a Barred Owl in the woods.

It's all American ground. Every farm in our program is a working American farm or ranch, and nothing we sell is imported. Ever.
“Birds and beef are connected on the ground.”
Prairie birds are a passion of ours. The best part is, improving their populations doesn't amount to a choice between economics and environmental stewardship. Birds and beef are connected on the ground, fitting right in with our regenerative grazing methods.

Bird Friendly Beef, Answered.
What does Audubon Certified Bird Friendly mean?
It is a certification from the National Audubon Society's Conservation Ranching program for farms and ranches that manage their grazing land as habitat for birds. A certified ranch follows a habitat management plan written for its own land and grazes livestock on open grassland with no feedlots. It uses no hormones and sells no animal that has had antibiotics. It restricts pesticides, bans neonicotinoids, protects waterways, and is audited by an independent third party.
Are all REP Provisions farms Audubon Certified?
Every farm and ranch in the REP Provisions beef program is Audubon Certified Bird Friendly. Our home ranch in Mounds, Oklahoma, was certified in February 2021.
Is Audubon Certified beef grass-fed?
Audubon requires cattle to graze freely on open grassland and bans feedlots. It keeps grain supplementation to a minimum rather than banning it outright. REP beef goes further: our cattle eat pasture and forage for life and are finished on grass, never in a feedlot.
Does bird friendly beef make a difference to my health?
The seal rules out the things many people are trying to avoid: feedlots, growth hormones, antibiotics and animal byproducts in feed. We test the nutrition separately. In independent Edacious lab testing, REP beef measured about 2 parts omega-6 to 1 part omega-3, where conventional grain-fed beef runs about 15 to 1. The full results are published on our lab results page.
How many bird species live on the REP ranch?
In 2026 Jacob Yetter, Conservation Ranching manager for the National Audubon Society in Kansas and Oklahoma, counted more than 45 bird species on our ranch in under two hours. He called it the most bird species he had seen on any ranch he had visited. Three of them, the Northern Bobwhite, Eastern Meadowlark and Bobolink, are listed as Near Threatened on the IUCN Red List.
Why are grassland birds declining?
North America lost 53 percent of its grassland birds between 1970 and 2017, a steeper loss than the birds of any other breeding habitat (Rosenberg et al., Science, 2019). The main causes are native grassland being plowed or developed, and insecticides and herbicides that remove the insects birds eat and the native grass they nest in. On Audubon Certified land, Audubon's Bird-Friendliness Index rose 76 percent between 2016 and 2023.
Where is the REP Provisions ranch?
Our ranch is in Mounds, Oklahoma, in the Cross Timbers ecoregion, where tallgrass prairie, oak savanna and woodland meet. Orders ship from our warehouse in Bixby, Oklahoma. Every farm in our program is American, and nothing we sell is imported.
Who checks that a ranch meets the Audubon standards?
Ranches are audited against the Audubon Conservation Ranching standards by an independent third party, Food Alliance. The standards are published by the National Audubon Society.

You Can’t Fake a Meadowlark.
Birds only stay where the grass, the insects and the water are healthy. Forty-five species stayed on ours. Your beef comes from the same ground.
