Texas wanted to kill 1.5 million bats – now they bring in $10 million a year

Congress Avenue Bridge’s Accidental Bat Colony Transformation

In 1980, Austin’s Congress Avenue Bridge got a new look but gained some odd guests. TxDOT engineer Mark Bloschock built it with concrete beams spaced just right for bats to move in.

Soon after, 1. 5 million Mexican free-tailed bats made it home.

Locals went wild with fear, and papers ran scary headlines. Then came Merlin Tuttle in 1986, a bat expert who moved from Milwaukee to save them.

He even kept a tiny bat in his pocket to win folks over. Now, those same bats bring 140,000 tourists and $10 million yearly to Austin.

The story of how a feared pest became a city treasure awaits at South Congress.

Engineers Accidentally Built the Perfect Bat Hotel in 1980

Heavy rains washed out the road to Congress Avenue Bridge in August 1978, forcing it to close. TxDOT spent over $5 million fixing and widening it with concrete box beams.

Engineer Mark Bloschock’s team put these beams about an inch apart, making gaps 16 to 18 inches deep. No one knew they had built a perfect bat home.

The bridge opened again in April 1980 with its bat-friendly design hidden under the road.

Thousands of Mexican Free-Tailed Bats Found Their Dream Home

After the bridge reopened, hundreds of thousands of Mexican free-tailed bats started living in the bridge cracks.

These small animals quickly found that the narrow gaps gave them dark, warm shelter for sleeping and raising babies. The sun warmed the road above, and this heat moved down into the gaps, making them cozy.

The colony grew fast as more bats told others about this great spot in downtown Austin.

Headlines Screamed About a Bat Invasion Taking Over Austin

In September 1984, the Austin American-Statesman ran the headline “Bats Sink Teeth Into City. ” Another paper warned “Mass Fear in the Air as Bats Invade City.”

Health workers told people that thousands of rabid bats lived under the bridge and attacked locals. Many scared folks signed papers asking the city to get rid of the bats.

People saw the colony as a health threat rather than something special.

Bat Expert Moved His Tiny Organization to Austin to Face the Crisis

Bat expert Merlin Tuttle worked at Milwaukee Public Museum when Austin made national news. In March 1986, Tuttle quit his job to move Bat Conservation International to Austin.

His group had only a few hundred members and less than $10,000 when he came to Texas. Friends thought Tuttle was crazy for taking such a risk, but he saw the fight as a chance to change minds.

Tuttle Started Changing Minds One Person at a Time

Merlin used a plan he called “winning friends not battles” to change what people thought. He talked with Austin city workers, health staff, and news folks to explain bat benefits.

Tuttle shared facts about how bats eat tons of bugs nightly and carry less rabies than dogs.

He often kept a tiny Mexican free-tailed bat in his pocket during meetings to show how cute and safe these animals really were.

Texas Monthly Gave Tuttle Their “Fool of the Year” Award

Texas Monthly gave Tuttle the 1986 Bum Steer Award for his work. This joke award, given for mistakes and silly efforts, showed how many people doubted him.

Austin mayor Frank Cooksey recalled how folks linked bats with vampires, making them scared. News outlets kept running scary stories about rabid bat attacks.

Most Austin people still wanted nothing to do with their new neighbors.

The Bridge Designer Became an Unlikely Bat Ally

Tuttle teamed up with TxDOT engineer Mark Bloschock who built the Congress Avenue Bridge. They studied why bridges drew cave bats so strongly.

Their work found no proof that bat groups harmed concrete bridges despite what officials feared. They learned that beams placed about an inch apart made fake caves with sun-warmed roofs, perfect for bat homes.

Bloschock became a key helper in the fight to save the bats.

Facts About Bats Started to Replace Fiction and Fear

Tuttle kept talking with community leaders, health staff and news people, and it slowly worked. He used easy-to-remember facts about how bats eat bugs and rarely spread sickness.

Bloschock praised Tuttle’s “brilliant, non-confrontational environmentalism” that taught without fighting. People slowly began to see that bats made safe and helpful neighbors.

Science took the place of old fears as more folks learned about bat life.

Sunset Bat Flights Became a Must-See Austin Attraction

Congress Avenue Bridge bats quickly turned into a tourist draw bringing money to local shops. Nightly flights of bats over Lady Bird Lake pulled crowds to watch the show.

Austin started talking up the bat colony as a cool learning spot everyone should see. Local stores printed bat t-shirts and used bats as a city symbol.

Tour boats started offering sunset trips to view the bats from the water.

The World’s Largest Urban Bat Colony Settled in Downtown

Peak season brings about 1. 5 million Mexican free-tailed bats to Congress Avenue Bridge.

Female bats raise roughly 750,000 babies each year in this maternity colony. Bat Conservation International calls it the world’s largest city bat group.

The bats come from Mexico each spring, stay through fall, then go south for winter. Their nightly bug eating helps local farmers by naturally killing crop pests.

Austin Proudly Calls Itself the “Bat Capital of America”

Bat tourism brings 140,000 visitors to Austin annually according to Texas Parks and Wildlife. These visitors generate approximately $10 million in local revenue each year.

Austin proudly adopted the title “Bat Capital of America” celebrating the colony that once terrified residents. TxDOT even started a research program with biologists to make other Texas bridges more bat-friendly.

The accidental bat habitat created in 1980 transformed from public health crisis to beloved city icon.

Visiting South Congress Avenue, Texas

You can watch the famous bat colony emerge from Congress Avenue Bridge at 100 South Congress Avenue for free from the sidewalks or Austin American-Statesman’s Bat Observation Center.

The 1.5 million Mexican free-tailed bats fly out 30-60 minutes before sunset from mid-March through early November. Volunteer educators answer questions on weekend evenings May through September.

You can also take boat tours with Lone Star Riverboat or Capital Cruises, or attend the annual September Bat Fest with music and activities.
