Newborn rattlesnakes at a Colorado 'mega den' are making their live debut
CHEYENNE, Wyo. (AP) — A “mega den” of hundreds of rattlesnakes in Colorado is getting even bigger now that late summer is here and babies are being born.
Thanks to livestream video, scientists studying the den on a craggy hillside in Colorado are learning more about these enigmatic — and often misunderstood — reptiles. They’re observing as the youngsters, called pups, slither over and between adult females on lichen-encrusted rocks.
The public can watch too on the Project RattleCam website and help with important work including how to tell the snakes apart. Since researchers put their remote camera online in May, several snakes have become known in a chatroom and to scientists by names including “Woodstock,” “Thea” and “Agent 008.”
The project is a collaboration between California Polytechnic State University in San Luis Obispo, snake removal company Central Coast Snake Services and Dickinson College in Carlisle, Pennsylvania.
By involving the public, the scientists hope to dispel the idea that rattlesnakes are usually fierce and dangerous. In fact, experts say they rarely bite unless threatened or provoked and often are just the opposite.
Rattlesnakes are not only among the few reptiles that care for their young. They even care for the young of others. The adults protect and lend body heat to pups from birth until they enter hibernation in mid-autumn, said Max Roberts, a CalPoly graduate student researcher.
“We regularly see what we like to call ‘babysitting,’ pregnant females that we can visibly see have not given birth, yet are kind of guarding the newborn snakes,” Roberts said Wednesday.
As many as 2,000 rattlesnakes spend the winter at the location on private land, which the researchers are keeping secret to discourage trespassers. Once the weather warms, only pregnant females remain while the others disperse to nearby territory.
This year, the scientists keeping watch over the Colorado site have observed the rattlesnakes coil up and catch water to drink from the cups formed by their bodies. They’ve also seen how the snakes react to birds swooping in to try to grab a scaly meal.
The highlight of summer is in late August and early September when the rattlesnakes give birth over a roughly two-week period.
“As soon as they’re born, they know how to move into the sun or into the shade to regulate their body temperature,” Roberts said.
There are 36 species of rattlesnakes, most of which inhabit the U.S. They range across nearly all states and are especially common in the Southwest. These being studied are prairie rattlesnakes, which can be found in much of the central and western U.S. and into Canada and Mexico.
Like other pit viper species but unlike most snakes, rattlesnakes don’t lay eggs. Instead, they give birth to live young. Eight is an average-size brood, with the number depending on the snake’s size, according to Roberts.
Roberts is studying how temperature changes and ultraviolet sunlight affect snake behavior. Another graduate student, Owen Bachhuber, is studying the family and social relationships between rattlesnakes.
The researchers watch the live feed all day. Beyond that, they’re getting help from as many as 500 people at a time who tune in online.
“We are interested in studying the natural behavior of rattlesnakes, free from human disturbance. What do rattlesnakes actually do when we’re not there?” Roberts said.
Now that the Rocky Mountain summer is cooling, some males have been returning. By November, the camera running on solar and battery power will be turned off until next spring, when the snakes will re-emerge from their “mega den.”
By almost every measure, the 2026 Rockies are better than the ’25 Rockies. And, by almost every measure, the Rockies have a long way to go to become a contending big-league baseball team.
After getting bludgeoned by Kyle Schwarber and shut down by ace lefty Cristopher Sanchez in a 6-0 loss at Philadelphia on Sunday, the Rockies are 16-25 with one-quarter of the season in the books.
Schwarber hit solo home runs in the first and second innings off right-hander Tomoyuki Sugano, who gave up five runs on seven hits over five innings. Sanchez dominated Colorado for seven innings, giving up six hits, striking out seven, and walking none. He reduced his ERA to 2.11.
It was a step back for Colorado, but a week ago, Paul DePodesta, president of baseball operations, said, “We’re certainly encouraged by a lot of what’s going on, but at the same time, far from satisfied.”
Here’s a look at the state of the Rockies at the quarter pole:
• On pace: The Rockies’ .390 winning percentage has them pointed toward a 63-99 record. That would be a 20-game improvement over their 119-loss season in 2025 and enable them to avoid the infamy of being the first team since the 1961-64 Washington Senators to post four consecutive 100-loss seasons.
• White Sox meter: Chicago’s Southsiders lost a major league record 121 games in 2024. At the quarter pole last year, they were a miserable 12-29, but they eventually finished with a 60-102 record. That was a 19-game improvement.
• Road conditions: Colorado was laughably bad on the road last season, going 18-63, averaging just 2.81 runs per game, and getting outscored by 213 runs. The ’26 Rockies no longer look like automatic roadkill. They are 8-14 away from Coors Field but 6-4 over their last 10 games. They are averaging 3.95 runs per game on the road.
• Rotation in motion: The ’25 Rockies finished with a starters ERA of 6.65, the worst in the majors since ERA became an official statistic in 1913. This season’s starters own a 5.27 ERA, still the worst in the majors, but an improvement. Toss out the innings thrown by “openers” and the starters’ ERA is 5.11.
• Ace in the making? Right-hander Chase Dollander, who has the pure best stuff on the staff, is exponentially better this season than last — 3.35 ERA vs. 6.98 ERA as a rookie. On Friday, he held the Phillies to two runs and three hits in 5 2/3 innings, but walked five in the Rockies’ wild, 9-7, 11-inning victory. Dollander’s command was not sharp, but he didn’t implode as he might have last season.
“Every outing is different, for everybody,” Rockies manager Warren Schaeffer told MLB.com. “Today, for Chase, he had to battle command issues, but his stuff is so good that he was able to stay in it. He competed, and he kept grinding without his best command.”
Trade material: Except for Dollander, Colorado’s four other starters are all veterans in the final year of their contracts. That makes them possible trade candidates at the Aug. 3 deadline, if not before.
However, after a strong start to the season, the starters are beginning to fade. Lefty Kyle Freeland (1-4, 6.00 ERA) has a vesting option worth $17 million for 2027, but he needs to pitch 170 innings to activate that option, and it’s doubtful he will. There is a $9 million team option for right-hander Michael Lorenzen, but considering that he is 2-4 with a 6.92 ERA and a 3.56 batting average against, it’s doubtful the Rockies would pick up his option. But are either Lorenzen or Freeland tradeable?
That leaves lefty Jose Quintana (1-2, 3.90 ERA) and Sugano (3-3, 4.07 ERA) as the most attractive trade pieces. And throw in reliever Antonio Senzatela (2-0, 1.11 ERA), too, because he’s also in the final year of his contract.
Somehow, someway, the Rockies are going to have to restock their pitching cupboard for next season and beyond. It’s a predicament that DePodesta and company will have to solve.
Men of mystery: The hope was that this would be corner outfielder Jordan Beck’s breakout season, and that centerfielder Brenton Doyle and shortstop Ezequiel Tovar would bounce back. It’s early, but it’s not happening.
After going 1 for 3 on Sunday, Beck is hitting .169 with a .490 OPS. Doyle (.196, .529, 33.6% strikeout rate) is showing signs of rebounding, as is Tovar (.197, .277, 28.6%), who had two singles on Sunday. Still, the trio is underperforming. Beck and Doyle are often supplanted in the lineup by Mickey Moniak and newcomers Troy Johnston and Jake McCarthy.
After a 1-for-4 performance on Sunday, Moniak is hitting .303 with a 1.004 OPS and leads the Rockies with 11 home runs. Moniak has had hot streaks before with the Angels, but then faded. However, the Rockies believe he can sustain his success.
He’s arbitration-eligible for one more season, leading to plenty of internet trade speculation. But if the Rockies don’t believe their outfield prospects are ready to carry the load, signing Moniak to a reasonable contract extension makes sense. He’s making $4 million this season.
First addition: Utility infielders Edouard Julien and Willi Castro, and outfielders Johnston and McCarthy have all contributed to Colorado’s improvement. But it’s rookie first baseman TJ Rumfield who looks like part of the Rockies’ foundation for the future.
He’s slashing .272/.337/.429 with five home runs and is tied with Moniak for the team lead with 21 RBIs. Among all qualified rookies, he is tied for first in games played (40), second in hits (40), fifth in RBIs (21), and eighth in batting average. He’s also a terrific fielder.
Rumfield is everything the Rockies hoped Michael Toglia would be.

A Boulder County man was sentenced to 48 years in prison for murdering his ex-girlfriend and dumping her body in 2024.
The Boulder County Sheriff’s Office said Christine Barron Olivas’s body was discovered in a remote area of unincorporated Boulder County on Sept. 14, 2024. She was last seen leaving the neighborhood with her boyfriend, Carlos Dosal, the week prior.
The coroner’s office determined the cause of her death was strangulation.
In Feb. 2026, Dosal pleaded guilty to second-degree murder as a crime of domestic violence in her death. On Saturday, the judge sentenced him to 48 years in the Colorado Department of Corrections.
