A historic train drew a huge crowd in Pennsylvania on Thursday, but the extreme heat came with it. Officials in Berks County declared a mass-casualty incident after more than 100 people waiting to see “Big Boy,” billed as the world’s largest steam-powered locomotive, suffered heat-related problems at the Reading & Blue Mountain Railroad Outer Station in Muhlenberg Township, reports UPI, citing local media. Temperatures hit about 106 degrees Fahrenheit as the train’s arrival was delayed for more than an hour.

Emergency calls began around 1:30pm local time. Forty-five people were taken to local hospitals, with one person who went into cardiac arrest revived before transport, authorities said. Children and older adults made up most of the patients. Big Boy ultimately passed through the station around 2:30pm en route to Philadelphia.

With Independence Day festivities looming, Muhlenberg Police Chief Randall Hoover cautioned that revelers should prep for continued heat, per NBC Philadelphia, which notes that some attendees at the Big Boy event had started showing up as early as 9am. “Heat is going to be an issue, stay hydrated,” Hoover advises. The CDC notes that heat-related illnesses can run the gamut from heat rash and cramps to heat exhaustion and heat stroke, per ABC27.

A bird that most people never see outside of pictures was found under a car in Pennsylvania, animal experts said. 

The Raven Ridge Wildlife Center in Lancaster County said in a Facebook post on Friday that an albino cardinal was found under a car. 

The nonprofit wildlife rehabilitation center in Washington Borough said it received a call from a woman who found a white bird under her car that appeared to be injured. The bird was also trying to drink water from beneath the vehicle. The post said that due to the dangerous heat wave, it has been admitting any distressed or unusually behaving animals for examinations. 

When Raven Ridge Wildlife Center’s team arrived at the scene, they said they were “instantly taken aback.” 

“Our eyes widened and our jaws dropped as we realized we were witnessing a rare occurrence that most people never see outside of pictures. This was a fledgling albino cardinal,” the Facebook post said. 

The chances of seeing an albino cardinal are “extremely low,” the center said, adding that albino cardinals are considered one of the rarest bird sightings. Estimates suggest that seeing any cardinal displaying white feathers is about 1 in 30,000, the center said.

“True albino cardinals, which lack all pigmentation, are even rarer,” the center said. 

What is the albino cardinal? 

The albino cardinal’s rarity is due to a genetic mutation that causes a lack of melanin, resulting in its distinctive white plumage and reddish-pink eyes, officials said. 

According to the center’s Facebook post, albino cardinals face “significant” survival challenges due to their “conspicuous coloration,” which makes it difficult to evade predators. The animal’s lack of melanin can also lead to poor vision. 

Raven Ridge Wildlife Center rescued the bird, which will remain in captivity because its chances of surviving in the wild are “slim.” 

“What an amazing opportunity for our team to see and care for this beautiful Cardinal,” the Facebook post concluded with.
