A Twitter photo and a phone call from a Washington, D.C. resident helped animal keepers from the National Zoo track down a red panda in a nearby neighborhood after it went missing, the Associated Press reports.

The red panda, named Rusty, was found in a tree near a home in the Adams Morgan neighborhood on Monday, National Zoo spokeswoman Pamela Baker-Masson told the Associated Press.

"We just had to approach him carefully," senior curator of the National Museum Brandie Smith told the news service. "We are surprised by the distance he was able to cover."

The resident discovered the red panda and immediately tweeted a photo of the endangered animal and proceeded to call the city animal officials connected with the zoo.

Although the red panda is in the National Zoo's custody and did not experience any injuries, it is still unknown how he managed to escape the facilities - security camera footage does not reveal a possible escape route or suspects.

"There is no obvious point that Rusty could have gotten out of the enclosure," Smith said, adding that it had held red pandas for years, according to the Associated Press. "We all know that young males like to test boundaries."

Red pandas originate from the Himalayan region of Asia and are largely considered endangered by many environmentalists. Approximately 10,000 of the species, who are native to China, remain in existence.
