Why Are Pandas in America on Loan, and Why Do They Have Black and White Fur?

Category: Living Things

When news breaks that pandas are arriving in the United States, one might wonder: were they bought or gifted? The answer is neither. Pandas are actually "borrowed" from China. But why is this the case? And what is the secret behind their distinctive black and white fur? This article explores the rules of panda loans, the science of their coloring, and the careful work done at zoos.

1. Two Pandas Are Arriving at the Atlanta Zoo

On September 24, 2026, Chinese President Xi Jinping spoke at a ceremony at the White House. He stated that two pandas would arrive at the zoo in Atlanta, Georgia, within days [1]. The pandas are named Ping Ping (male) and Fu Shuang (female). Both were born at the Giant Panda Breeding Research Base in Chengdu, China. Ping Ping was born on March 17, 2020, and Fu Shuang on October 18 of the same year [3]. President Xi called the pair "ambassadors of friendship between the Chinese and American peoples." The loan agreement was announced by the China Wildlife Conservation Association in April [2]. The zoo also confirmed a new agreement with the association on April 23 [3].

Atlanta’s zoo previously hosted pandas. An earlier agreement started in 1999 and lasted about 25 years, during which seven cubs were born. However, the pandas at the zoo moved to China in October 2024 [3][4]. As of the news report, the zoo had not yet announced the exact arrival date [4]. The phrase "arriving" hides a complex story of lending and borrowing.

2. Why Pandas in the US Are Loaned, Not Sold or Gifted

The history of pandas in the US began as gifts. In April 1972, after President Nixon visited China, a pair of pandas was gifted to the Smithsonian’s National Zoo in Washington, D.C. [5]. Japan also received pandas, Kang Kang and Lan Lan, that same year [6]. Around 1984, this system changed to long-term loans [6]. Zoos typically pay between $500,000 and $1,000,000 per year for the loan [6]. For example, under the 2024 agreement, the Smithsonian pays $1,000,000 annually to the China Wildlife Conservation Association. Any cubs born at the zoo must return to China by age 4 [5].

This is similar to a museum borrowing a rare painting. The owner does not change, and the borrower pays a fee to support conservation. However, unlike a painting, pandas have babies. Legally, pandas are protected under the Endangered Species Act (ESA) in the US and listed in Appendix I of the Convention on International Trade in Endangered Species (CITES). These laws restrict commercial use and international trade. The U.S. Fish & Wildlife Service explains that US zoos do not own pandas; they borrow them from China as part of scientific conservation plans [7]. In Japan, twin pandas born at Ueno Zoo left for China on January 27, 2026, leaving Japan without pandas for the first time in about half a century [9].

3. How Panda Loan Fees Help Protect Wild Pandas in China

The Smithsonian states that the $1,000,000 annual fee supports research and conservation in China [5]. The U.S. Fish & Wildlife Service requires plans showing how the money contributes to conservation and records of how funds are used in China [8]. The Atlanta zoo says the new agreement allows them to support habitat restoration and on-site rangers [3].

How many wild pandas are there? A 2014 national survey found 1,864 pandas, a 17% increase over the previous decade [11]. In September 2016, the International Union for Conservation of Nature (IUCN) changed their status from "Endangered" to "Vulnerable" [10]. However, they are still at risk. The WWF warns that habitat fragmentation, unplanned infrastructure, and climate change remain threats [11]. The San Diego Zoo Wildlife Alliance notes that pandas are not completely out of danger [10]. While details on exactly how fees are spent are not fully public, the goal is to protect the roughly 1,900 pandas living in the mountains.

4. Is a Panda's Black and White Fur for Camouflage or Signals?

Pandas look very visible in zoos, but in the wild, their colors might serve a different purpose. In 2017, researchers at the University of California, Davis, compared panda fur to 195 carnivore species and 39 bear subspecies [13]. They found that pandas do not hibernate and move through various environments, from snowy mountains to forests [13].

The white on the face, neck, belly, and rump may help hide pandas in snowy environments. The black on the shoulders and legs may help them blend into dark forest shadows [13]. The black around the ears and eyes might be signals to other pandas rather than camouflage. One theory suggests the ears signal "I am tough," while eye patches help identify individuals [12][13]. This may help pandas blend into snow and dark forests, like wearing two coats at once. However, pandas cannot change their fur color; it is genetic.

A 2021 study analyzed 15 photos of wild pandas in Shaanxi Province, China, using human, dog, and cat vision models. It found that black fur matches dark tree trunks and shadows, while white fur matches snow and bright leaves. Beyond about 50 meters (164 feet), the panda’s outline blends into the background [14]. However, this study used only 15 photos from one location. It does not rule out the idea that eye and ear markings are signals [14]. The debate is not settled [14]. Researchers noted that claims about temperature regulation or reducing glare had weak support [12].

5. How Zoos Feed Pandas About 45 kg of Bamboo Each Day

Wild pandas spend more than 10 hours a day eating bamboo [15]. Their digestive system is more like a carnivore’s than a herbivore’s, so much food passes through undigested. This means they must eat large amounts [15]. At the Smithsonian’s National Zoo, staff provide about 45 kg (99 lbs) of bamboo per panda per day [16]. Staff harvest bamboo from managed forests near Washington, D.C., 3 to 4 times a week. They wash it, cool it with water mist, and store it. At least two types of bamboo are offered so pandas can choose [16].

Pandas are picky eaters. Some days they eat only leaves; other days they eat many stems. They may even refuse their favorite bamboo. Leftover bamboo is given to Asian elephants and gorillas [16]. Besides bamboo, pandas receive carrots, sweet potatoes, apples, pears, and "panda bread" made from soy, rice, and corn flour [16]. Zoos also create enrichment items like shaved ice to mimic snow, climbing structures made of logs and fire hoses, ropes, water pools, spice bags, and balls [17]. Keepers observe each panda’s personality—some are cautious, others jump in quickly—and adjust the items accordingly [17].

6. Why Panda Breeding Chances Are Rare and Health Checks Are Voluntary

Female pandas accept mating for only 2 to 3 days a year. They give birth at most once every two years [15][18]. Newborns weigh 85 to 142 grams (3 to 5 ounces), are pink, hairless, and blind. They are about 1/900th to 1/1000th the size of their mother [15][18]. Keepers look for behavior changes and hormones in urine to find the right day [15]. In Atlanta, seven cubs were born over about 25 years [4].

Health checks are also special. At the Smithsonian, pandas participate voluntarily. They undergo blood pressure checks, heart and abdominal ultrasounds, X-rays, vaccinations, and blood draws while awake [19]. Training starts with "targeting": touching a ball on a stick with their nose earns a treat like apple or sweet potato. Young male pandas start practicing at about 9 months old. For blood draws, they enter a hallway, put their arm through a window, and hold a bar. This training took about 7 sessions [19]. Pandas can choose whether to participate [17]. Awake exams provide more accurate health data than those under anesthesia [19].

7. How to Investigate Panda Colors Yourself

If you want to explore further, look at panda photos in encyclopedias or on zoo websites. You can also use a stuffed panda. On paper, write "white parts" and "black parts." Predict which parts would blend into snowy mountains and which into dark forests. Then, compare your predictions with Section 4 of this article to see what you got right or wrong. This article did not investigate if the same reasons apply to other black-and-white animals like zebras or orcas. Use the hypotheses about pandas as a starting point to research other animals separately. The arrival and public viewing dates for the two Atlanta pandas were not announced when this article was written. Check the zoo’s official website for updates [4].
